i prefer to over filter. i have a fx5 and ac110 on my 125g. its a little more stocked but i'd like to add another good sized hob or powerhead for movement in the tank
I feel like one should always add an ac110 if there's space on the back if they have the means. I don't believe there is such a thing as too much filtration. The FX5 is a great start.
Cool, I was thinking that myself. Good thing I have 2 AC110's sitting around from other projects. I also forgot to add I will be using 2 AC powerheads as well.
Well with that said, you should be good to go. The powerheads are a great idea and with those ac110's you will will have a ton of filtration. I also like keeping what ever filters I have going just so they are ready for something else if need be.
^ So true. With the powerheads you'd probably be fine but if the AC110's are available thrown them on, they'll keep the water moving and help you out with mech filtration.
having more than one filter on a tank will give you the ability to alternate times for cleaning too. This will help keep your BB alive and your parameters in check.
