Maximum for an fx5

[jimboperu]

Now im just curious to see other peoples opinions on this. What would be the absolute maximum volume of water for only 1 fx5? I know a lot of people say 80, 100, 125, etc and even the bo of the fx5 says "up to 400 gal".... Yeah right, but lets hear your opinions

I have one on a 120 gallon and does a great job. I think anything bigger and you need to add another, I have one on a 180 with an eheim 2260 and it's about perfect.

I'd probably use one on my 135g but anything larger would need additional filters. I had two of them on my 180 and that worked great.

It depends on the stock volume. The limit of a filter is the quantity of biomedia contained. If one FX5 can handle the bioload of a specific stock but water circulation is not sufficient to maintain the biological params, then it would be cheaper to add powerheads instead of a second fX5.

One could clean 400 gallons in my opinion if you clean it twice a week and had other water flow in the tank to push the crap to the filter. I think no matter what extra flow sure I nice in all and any tank.

I use a fx5, wet dry rated for 125g and emperor 400 on my 90 and water change every week

I have 1 on my 90gal including ac110, but my fish are extremely messy, 5 medium sized rbp, its enough mechanical filtration to the point I don't even have to vac at all and it stays clean, although thats no substitute for wc, so 1x 60-70% per 5-6 days are necessary for lower nitrate levels (20-40ppm) max.

Bio filtration is still great with the fx5 media capacity at 1.5 gallons, which is full of bio media and 10x apprx turnover rate.

id say Atleast 1 for every 100 gals unless ur at max capacity in which case more filtration and more wc are needed. this does not include hob or added filtration.

Bingo. A single FX5 could easily filter a 600g if it was [very] lightly stocked, but might not be enough for a 100g if its crammed full of messy fish.

My favorite is to run one with sump also. But I have one running on a 55 gallon breeder over stocked that I clean monthly.
