Spring Jobs For Your Pond

It’s March 20th and spring is officially here so it’s time to start working on your pond, clearing up after the winter and preparing for the rest of the year.

Most of the UK had a mild winter and despite the Met Office’s warning of Thundersnow back in January, we haven’t had much snow or ice this year. Because of the milder temperatures, there is a possibility that pond sludge and algae have been active in your pond for a good proportion of the winter months as they can grow down to temperatures as low as 8°C.

Preparation Is Key

First things first, if you have any plans for your pond this year, now is the time to start putting them into action. Make sure you have all your pond maintenance supplies and feed stocked up, there is nothing worse than running out of something when you need it most! Go over your filters and pump and make sure everything is clean and working as it should be.

Remove Debris

Remove any obvious debris that could have made its way into the pond over winter. Small pebbles, rocks, leaves & twigs can all be blown or washed into your pond and if they degrade, they will eventually turn into pond sludge. Be sure to clear any loose debris from around the edges of your pond as well as these will make their way in.

Inspect all your aquatic plants and remove any that have not survived the winter. Remove any dead leaves and trim back accordingly.

Pond Sludge & Algae

As we mentioned above, the winter has been mild and pond sludge may have been active in your pond for a few months now. Be sure to use your Pond Klear and Sludge Klear early as it can work down to temperatures as low as 4°C. If you have been using Winter Pond throughout the winter months you may not have much sludge so have a look before dosing up.

pH Levels

Your pond hasn’t had much attention for a few months and although chemical and bacterial levels don’t change much in the cold, it is always good practice to use a test kit to ensure your water conditions are perfect.

Poor water quality and the fast transition in a ponds conditions coming out of winter and into spring can lead to “spring kill” which refers to the loss of fish at the start of spring due to series of related water quality issues

Why Do Ponds Go Green In The Spring?

Ponds turn green in early spring. That’s pretty much gospel among pond keepers; it’s just the way things are.

Why does it happen?

Basically, there are two types of bacteria in a pond – aerobic (good) and anaerobic (bad).  These two types of bacteria are in a constant battle to digest the organic debris that ends up in the pond (twigs, leaves, fish food etc). When the anaerobic (bad) bacteria digests it, it takes a lot longer and produces gases like nitrogen and phosphorus which, in turn, act as a food source for algae. When we add aerobic (good) bacteria to the pond, they overcome to the anaerobic (bad) bacteria and digest the organic debris a lot quicker and don’t create any harmful gases. This is why, when you use bacterial pond treatments you are getting to the source of the problem; rather than just eating the algae, you are starving it of its food source.

The problem is that anaerobic (bad) bacteria can digest organic matter as low as 6°C, whereas aerobic (good) bacteria treatments traditionally work around 10-12°C. This means that all winter your pond is losing the battle against algae and when spring comes, the algae starts to feed.

It’s all about to change

Envii Winter Pond Treatment is a new type of aerobic bacteria treatment.  It works as low as 4°C which means that you can win the battle of the bacteria all year round.  Its task-specific bacteria digest the organic debris meaning that when you come back to pond in spring, it will stay clear. Then continue to treat with Envii Pond Klear and your pond will never go green again!

This is the first pond treatment designed to work all through the winter!

How To Prepare Your Pond For Winter

When should I stop feeding my fish?

When the pond water temperature drops below 13°C for over 10 days you can stop feeding the fish. Change to a wheat-germ based food for a few weeks before this as it’s easier to digest and won’t get stuck in their stomach.

Once you have stopped feeding the fish DO NOT start again. Even if the temperature rises above 13°C don’t be tempted to start again as it could quickly drop again and food could get stuck in the fish’s intestinal tract.

Clean out the pond.

  • Scoop any debris out of the top of the pond with a fine net.
  • Use a pond vacuum to remove sludge from the bottom of the pond.
  • If possible, physically clean anything else from the pond without harming the fish. You could do a partial water change to allow easier access to the bottom of the pond.
  • Use Envii Pond Equaliser to restore the biological balance to the pond.
  • Attach a pond net around 18″ above the pond surface (leave a few small holes if your pond has frogs or other wildlife that needs to get in and out).

Should I turn my pond pump and filter off?

This depends on where you are in the world. If you live in a really cold climate where the pond is likely to freeze over, then it is best to turn all the equipment off. This is because the fish will hibernate in the warmer water at the bottom of the pond and a pond pump will move the colder surface water around the pond and disturb the warm water.

Generally in the UK you should be fine to leave the pump and filter running as normal.

Treat with Envii Winter Pond Treatment 

Envii Winter Pond Treatment is a revolutionary pond treatment that works all winter. It’s the first of its kind because it works as low as 4°C to break down the organic material that builds up in ponds over winter.

This organic material (twigs, leaves, fish food, acidic rain, excrement etc.) acts as a food source for algae which means that in the spring you will find a pond full of algae.

By using Envii Winter Pond Treatment, you can now keep your pond topped up with beneficial bacteria all year round.

Customer Stories – Adrian Rodgers

Here’s a great review we recieved about Pond Klear from Amazon Customer, Adrian Rodgers –

“For as many years as I can recall our well stocked fish pond has turned green in spring and we haven’t seen a fish until almost autumn. We’ve tried plants (much to the delight of our grass carp), as many chemical remedies to reduce the algae bloom as there are on the market and traditional barley hay. It’s safe to say that we have never known what eventually gets on top of the problem, it just clears one day.

