Questions & Answers

7 Customer Questions


Is this product safe for dogs? My dogs drink from the pond
Answer by ChewySep 11, 2019
This product has not been tested on dogs but it's recommended that it's diluted into the pond first. Please allow the product to mix within the pond for a few hours prior to allowing the dog near the pond area again

Is this item okay for ducks? How long does it last?
Answer by ChewyOct 15, 2022
Tetra has not researched this product's use with ducks and does not recommend it. It is intended for water gardens and fish ponds only. This block dissolves very slowly, over a period of approximately four weeks (30 days).

I have a 35-40 gal ornamental fountain. These say use in 100-250gal. But I see some reviews that say they are used in smaller fountains. Can I break them in half and use them? Or would full strength be ok?
Answer by ChewyNov 05, 2019
Although the blocks can be cut, the "Tetra Algae Control Pond Fountain Block Water Treatment" is the same formula, but in smaller blocks, which may be more convenient for smaller fountains.

Can this be used in a turtle pond?
Answer by ChewyDec 22, 2022
Tetra has not done any research on the effect of that product on turtles so it is recommend not to use in a turtle pond.

Rated 1 out of 5 stars

Very Confusing

The label states "This pesticide is toxic to fish and aquatic invertebrates and may contaminate water through runoff." Why wasn't this in the description? I don't know what they keep in ponds, but I'm returning it!
