Survey- Your tank size versus filtration flow rate

[Scuba_dude]

I wonder how much filtration you feel sufficient for an aquarium

I would be very curious about what you consider the right number and why.

PS Indicate you mitigating factor (planted, overstocked, large fish)

I like 10gph filtation but i am a big fan of overfiltering a tank i have a 10gal right now and a penugin mini with a 100 [acronym:792c37be8a="Gallons per hour"]gph[/acronym:792c37be8a] rating on thier. I am going to buy a 29gal tank and am going to put the Penguin Mini and and Emporer 280 combined [acronym:792c37be8a="Gallons per hour"]gph[/acronym:792c37be8a] flow 380. I am going to have cichlids in the 29 so overfiltering it wont be bad at all.

Well, about 7 x tank turnover is what is generally recommended for your regular [acronym:c19079a692="Freshwater"]FW[/acronym:c19079a692] tank.

I have 2 190 [acronym:c19079a692="Gallons per hour"]GPH[/acronym:c19079a692] filters on my 55 gallon tank, giving me just 7 x turnover.

On my [acronym:c19079a692="Saltwater"]SW[/acronym:c19079a692] tank, I have about 7 x turnover with 2 200 [acronym:c19079a692="Gallons per hour"]GPH[/acronym:c19079a692] powerheads, so there is alot more flow.

I go with 10 x tank turn over on my tanks because I also like to overfilter my tanks.

I use the 10 x per hour on my Oscar tank because we all know what kind of mess they can make...

Ive got 170 [acronym:ea970ac312="Gallons per hour"]gph[/acronym:ea970ac312] on my 20L., so 8.5.

Here's my logic: Filter manufacturers will overstate the filters capacity for marketing reasons. So, I want 7- 10 X the tank volume (I like overfiltering to reduce service intervals and allow some overstocking). Therefor I take the manufacturers rating, cut it in half, then shoot for 5-7x turnover with the halved value. Am I certain that a filter in use will only be half its manufacturer rating? no. but as long as the current isn't hurting the fish, why not go overboard? Therefor for my 55 [acronym:1be1534eae="Gallon"]gal[/acronym:1be1534eae] Oceanic plus (which probably only holds 50 [acronym:1be1534eae="Gallon"]gal[/acronym:1be1534eae]) : Fluval 404 = 350gph manufacturer, devide by two = 175 [acronym:1be1534eae="Gallons per hour"]gph[/acronym:1be1534eae]. Two of them is 350 [acronym:1be1534eae="Gallons per hour"]gph[/acronym:1be1534eae] (halved value), which is 7x turnover. If the filter does better than half its stated rate, I get closer to 10x turnover. Plus I now have two filters, can service them independently, and will have one going if one breaks. Thats my logic, but perhaps there is no real logic behind a desire to overfilter.

I have well over 10x, so even using understated values, I probably have around 10x.
I think I figured my rate at 13x or so using the [acronym:885bb847ba="Gallons per hour"]gph[/acronym:885bb847ba] flow rate on the labeling.

I have about 220gph on my 10 gallon. Its just a Jack Dempsey but the great thing is i don't have to change filter media nearly as often as i woul with a smaller filter.

It is a Whisper 30-60.

My 125g uses a custom built filtration system with a Mag 9.5. It actually only flows about 400-500gph with a new filter, so when i'm back home I'll get a much larger pump. It will also help out a lot with the life of the filter. The water is absolutely crystal clear, its being filtered to 50micron.

I aim for 10x turnover, but have as much as 30x turnover on a few tanks.
