There is no advantage to using an UGF. They do very little in terms of filtration. I'd ditch it and stick with the HOBs if I were you.
Lol! That's right! Heheaaaand cue another 6 page thread about whether or not UG filters are worthwhile.
Search function, what's that?
Hi Diana,I tried running the RUGF (Reverse Under Gravel Filter) and even then it did not stay very clean. On cleaning day I would pump a lot of water into the 'uptubes' (Of course they are the 'down tubes' when running reversed) and blow a lot more debris into the water.
