I have a small water fall feature that the birds love for drinking and bathing! Yes, it gets sludge from their use. Will the "Tetra Pond Sludge Reducer with Clear-Zyme Technology Water Conditioner" harm the birds in any way?
Answer by ChewyAug 15, 2017
This is an all-natural, enzymatic product and will not harm the birds.

Can this product be used in horse water tanks in combination with the mosquito dunks? I’m trying to keep the bugs and the algae at bay.
Answer by ChewyJun 08, 2021
This conditioner has not been tested in relation to horse water tanks. For controlling algae and insects in water troughs it is recommended to frequently drain and clean.

Is this product safe to use with frogs, toads & salamanders coming to my pond? Also, is it safe if my dog happens to drink from the pond on occasion (which he does!)?
Answer by ChewyJun 21, 2020
This natural water conditioner is safe for all pond life including fish and reptiles. The manufacturer has not tested it on this with dogs and other mammal species since they do not exist in ponds, but this is an all natural product. The manufacturer does not recommend allowing dogs and cats to drink from ponds since they can pick up various illnesses from water that tends to be still or is not changed often.

Can it be used with a red eared slider in the pond?
Answer by ChewyNov 26, 2018
The manufacturer recommends using this water conditioner without the turtle in the pond.

Drastic improvement

Used 2 tabs once a week for 4 weeks along with cleaning filter every other week, definitely cleared the water. Can see through to bottom of the pond.

I have bought this for years

I’ve been using this in my pond from the time we built it. It’s not quite as big as a 250 gal but I’ve never had a problem using it. Being I have more gold fish than I should for this size pond due to them breeding and they still seem happy, I’m happy.

No help here

Tried to use it before the pond got too bad, but this didn't help, made it worse actually.

Small pond

I use these in my 600 gal pond to break down sludge from all the fish poo; use 2 per month.

not working that great

Our pond was definitely in need of something... I'm not sure this was the product... It cleared up a little bit but since the first tablet, it got super hot here in Maryland (we don't have spring, straight from winter to summer)... so I haven't treated it with the remaining tablets as the warning indicates in hotter weather, it is not recommended. I'll keep the tablets though and if we get a cool snap, I will treat again, or worst case scenario, the fall.

WOW this is the BEST

This is AWESOME, I have tried everything out there to keep my small pond clear. Love to watch my fish, however it was usually to dirty to see them. I changed the filter, I drained the pond I put in algae clear and everything else, no good. Bought this product, and wow what a difference, put 2 in to begin with then one every month, that's it. Now I just have to put clean filter in every few months. Was ready to fill pond in and plant flowers, now it is beautiful and I can enjoy it. Best Product EVER. I hope they never stop selling it.
