When accounting for how big you should go on a skimmer do you just account for dt or sump also? I have a 40 with a 20 gl sump.
Thanks arsalan... I have a diablo 150 in it now. It works well. Doesn’t seem to skim consistently though, I’m going to try cleaning it twice a week instead of once, hopefully it will be more consistent cleaning the buildup more often.Always get total water volume then go bigger. Not necessary per say but helpful. Less emptying of the cup and skimming out the junk faster.
I’d get one rated for 100g or so in your case.
