so im still new to the whole tropical fish tank hobby, i can keep goldfish alive damn well. i received a 38g tank and got my cycle going but shortly after decided that i would be happier with a 55g tank. i have the 55g tank and i have built a stand for it. this is my question. i am running an aquaclear 70, it is supposed to be rated for a 70g tank, but everything ive read has said over filtration is a good thing and i was wondering what the best canister filter to get since i have an open stand and it would be nice to take the HOB( i think i used this properly) down. i was considering the eheim 2215. would that be too much or is there a better route to take?

thanks


p.s. edit. i just dont think i have the know how or experience to build a sump yet :)
 
You going to transfer the Goldie's to the 55? I would go with a 2217, instead of the 2215. Goldfish are dirty bastards and need a lot of filtration, and I would run the canister with the current HOB together. If you don't mind getting another HOB you could grab a ac110 instead of the canister but the canister is a great option.

actually the goldies are in a 20g right now and i started a tropical cycle in the 38, i plan on moving them both up 1 tank, so goldies in 38 and tropical in 55. the 20 has the aquaclear 50 on it and the 38 has the aquaclear 70 on it. my plan would be to set up a canister on the 55 and then use the aquaclear 70 on the 38. also as a note about the bacteria when starting the cycle on the 38 i ran the aquaclear 70 on the 20gallon for a bit and then used some of the water to help jump start it.
 
If I were you I'd move all the water/substrate (if you're not doing bare-bottom) up one tank level as well. You shouldn't really even have to cycle the 55 if you've got 38g of cycled water/substrate/media starting off the 55. It'd just be like a water change.

As for the canister, the bigger the better. You don't have to worry about over-filtering. If the water flow is too much you can restrict it any number of ways.
 
so something like the eheim 2215 which is for "93 gallons" would work great? and i was planning on moving the entire system up a tank level. i have addition substrate for each already waiting, just needs cleaning.
 
but back to my other question, what is an affordable way to go about canister filtration? i would like to move away from the HOB as my tank is visible from both sides.
 
The gallonage ratings on filters are pure marketing. Look for stats like the GPH (gallons per hour) turnover, as that is a more useful statistic. Of course those aren't entirely accurate, either, especially after a filter has been running for a time.

If you can afford it, I'd go with the 2217 as recommended above. I've got a 2215 and a 2217 at home and in retrospect there's no reason for the smaller filter.
 
I wouldn't really follow the "rated for xxx gallons". In my opinion the 2217 that I have right now is great and all but with its current GPH I wouldn't put it on anything bigger than a 55 by itself. It's rated for bigger tanks because the amount of media these filters hold is a lot. The 2217 should be perfect.

100% spot on. My 2217 is right now running as the backup on my drilled overflow 75.
