There is no 'safe form' of ammonia, ammonium is just less lethal. BB is still able to consume ammonium anyway. Either way I want 0 ammonia and nitrite, still striving for low nitrates too, might have to set up a denitrator.
The barra will be gone soon which will help, he's a massive bio load on the system.
Thanks for the responses and help too guys, much appreciated.
Sorry I don't agree. Ammonium isn't toxic to fish, elsewise all the products that detoxify ammonia by converting to ammonium would be a waste of time.
