That sounds about right. If you are starting with the 35% stuff you should dilute it 10/1 to get it down to around 3%. Makes it easier and safer to work with. I use a dosage of 300ml (3%) per 100 liters at reservoir change and 1/4 to 1/2 that amount daily. So a 10 gallon system would be 40...

Nah, it kills the good bacteria too. However, on balance I think it does a lot more good than bad. I've been using it recently in pretty high dosages and I must say my root systems really look good as do the plants they are part of. It is really quite noticeable.
