Aqua clear advertises that if you run the filter slower the water will spend more time in the media and that will lead to more bioligical filtration. 1 AC 110 on a 180 gal. tank is not nearly enuogh Just look at the name of the filter that says it all. The reason I picked up a second for my 90 is that my LFS had a 25% off AC filters sale that was about to end who could pass up a 49 dollar 110 not me![]()
where are you from? are you in the US? if so then $49 is a lot more than you need to be spending on AC110's. you can get them from www.bigalsonline.com for $35ish and even with shipping you'll still spend less than $49. though apparently in some areas if you print out the big al's ad showing their price then some Petsmarts will price match. you'd just have to try in your area if there's a petsmart around you.
also, I think 2 AC110's on a 90 is about right. I'd run them full blast except at feeding time. I prefer to have 2 110's on my 75 and 4 each on my 125 and 150. once I get moved out again with my tanks all setup how I want though I'll probably switch to wet/drys at least on the 2 larger ones.
