HI there, it's been a while since I've started a new tank so need to ask some questions again. This is actually for a friend. He has a two week old 20g tank. He has 2 filters on it that supports 20g tanks. Is that not too much? He told me today his tank is very cloudy. I'm thinking because it's still in the cycle stage but I'm wondering if those filters are too much; one should be all he need. He bought test strips and stated all his levels are good. I advised he may want to get the liquid test kit because I don't think those paper strips are really that accurate. Anyone agree? Appreciate any help on this. Thanks.