This year however is different. We introduced your product in early April during which, luckily for us, there was a really cold spell which, presumably delayed the onset of our annual algal bloom problem. Your product states that it works at cold temperatures but nevertheless given our 10 year experience of green water and the multiple products used I must say not much success was anticipated. I’m delighted to state that I was completely wrong. I followed up with a second dose a week later and at about 1 month from dose 1 I’ve added a third. We’re now mid May and the pond is delightfully clear despite the warmer weather and long daylight hours. We no longer have to wait until feeding time for a glimpse of a fish mouth!

Further, the slurry I remove from the filter box no longer sends a whiffy bad eggs aroma up my nose when I lift the lid and I suppose this is a further effect of your product.

An excellent product which I will buy again.

Regards

Adrian Rodgers, delighted customer.”

Customer Stories – Wolfhound Mum

“Wolfhound Mum” bought a bottle of Pond Klear on Amazon. Here’s what she wrote about her experience

“After having problems with both my UV lights, the water in my pond had become really bad, not only green, but the debris suspended in the water made it impossible to see all but the largest fish (& then only when near the surface). I bought this on a whim, not really convinced it would work, it seemed too good to be true. Wow… This stuff is amazing. I used double the dose as recommended for the 1st application on a Wednesday night & by Friday morn’ not only could I see all my fish, I could see the bottom of the pond. The fact it was harmless to dogs was essential as even though my pond is raised, our wolfhounds use it as a large drinking bowl. They are all fine but probably scare the heck out of my previously sight impaired fish. Can’t recommend enough. I would not have been able to see these fish just 4 days ago.”

How To Clean A Pond Without A Filter

We’re constantly being asked –  Will Envii Pond Klear work on a pond without a filter?

The short answer is that it does work on ponds without filters.

Here’s the longer answer…

The bacteria in Pond Klear eat the organic matter (i.e. twigs, bird poo, fish food etc) that decays causing algae and sludge. However, it would be a tall order for them to eat all of the algae and sludge created so they also detach it from any surfaces and clump it together allowing it to be caught in the filter.

So Pond Klear WILL work in a pond without a filter but it won’t work anywhere near as quickly.

Because of this we generally recommend that people use Pond Klear Xtra and Sludge Klear in a pond without a filter. These products together have a far higher concentration of bacteria and work in tandem to eat the organic matter. While it is more expensive, you are guaranteed results.

It’s also worth physically cleaning your pond as best you can by removing anything from the surface. This will give the bacteria less to do and make it work quicker.

Pond Klear – 10 Day Test in Fish Pond

Over the last two weeks or so, we’ve been testing Pond Klear in a real-life situation. A customer bought a bottle of Pond Klear Xtra and approached us for some advice and after hearing how green his pond was we saw a great opportunity to show what our product is capable of.

IMAG0506

This is the pond, complete with an unsightly metal gate to keep the herons out. Believe it or not there are a few beautiful fish hidden in there but we had to take his word for it! We put 150ml of Pond Klear Xtra into a bucket of pond water and distributed evenly over the pond surface. A normal dose for a pond of this size would be 50ml but we always recommend starting off with a double or triple dose to allow the bacteria to become established.

 

 

Pond Test Day 1

This picture shows the pond after 1 day. As you can see the bacteria has started to take effect. The fish are just about visible although it’s very difficult to see any of their patterns. The floor of the pond is definitely not visible and there is a strong green colour to the water.

 

 

Pond Test Day 5

This is after 5 days. There is a clear difference; the structure of the pond is visible; the fish are visible (but quite hard to spot in this picture); and the pond generally looks a lot healthier. At this point we gave the pond another standard dose (50ml) of Xtra and cleaned out the filter. It’s extremely important to clean the filter as often as possible because the bacteria in Pond Klear will dislodge a lot of organic material which will then get caught in the filter. While this is a good thing, if too much material gets stuck in the water it will stop working.

 

 

Pond Test Day 10

This shows the pond 10 days after first dosage. As you can see the Pond Klear Xtra has completely cleared the pond. The floor of the pond is visible and you can even see the frogspawn hidden beneath the surface. This really shows how effective Pond Klear can be if it’s used correctly.

There are a few reasons Pond Klear has worked so well on this pond –

It has a working filter – The bacteria in Pond Klear (and all Envii Pond products) do two things. They eat some of the organic material and dislodge the rest. This means that the organic material that has been dislodged (or disturbed) will then be sucked into the filter. If you clean your filter every few days while treating Pond Klear will work considerably faster.

Started with a triple dose – You can’t really overdose with Pond Klear. While we wouldn’t recommend putting a whole bottle in, it’s perfectly safe to start with a double or triple dose. Bacteria reproduces logarithmically (1 becomes 2, 2 becomes 4 etc.) so by starting with a strong dose it will get to work much quicker.

Used Pond Klear XtraPond Klear and Pond Klear Xtra are exactly the same except Xtra is 3x stronger. For a pond as green as this one we’d always recommend using Xtra as it will get to work much quicker. At £27.99 you get the equivalent of 3 bottles of Pond Klear for the price of 2.

No UV lights – UV lights kill both good and bad bacteria. This means that, while they do help keep your pond clear, they will render any bacteria treatment useless. If you have any UV lights make sure to turn them off for 2-3 days during treatment.
