Evolution Aqua Pond Dechlorinator for Fish Ponds – Activated Carbon Chlorine Remover Garden Hose Inline Water Filter for Pond Tap Water Treatment / 12-Inch

I came across these when I was looking to reduce the blanket weed growing in my pond, and I believe this will take out the nutrients feeding the weed as well as dechlorinating the tap water which I previously let sit in my water butts for a few days to dechlorinate, but apparently this didn't deal with the weed problem as I should only use filtered water or rain water which is difficult when it doesn't rain. Now mounted vertically with a recommended 4" pipe clip, which had a 3mm gap around it when closed - so it didn't fit. I found some suitable neoprene material to fill the gap, and it is now held snugly - it was a bit of a flaff to fit. The flow rate that I use is between 2-3 LPM to make sure that water is filtered thoroughly, and it probably takes up to a couple of hours to fill a full size water butt which is my pond reservoir. I am very pleased with it and it should last me 4-5 years before it will need replacing - maybe longer, but I will never really know when it is exhausted unless I test the water periodically - which I don't.

So far so good, a lot simpler than messing about with chemicals. I’d advise you to get a inline water meter so you know what 4 litres a minute looks like or you can see the flow rate in my video below.

It works well, I've had no problems with water tests easy to install, although, when you get the package there is further information, i.e to keep out of bright sunlight to protect from forming Algie inside

Perfect for topping up the pond and ensuring the fish stay healthy

Excellent product for topping up pond slowly and protecting fish

Easy to use, fish seem to like it. Delivered in good time and in good condition.

I have been using the dechlorinator on my pond for above 12 months. The pond water is crystal clear, and the nitrate/nitrite levels in my pond are zero.

We bought this to top up the pond water and water our plants without chlorine. This worked wonderfully at first but after a few months I have started to see constant accumulation of carbon bits escaping the tank and getting lodged into my spray gun. It needs constant cleaning and loads of carbon bits would fall out each time I clean it. This is not OK as it can ruin nozzles and sprays. This also makes the water pressure very weak because on top of the filter itself reducing pressure, the loose carbon aggravates the issue.

Bought this product base on great reviews BUT when i received my order all carbon inside keeps falling, might be factory defect. and the refund takes 8 days, if i didn't contact amazon CS maybe my refund will take longer than the set timeframe. Amazon.ae needs to improved especially bad CS department, you are giving favor for your rivals
