Hi. I'm currently using 2 Aqua Clear 50 filters on a 40 gallon tank....it keeps the water clean but the filter is a disaster after 2 weeks. I would like to get a canister filter, but don't know what to get.
At this time next year, I hope to have a 90 gallon tank, (money probably won't be the issue, it will be space), and ifI do get it, I'd like to use this filter on that tank.
I was considering the Penn Plax Cascade 1500, which claims it is rated for up to 200 gallon tanks.
This is in comparison to the XP3, which is rated for 175 gallon tanks. The XP4 isn't an option due to the cost and the fact that it would likely be overkill on the 40, and my local stores don't sell the media for it.
Please advise.
