It’s a must product
The best product to keep the ph down. Just one or 2 small drops otherwise you end up killing your fish. Great for fish health

It kinda works
I’ve attempted to use this product for a few weeks now I’m not sure if I’m using it right but finding it difficult to maintain a lower PH in my fishtank would be helpful if it had more information how to use this product, I guess that’s what Google’s for. Still seems like a reasonable price.

Great quality very strong
Works like a charm. Don’t add it to your tank if you’re dealing with an ammonia spike - it’ll make it worse. Only add when your parameters are spot on and balanced.
