is this enough filtration? opinions please

[amosf]

I'd say yes, you're fine - I've got a FilStar XP2 on my 65g; it has a 300 gph flow rate, which means (if my math is right) it's turning over the tank volume 4.6 times an hour (and I doubt it's that much - they never have the flow rate listed on the box once they're full of media, mulm, etc.). It's rated for up to 75g so I'm pretty much maxing it out, and it's doing a great job.
It also depends what you've got in the filter - if you have lots of media designed for biological filtration (the little 'stars' made by Rena or bio-max, etc.) one XP3 should be fine for your tank even if it's a bit overstocked.

I would agree with Blinky. With the right media that should be enough filtration... I think I'm only getting about a 400% turnover with my current 50g setup, but with the media I have in it, and possibly because it's a wet/dry setup, it's doing an excellent job...

Yeah over filtration is definatly a good thing. My water turnover is crazy not including my UG filter my otherfilters pump 800 gallons per hour. Thats 32 times per hour my water is filtered or once every 1.8 minutes. Thats over filtration. But my tank is very overcrowded which is why i added extra filters... the nice thing is now I can upgrade to a bigger tank and not worry about buying another filter.

You've got more fish in the 25g than I have in a 50g

I did have an additional 700% filtration on the 50g for a while on top of the 400%, but really found I didn't need it with my stocking levels. It really depends on the tank and the fish...

woot 8x turnover well in theory at least

I think that many people try to aim for 5-6 times turn over rate as most people have at leats moderatley stocked tanks, if not over stocked. With some tanks like discus etc... there are peopel that like 10 times turn over rate, and I believe that is the ideal standard for salt water tanks.

In my XP-3 I have the stock media plus 1 box of BioMax, a filter sleeve from a Mag 350 and some phosphorous obsorbing pads. My powerhead (AC 301) supposedly flows 174 gph w/o the air injection. I'll probably pick up another (larger) powerhead today and move the 301 to my 36 bow. I like the idea of having more circulation and getting a bit of micron level filtration at the same time. Plus, for the $$ it can't be beat! I know it's not a canister, but the powerhead/filter setup will probably put me in more of a "safe zone" as far as filtration quantity goes.

I'll prolly pick up another box of BioMax as there's plenty of room in the XP-3 left.

Thanks for the responses.

PS-

:bowing: :bowing: :bowing: You win! Did you steal your setup from Shamu's tank??

Okay, so not to be beaten by this and always up for a challenge, I put the 1400litre/hour filter on the 10 litre (3g) tank. Filters the tank 140 times per hour - or the entire tank every 25 seconds. I figure I should be able to put a couple of goldfish in there now, but I may have to glue the gravel to the bottom of the tank to stop it looking like a big fluid bed filter...

You know, jokes aside, after doing this it actually worked okay and there wasn't all that much current in the tank, The filter is a resun wet/dry I got on ebay - brand new unused and cheap. The pump is a 1400lph powerhead style. Only real problem is the amount of room the pump takes up. So doesn't seem to be any overfiltering trouble even with 14000% in a 3 gallon tank

About the only other slight problem is the water level drops an inch or so when the filter starts running...

I aim for a 8x to 10x turnover rate on most of my typical set-ups (ie non-spawning, normal bio-load, planted, etc). I think you should be fine with the XP-3, but may I ask what you have against HOB filters and biowheels? I really like redundancy in filtration, so getting another XP filter might be a good way to go. If you double up on your filtration, your bio-filtration won't be affected much when you alternate cleaning your canisters.

Hey, by the way, I like your avatar, Mike. Cam Neely was one of my favourite players of all time. Awesome power forward, and set the standard by which other power forwards are measured.

You are a sick man, amosf!....but I like it.
