Cheers for info. Well the tank I'm going use is my old 33 gal
got filter but thrown the pads away but have spare so going put one in my sump but don't know which ones to use as got about 5 different ones, thinking just blue course and white polypad ones.
I started the hobby totally wrong but learning the best ways do things as I go so lucky not lose fish at min as seems like everything at once, well in a way it's a good thing as want add more rock and change the dt around so can do that till tanks ready for fish. I was thinking about getting qt for when I get some more fish after I finish the rock work as the lfs
fish don't always look that good anymore and it's the best one close to me.
