I went to my lfs today to see if they sold ro/di water, on there sign it said De-ionized water, 60 cents per gallon, is this considered reverse osmosis? Also they sell water pre-mixed with instant ocean sea salt as well as water pre-mixed with reef crystals, which water should i buy?
20 gallon tank
2 ocellarus clownfish
Mushroom coral, more specifically Green Ricordea
I dont know if i should mix my own salt, use reef salt or instant ocean, or buy a premixed saltwater
