CA2OR Posted November 15, 2009 Share Posted November 15, 2009 I am so tired of dealing with one issue after the other here. Let me explain the problem. I got this tank and sump as a set. It worked great for the guy who owned it, but I added a UV sterilizer that runs off it's own pump. Well that made the water in the sump run faster, obviously, which in turn makes the water pour in faster. Now I get crazy gurgling and a rediculous amount of microbubbles in my tank. What can I do? I have already added a second wall in the chamber where the return pulls from in an attempt to eliminate the bubbles as well as added a "slide" for the water to run down instead of splashing into there.

Rick Posted November 15, 2009 Share Posted November 15, 2009 Is ther UV sterilizer inline with the sump return? Can you cut it down to one pump? Might need to draw a picture of your current setup and then rethink the entire thing and rework it. Just depends on what you have now. (What you posted is to vague to determine the solution) Quote Link to comment Share on other sites More sharing options...
CA2OR Posted November 15, 2009 Author Share Posted November 15, 2009 No uv is not inline with return. But it does pull from the same chamber. I will try and figure out a way to describe my set up. Quote Link to comment Share on other sites More sharing options...
Rick Posted November 15, 2009 Share Posted November 15, 2009 No uv is not inline with return. But it does pull from the same chamber. I will try and figure out a way to describe my set up.So are both the sump return and the UV returning into the tank from the sump? If so then I think I would change the UV so it pulls from one side of the sump and then returns back into the other side of it rather than returning both to the tank.

CA2OR Posted November 15, 2009 Author Share Posted November 15, 2009 No Uv pulls from same chamber as return pump but dumps into first chamber where overflow dumps into. Basically anything that goes through UV goes back through my sump. Quote Link to comment Share on other sites More sharing options...

steelhead77 Posted November 15, 2009 Share Posted November 15, 2009 I ran a UV sterilizer AND a Phosban 150 reactor (both on their own pumps) in there Eric. After I figured out how to slow the water down falling into the last chamber, (PM's) I had no micro bubbles and I couldn't hear the water at all. I don't know what you could be doing so different than me to have so many problems. Try putting the hose from the UV into the last chamber and exiting into a foam sponge or filter sock. That should remove the bubbles. I had it exiting into a clump of chaeto. The flow through your UV should not be very fast. If it's creating bubbles, it's too fast (IMO). Try to describe or show some pics of your set-up. Quote Link to comment Share on other sites More sharing options...
CA2OR Posted November 15, 2009 Author Share Posted November 15, 2009 I don't think the UV is creating the Air. It did accel the water movement. I am thinking all of it is related somehow. But I don't get how the air bubbles are still able to find their way into the main display. Quote Link to comment Share on other sites More sharing options...
steelhead77 Posted November 15, 2009 Share Posted November 15, 2009 Also, if your using the same pump I was, try dialing the return back a little (close the valve a bit), this will also slow the water down. It won't take much. You can make up for the loss of flow with a Koralia or two. Quote Link to comment Share on other sites More sharing options...
CA2OR Posted November 15, 2009 Author Share Posted November 15, 2009 I did add 2 K3's. Actually that seemed to have accelerated the flow into the overflow. I know it all sounds weird. Maybe I should reduce flow and change angle of K3's. I have no idea on placement of these things. Quote Link to comment Share on other sites More sharing options...
steelhead77 Posted November 15, 2009 Share Posted November 15, 2009 Use a thick filter sponge instead of the slide. You just have to be creative and figure out how to slow the water down going into the return chamber. Quote Link to comment Share on other sites More sharing options...

Maybe I should reduce flow and change angle of K3's. I have no idea on placement of these things. 2 K3's may be a tad much for that. I had two K2's. and I had them on opposite ends pointed to the front wall so that they opposed each other and swept around the bow and created, what I thought was perfect flow.

CA2OR Posted November 15, 2009 Author Share Posted November 15, 2009 K2's huh.....hmm....maybe I need to see if I can get someone with 2 K2's to test. I might have to do a trade\downgrade. Quote Link to comment Share on other sites More sharing options...

Before you trade down try the way Scott suggested. If you do decide to trade down I have a K2 here I would be willing to swap. Quote Link to comment Share on other sites More sharing options...
CA2OR Posted November 15, 2009 Author Share Posted November 15, 2009 Cool....I just need to get 2 K2's in my possession for a day or so. Test and decide. Quote Link to comment Share on other sites More sharing options...
reef165 Posted November 15, 2009 Share Posted November 15, 2009 How many chambers is there in the sump? Why couldnt you put the supply for the UV in eather the middle chamber or just have it in the first along with the return from the UV? How many GPH is your main return? could ya run the UV inline with the return from your overflow? Quote Link to comment Share on other sites More sharing options...
CA2OR Posted November 16, 2009 Author Share Posted November 16, 2009 If I run my uv inline with the return I am gonig to have water moving through there very fast. I believe I have 5 chambers and I just split the last one to make six. I have no idea how to get a pic of it but I will try Quote Link to comment Share on other sites More sharing options...
CA2OR Posted November 16, 2009 Author Share Posted November 16, 2009 Here is a pic, sock was off skimmer return due to cleaning at the time. So basically water comes in from back right chamber, goes through wall to front right chamber with LRR, down through bubble trap, into front middle chamber with skimmer, down through another bubble trap and up through front left chamber that used to have LRR and cheato, through wall about mid way up into back chamber which houses cheato and LRR, also it is divided so the water goes in and around another wall before reaching my return pump. Also in the back chamber is the intake for the canister which pulls through my uv sterilizer and dumps into the back right chamber with the water from the overflow so that water runs through my filter again...whew...that was a mess Quote Link to comment Share on other sites More sharing options...
