I am looking to buy I better filter, because I am sick of the 318 filter. I only have 20 gallons in the tank, and both (yes I have two) can't keep it clean for more then half a week( 3 to 4 days and I lose that clear look to the tank).
I am looking to upgrade my filters, but anything I get I won't be able to take to my next tank,(which I am hoping to get this fall) because of size(I want to get an FX5 for my next set up, but don't have the money right now, plus I don't know what the current would be like in 20 gallons).
So, is there anything cheap out there that will keep my tank clear, for at least a week? Or should I just get an XP1, 2, or 3(I really don't want to spend $100 on an XP3 just for 8 mouths though)?
Thanks for any suggestions in advance,
Nathan Radle.
