Hello all,
I'm trying to setup a 75g Fowlr but it seems like I made my first mistake,I used tap water with a conditioner.Now I've decided to get an RO/DI unit but it seems like the tank has cycled already,nothing in the tank yet but 75lbs. live rock.Ammonia and nitrite are 0 but nitrate is still 10-20 despite a 25% water change.Now the question is do I replace the water 100% with the ro/di or do it slowly with water changes?Also have a slight diatom bloom on some rocks,is this normal at this stage?What should I do?Thanks in advance for your time.
