Hygorzyme is more a preventer but With the fight on root rot I had to try something. We have a tub with 6 plants, all were developing the rot and roots turning brown but not killing the plants. Gave them just less than half dose on the bottle. After just changing the water once the roots are looking sooo much better and whiter and much new root growth. This will be a regular in the mix from now on. I would take it up more but don't want to shock them if it's working. Yeilds will be much better I'm sure.

Highly recomended for any stage of rot.

Interested to know how the Physan works on the brown algea as we have seen it before and dumped the whole thing trying to clean.
