Ok so here is my problem. I don't have an RO
system yet and won't e getting one for another month or 2. I am going to be filling my 125g tank this week and I can only carry 10g to and from my RO
dealer at a time so I am thinking of using tap water. Now here is what I am thinking and let me know if you agree or disagree. The whole problem with tap water in a reef is that it has way more TDMs (total dissolved material) in it than RO
water, isn't a protein skimmer's job to remove the dissolved organics in the the water? So I am thinking. Use tap water and let the tank cycle with that water and do my water changes with RO
water. If not i will have to make an awful lot of trips to get water.
