Ill be doing a water change today and a cleaning. I'll remove the media from the sump and give it a vacuum.
The UV is a 9watt and has been turned off for the last few months - the light burn out. No changes to the NO3. Last week I replaced the light and got it turned back no and again no changes so I'll rule out the UV...

also you might want to do some googling about ceramic rings, as it appears you have a large amount of them in your sump. Alledegely they can become nitrate factorys if not maintained.

Good Point, the ceramic rings and SeaChem Matrix is gone - and sump cleaned. Before I run the coil I'll test nitrates.... Dont worry.
Well, back to the denitrate coil. Yesterday I finished all the plumbing for the "IN" side of it. Not much working room and things in there are tight. Here is a before pic. http://i101.photobucket.com/albums/m...pscbc849a8.jpg I had to use a 90degree connecter to get the bits together, but there shouldnt be 'much' water moving through this thing so... it should be good. I might hate myself for using the internal barbed connecter (even narrower and more flow restriction) much like the other 90 connecter at the bottom. Maybe I should have used the double female quick connect push connector. We will see with time. Here is an after shot & you can see some silicone - GE1 (windows/doors) just enough to keep the tubes inside from moving or shifting. http://i101.photobucket.com/albums/m...ps8b63cf5a.jpg I finished work on the top cap BUT dropped it and now I am re-JB Welding it. I think it would have been fine without more JB but I'll add just a bit more - never hurts. Pics on the next post. All thats left is to glue on the top cap, add in BIO BALLS (I'm still searching for some - Hint Hint Hint) & screw on the bottem cover. It will need 2 hoses hooked up and a week or 2 to cycle. Then we will see.

OK well here is the promised picture of the topcap. You can clearly see the 2 grey colors. That is the second batch of the JB Weld that will hold that bulkhead in place. I needed to reinforce the top cap just a bit with an extra layer of pvc.

This is pretty cool. I remember trying to make one of these way way way back in the day. Sadly it wasn't successful for me, however I still think the idea is very interesting and I'm excited to see someone succeed with it.

Done.....
OK, 'jettawagon' was kind enough to let me fill this thing with some of his surplus bioballs. THANKS!!!
Next, I glued on the top cap and tightened up the bottom access. Voilą its done! http://i101.photobucket.com/albums/m...psf47d9482.jpg I have an extra 260 gph pump sitting here so hooked it all up. I got the pump in the bucket and filled it with water. Problem, as you know we need alot of pressure to "Prime" this thing and get out all the air bubbles. I'll admit (as it wasn't working) I was fearful of a dis-assembly. After finding a large syringe, I was able to pressure infuse by hand the water that was needed into the 75' of coiled hose (inside), to prime it. After that the pump worked great and I was able to easily fill the rest of it up with tap water. It is sitting recirculating water from the bucket. With a 260gph it has a steady flow out but no pressure. http://i101.photobucket.com/albums/m...pscdc60c7a.jpg There are a few things outstanding still. The hoses leak a bit where it attaches to the denitrater, I need to get 2 hose clamps (this is easy). Also, I think that the screw on bottom cover might dribble (leak) a bit. I'll try tightening it up & if that doesn't work, silicone. I think so that I can sleep at night (fearing a leak) I'll use the silicone, but it might make it really hard to get back into - lets hope I don't need to. (I'll silicone just a bit for a seal but not the threads!) I need to open it, dry it, silicone it, let it dry/cure, ventilate it, and then I think it'll be water time again. This will be a few days & I'll save some water from the next water change to help back fill the new volume that I need. Last edited by hfp75; 10-11-2013 at 11:53 PM.
