Using RO water

[Lex_510]

Hello, So I’m setting up a new 75 gallon tank with sump and I need a lot of water Fill it in. There’s a Water Mart a Water filter Store that sales filter RO water that is abt 2-4 TDS. Is that ok to use for a mix reef set up? Is it bad or good??

That is.ok. good. 0 is best.
Im gonna set up mine with 30-40 tds.garden hose tap water.
As long as you do wcs and top off with the ro water youll be good. The idea is to not keep adding tap water. Hths

I do water top up with RO water skates 5 tds. Not had issues. Thus is the same water that is used in fresh water tanks here in Australia perth. So obviously it's fine
