200 gal filter in a 180 gal tank

[DanDanUK]

I'm asuming that a filter made for a 200gal tank would be okay in a 180gal tank can anyone confirm this for me please.






P45 ? or Trust ? i know you guys really know what your on about NO DISRESPECT TO ANYONE ELSE you may know more or less than these guy's but in here these guys answer all the questions. And normally answer them correctly.

no its too small

j/p
it should be fone
what filter are you looking at?

 

[cenecker]

just my opinion - but I generally go for WAY over filtering. I.E. - if the filter is "rated" for a 100 gals I'll use it on a fifty gallon.

But then again I tend to keep too many fish in tanks so I have to go for excessive filtration

should work but remember you atleast want duble the filtration for what ever size tank.

I'm not p45 or trust but have kept a lot of tanks successfully so IMO yes, barely, esp. if you add a power head to bump up the water movement and O2. On a 150g I like 2 filters rated at 150 plus about 1/2 the bottom using an undergravel filter with powerheads. I don't think you can overfilter a tank but I KNOW you can underfilter one.

alway over filter...
never under

can't overfilter a tank, and manufacturer's "recommendations" (ie "this filter is rated for 200g tanks") are mere guidelines for the n00b crowd.

A better way to guage filtration is via water turnover per hour. You start with the tank's capacity- say, 100g, and then go from there. Most everyone aims for at LEAST 3-4x tank capacity turnover per hour (300-400 gallons per hour, assuming a 100g). Some people aim for 10x turnover... but 3x or more turnover will do the job. Actually, 1x or 2x might work for more lightly-stocked tanks, but I've never ran into anyone who's mentioned having filtration that low...
