100 gal filtration setup???

i have a 110g tank and i use penguins bio wheel filters one 400 and one 160 and they seem to do just fine but two 400's might do great. buy them online they are way cheaper www.thatpetplace.com is where i got mine

AquaClear power filter plus Ehiem canister filter.

on my 90g i have an emperor 400 and a fluval 404. i also added a tetratech 500, that i don't trust as a main filter.

the 400 and 404 are good... the extra 500 is even better. i like massive filtration and water turnover rates. it helps keep the water clean and the maintenance down.

the minimum i would suggest would be 1 big HOB and 1 big can.

aquaclear also makes an excellent product i have been told, i just like the emperors for the spray driven bio-wheels.

edit: www.bigalsonline.com << excellent filter prices!

Sand filter and a HOB type get my nod here. My 110 is filtered by a fluval 203 feeding a sand filter. I also have a fluval 103 and a hydro-sponge sponge filter. You could also power the sand filter by the use of a power head. If you use a power head you will need a pre-filter on the intake. Aqua clear quick filters work well for this. I really like sponge filters as they are all but idiot proof. They also do a huge amount of bio filtration for their size and simplicity. I am not using a HOB as there is insufficient room behind the tank.

i would go nuts with the filters then. get the ones that turn more water per hour

i would skip the uv personally, buy a (vortex) diatom, i think you would be happier. i am still somewhat new to the hobby but haven't entirely seen the benefits of uv unless you are keeping very expensive fish....... it just doesn't seem to "do" much, and the expensive bulbs have to be replaced regularly i was told. i could see how it would help, but to me it just isn't worth the expense.

as far as flow placement, think currents...... point it towards the glass in such a way as the return path comes back towards the inlet. some sort of circular pattern seems to work best for me.... across the top, deflect off the glass and back along the bottom.

good luck

GVT, no matter what type of filtration you use you will have to do maintanence. Extreme filtration is not your answer here. Reasonable filtration with a low bioload and low feeding ( not more then once a day) will lead to a minimum of upkeep. To minimize upkeep time I would skip canisters altogether. They are a real time hog and are truly useless if not maintained. I would say go HOB as they are the easiest to clean and do upkeep on. UV is not really a filter. What it does is kills any free floating organisms. It would only really help by keeping down free floating algae aka green water. ewok I do not know if you are referring to the same filter as I am thinking about when you say " buy a (vortex) diatom", as the ones I am thinking of with that name are mostly used for polishing of the water. They clog up too fast for prolonged use.

My vote goes for two Aquaclear 500's. Cheap (right around $30), high turn over rate, easy to clean and maintain. I have two on my hundred gallon, and they keep it sparkling clean.

A little off topic, but what are the dimensions of the hundred gallon? Mine is 72 X 18 X 18, which is sort of an odd shape and I was wondering what other sizes they come in.
