UG filters
Hello again, this is again about my new 10 gallon. I think im going to go with a UG filter. I would like to use power heads. My question is, do I need power heads on both tubes? If not do I just put an airstone in the other tube? I wouldnt think you would just leave it open.

Thanks in advance.

a UG filter should only be your bio-logical filtration and nothing else, you should buy another filter for the mechanical and chemical

reverse flow is best for a UG

I'd be careful using a powerhead on that small of a tank. You don't want to whip them all over the place! I'd try to plug that hole. If it's open that means it'd be the easiest way for water to get to the low pressure (under the gravel) and that it won't be going through the gravel which is the point of the filter, right! :wink:

How long should one keep the UG filter on in a tank?
Mine is a 60 gallon tank and currently i keep the UG filter on 24 hours and a turbo filter on for 1-2 hrs a day...

have all filters on 24/7, there is no such thing as over filtration

If you are set on the undergravel filter then leave it on all the time. One powerhead will run the whole thing and will provide a hefty current for the fish. As long as you do regular gravel vacs and take the time every 6 months or so to clean out under the filter plates it can run clean for a long time.

If you run another filter then run the UGF in reverse. Still works fine for biological filtration and relieves the need for cleaning under the plates. A prefilter on the powerhead will keep debris out from under the plates.

Is there any specific reason you want to use the UGF? Many think that they are not worth the hastle and HOB filters will provide more than enough filtration. That and if you want to go planted some day, UGF are not the best to have.

The reason I am thinkging of a UG filter is because I am going to be putting GBR in the tank and I am also going to be putting a Penguin filter on the back. I just thought that it would be a good idea with rams being picky about water params.

Can anyone explain me wot exactyis reverse UG filteration and how do i carry it out(along with the additional equipment i might need if any)

You can set most power heads to either suck water down through the gravel and then blow out the top of the tube into the tank or suck water in from the top and blow it down under the gravel and up through it. The second way would be reverse undergravel filtering.

reverse flow is what its called. It uses the same method as a normal flow but doesnt use the mechanical part. You pretty much set it up the same way as a normal one except you need to buy a reverse flow powerhead with a sponge pre-filter. The powerhead instead of sucking water out of the intake tube, it pushes water into it which in the end comes out of your gravel. It provides only bio-logical filtration and nothing else but it is much better than a normal flow as there wont be any gunk stuck underneath the filter plates.
