I’m new to salt water and have a few questions
1st how much R/O water should my auto fill be using I have a 300lt tank and seem to be filling my R/O refill tank up every couple of days it’s a 10lt tub . I’m running my tank at 25 degrees??
2nd I lost all my fish in a week the shop I go to said he thinks it was velvet. I still have a shrimp and some coral left should I still put food in the tank every day. The shop said I need to leave my tank for 8 weeks before I can put any fish back in it . The tank is 7 weeks old and all the tests was fine because the shop did a test for my . Any help would be appreciated??
