So I finally got water in my new 54 cube and its cloudy. This is straight, fresh RO water, no salt has been added yet. I noticed the same thing early this year when I set up a frag tank. At that time I filled the frag tank with water and salt at the same time so the water would normally be cloudy. The FT's LED lighting really made the water look milky. The FT has never fully cleared up and I blamed it on the salt mix I used. Now I'm thinking its the water. I have been doing this for years and never had a problem like this. My water has always been crystal clear once the salt is full dissolved. The RO membrane is almost new and the water tests good for TDS. I wanted to wait before I add the salt to see if there is a good way to clear it up. Any suggestions?
