In the process of setting up a 125 gallon tank for Red Belly's (about 7-10 2" RBP), and I have a Fluval 404 that I just purchased. I also have a HOT Magnum 250 filter I was given for free. Should I use both of these filters? How are effective are powerheads and should I buy one or two? Also, how effective are the undergravel filter systems ( I have one already), I was thinking to maybe set that up with the Magnum, but I dont know what will work best though. I figure some of you piranha experts have some good experiance in this field. I also purchased an Aqua Mist to produce alittle movement in the tank. Thanks guys.

Use both of those filters, get 2 powerheads are good to use. As for under gravel, I have never used them but people say they aren't that good. Others like them. Its up to you.

use them both
i have a powerhead 901 in my 125gal works really well but. but i have 6 (4'' - 7'') rbp's i'm not sure if thats to powerful for 2'' p's but you can turn the outlet up if its to much till they grow wont take to long! if your going with live plants you have to cover them really good or they will float arround or get sucked in the intake filter it kinda blows


i'm not one of the piranha experts

the powerheads will add current and oxygen , but thats about it, it wont help filtration or anything like that.

Should I purchase another Fluval 404 or just stick with the Magnum and Fluval. Yeah I plan on having plants and some driftwood and rocks.
