AquaClear Filters

Background:

So in my 29 gal I have it stocked with 4 sword tails - 3 penguine tetras - 3 cory cats -- 1 blue female gourami -- and one blak velevet angel

I have a 55 gal with a 110 aquaclear filter on it -- very happy with how clean it works ...

I also do 25% vacuum and water changed every saturday -- and rinse the sponges in aquaruim water all readings are good amm zero rite zero rate 20 in both tanks


BUT the 29 seems to get awful dirty fast -- i have loser gravel in it than in the 55 gal -- I dont know how to describe it besides sayings its looser -- the stones are a bit bigger and food and fish waste I think doesnt gte trapped in them easy -- the "junk" floats around more with the loser bigger gravel than with the smaller more tightly packed stuff in my 55gal

The meat of the question



I had a 10-30 gallon aquaclear filter on the 29 - it broke -- the motor died -- -- so i bought a bigger filter--- thinking it would take care of the "loose" stuff i always see in the 29 gal -- but no -- it didnt seem to be enough -- and it was still getting dirty fast

today - i bought a aquaclear 70 gal filter -- and hung it in the 29 along side the older filter that has been in there a few months -- and BINGO - wow -- just in a few hours the water clearned up great ....

my suspicion is that the the filter sizes on it are under rated -- in my opinion everything below the aquaclear 70 would be fine for a 10 gal and thats it .. even comparing the aquaclear 30 to the aquaclear 50 -- there is very little difference in size --

so i was curious to what you all thought about that. Are the sizes on the tank advertised on the filters to small/big?

Also, will i experience a mini cycle with the NEW aquaclear 70 while leaving the OLD aquaclear 50 in the tank.

Thanx in advance,

Paul

AC filters are the best hang on back filters IMO, but they do seem to overrate their filters as to what they can do. Like for example, an AC 50 filter is advertised for 50 gallon tanks, but I would only use it on a 20 gallon tank at the biggest. I have an AC 50 on my 30 gallon tank along with other HOBs, and I have to say, it has the most power in the smallest package. This is why I will be using 2 AC 70s on my 55 gallon tank.

yeah - I think they are great filters as well -- the rating thing kind of bugs me though -- like i said -- i have a 110 hanging on my 55gal and i think its great -- I would think the two 70's you have on your 55 would work just as well if not better

ok -- so -- so far we have 2 people who think they are rating under the the use for tank size -- maybe if we get enough who agree I can email this thread to aquaclear and they'll change the rating -- hahahaha ... erv:
probably not though huh
