No underground filter on that tank. I found a great use for the undergravel filter on my 39 gal tank though, once I had successfully switched over the An Aqua - Clear. It's my CO2 diffuser. Ran airlines as far as I could down through the portals, 4 of them, and then attached them to a gang valve which was getting feed from my DIY still, I mean CO2 generator. I've never seen a bubble, and the plants thrive.

Maybe it is full of mulm that is dissolving into the tank. Happens a lot. Also are you feeding any spirulina tabs? They cloud the water fast if not eaten. I have a new theory on UG filters, they are great mini pallets for keeping boxes off the basement floor. More often than not they have been causing problems for people I know, trapping solid particles and releasing them as liquid waste, frustrating the growth of plants or aquarists trying to remove well rooted plants, trapping and killing fry, etc. If you don't want to tear down the tank and remove a UG filter you can dig down to the plate and clear the gravel (blowing it away with a turkey baster gets the straggler pieces) then remove the uplift tube and shove a siphon down there and try and remove the mulm. Might have to do it on both ends of the tank to get it all. It is shocking how much brown goo is usually in there after a year. Don't know if a full UG filter would result in the rest of the waste sitting on the gravel. The blood worms in a block might be a problem too, are they frozen? Some people thaw them in a cup, strain it through a net and drop the worms in the tank and flush the juice as it is full of dissolved nutrients that decompose. Or maybe they are not eating all the worms. Don't know squat about the frogs, sorry :) The crab sounds really cool though!

There are only a few other permanent residents of that tank - two monk tetras, a botia stratia, and a clown pleco. Oh, & a small red crab that shows up whenever I put in shrimp pellets. Right now 6 cherry barbs & 2 flying foxes (all very small) are being quarantined there. Other than the blood worms, I am feeding that tank flakes, and occasionally a few shrimp pellets, just to confirm that the crab is still alive. > >That tank, unlike every other tank I have, gets extremely fouled from week to week, even though I'm doing 25% water changes each week religiously.
