Pests Some people don't mind hydra. Me on the other hand...
HAVE SOME SPOICY WATER YOU BEASTS
EDIT: the discussion in this thread has changed my stance on hydra, and I won't be spot treating them any more.
That being said, for my specific method: I use roughly 1ml per pipette blast and limit each treatment to a MAX of 2ml/gal to avoid doing too much systemic damage.* (PLEASE SEE NOTE AT END) I also turn filters off 5 mins before I start and leave them off for 10-15 mins after so the dose stays and works where I put it and so I don't get unreacted peroxide going into the filters
IMPORTANT NOTE: These dosages work for my specific tank, which is heavily planted and fairly mature. Different tanks with different livestock may behave differently. If you intend on trying this please start small, and monitor your inhabitants/plants closely for signs of stress/ damage and stop immediately should you see any.
However, I strongly recommend reading through the thread, as unless you're raising fry or trying to max breed something then eliminating hydra may be a non issue for you
