ro water for marine aquarium
1. I am starting a new marine aquarium. I made the water with tap water and coralife salt. Put in some live rock 3 weeks ago and now have a coating of brown which I think is a diatom bloom. I have read I need to change water over to RO water to get the diatoms to die off. Can I just buy some bottled water such as culligans or hinckley or do I have to schlep over to my fish store that is not too close by to get RO water from them?
2. My ammonia is zero, nitrites are zero and nitrates 5-10 so I think the tank has cycled. Can I add fish during this diatom bloom?
