OziOscar Posted September 27, 2005 Share Posted September 27, 2005 What about the possibility of putting a UGF plate behind it and having the return from the pump pushing through that? It would alleviate dead-spots in the flow and dead-spots behind the wall... Is there a detrimental effect for this? Cheers - OziOscar. Link to comment Share on other sites More sharing options...
CThompson Posted September 27, 2005 Author Share Posted September 27, 2005 Nice thought OziOscar, I have been thinking of putting sheet filter wool behind it as a biomedia, the sheet filter wool that is really tough and can be washed out time and time again. This stuff should stand the test of time, and I have been wondering how concerned I should be about dead spots and so on. Following on from your idea I could use rather than UGF, I could use UGJ. Thanks for your input - I like your idea. Craig Link to comment Share on other sites More sharing options...
Ash Posted September 27, 2005 Share Posted September 27, 2005 do you really want to be reaching behind there weekly? I'd maybe punch some holes & have powerheads behind the background with their outlet through a small hole - if you really want worry about the dead water space back there that is Link to comment Share on other sites More sharing options...

I'd maybe punch some holes & have powerheads behind the background with their outlet through a small hole - if you really want worry about the dead water space back there that is ← Why would I have to go behind there weekly Ash? If I use UGJ placed vertical behind the background, and pump water in from the outlet side of a filter (clean water), the media I am considering to put behind the background should stay clean. If I put the actual power head behind the background, then sealed the background to the wall of the tank, how do I get to the power head should it need work? I am thinking of putting a T junction on the outlet side of my filter, which I was going to do anyway so as to attach a denitrate filter. In this case, off this T junction, I put a couple of extra ones and pump water from here to behind the backgrounds, just bleeding off more water from the fist T junction. Nothing can go wrong behind the backgrounds then that I would need to gain access as there will be no moving parts. The only thing I need to take into consideration is that the water coming off this first T junction and being dispersed behind two backgrounds and the denitrate filter is clean. For this I might make an extra in line home made canister filter for that final scrubbing (for which I would use that blue fine filter wool). If anything gets through this, it won’t be held up in the media behind the background. Link to comment Share on other sites More sharing options...
