Hello everyone.

I'm in need of some advice. I just purchased a 125 gallon aquarium off craigslist. Woohoo! It came with a Cascade Canister Filter 700 and two HOB filters which look pretty cheap. I'm currently running an XP2 on my 55 gallon along with an Emperor 400 and was planning on moving those over to the new tank. The new tank will start off with 1 medium sized Oscar and 1 medium pleco. I plan on adding one more Oscar in the near future. Do I have enough filtration or should I look into getting another filter? I was looking at the XP4 and thinking this might be the way to go. Thanks for the help.

you got some good location there, however, it never hurts to add more filtration if you can. Oscars are very messy fish, personally I like to have a minimum of double the filtration tank actually requires. The more filtration you have, the healthier the tank will be in the long run.

The XP4 is rated up to well over 200 gallons so whether you would need to still have the hob filter is debatable.

Thanks for the advice! I'll look into getting the XP4 or something comparable. I looked at the Fluval FX5, but it's a little more than I'd like to spend at the moment. I think with the XP2, Cascade 700, and XP4, I should be good.

with the filtration you listed you should be fine with only an oscar and a plec. even if you add another oscar the xp4 and xp2 will be more than enough to keep your tank clean and healthy

That's good to know. Thanks! I've found a XP4 on Ebay for a pretty reasonable price. Hopefully I can win it.
