Hey guys. After a bit of research I think the CPR backpak 2 skimmer looks like a good option. I'm thinking of ordering tonight. my question is will it be sufficient for a 90 gallon tank (which I plan to upgrade in a years time). A couple of things.. I'm noticing a bit of reddish slime developing on the glass developing. Should I clean this off or wait for it to disappear ??
Secondly my water level seems to be dropping . I thing this is due to the lights. Is it normal?? I have the lighting on for about 7-9 hours a day. Any suggestions ?? Thanks guys
