an undergravel filter doesnt really "filter" it just helps to rotate the water so the whole tank gets filtered....you need a cannister or HOB.....to get the chemical and bio filtration going.

actually that's not true, UGFs are very good biological filters. The good bacteria colonises on the gravel, as the oxygenated water passes through.

But they are still not very good, crap at mechanical filtration, fine particle filtration, and you have to clean the gravel just enough, but not too much.

Also if you wanna remove it you have to do like a 90% water change and take all your fish out. And it's a hassle if you wanna change tanks, move the filter etc.

Basically they are not worth it at all, even though they are a good biological filter.

Get an eheim, they rock.
 
If it's new and it wasn't cycled properly then it WILL cloud up. Oscars are very messy eaters and produce a lot of waste. A canister filter, and time will take care of your problem. Feed them less everyday or skip a day every other day until it clears. Pet fish are spoiled and don't need fed as much as they beg you to.

Let the tank be ..it will Clear let it cycle as well all will be good ;)


I agree, while your tank would benifit greatly from the addition of a cannister/power filter there is no reason why it should "fail" with an under gravel filter. I have had tanks run for years problem free with under gravel filters. Just leave it alone for a few weeks to cycle out.

Now as your fish grow you will need to add either a cannister or hang on back power filter. Your fish are gonna be very messy and you will need a filter capable of removing all the "physical" waste.

And DO NOT OVERFEED!! This is VERY important to remember. Your tank does not yet have the biological capabilities to handle a lot of waste, it will in time, but not now. If you over feed your ammonia will spike to dangerous levels and most likely make your fish sick.

Also it is a good idea to do some research. Get a couple of good books or subscribe to one of the magazines. What you will learn will be priceless!!

Enjoy the new tank!! :thumbsup:
