M6S1K3 Posted March 12, 2015 Share Posted March 12, 2015 I had a 55 gallon non-drilled tank and just upgraded to a 90 gallon drilled and I was hoping one positive would be no more algae or film on the top of the water. I don't get algae anymore but I have a clear-ish/see through white layer on the top of the water. First. What is this? ( I don't have a canopy). Is it dust, algae, something I should worry about? Second. How do I fix this? To clarify. If I break the water line it separates the film. So it's somewhat solid. Thanks for the help, Farley new to the reeding lifestyle but super into it and always love to learn.

Juiceman Posted March 12, 2015 Share Posted March 12, 2015 Surface agitation will help. Point a Return or Power head towards the surface. 2 Quote Link to comment Share on other sites More sharing options...
Jimbo662 Posted March 12, 2015 Share Posted March 12, 2015 What's the level of the water in the overflow box. you want it about 1/2" below the wiers. If it's close to the water level in the tank then you're not breaking the tension that would pull the surface layer into the overflow.

Sascha D. Posted March 12, 2015 Share Posted March 12, 2015 I point a power head towards the surface of the water, towards the overflow, so that it slightly ripples. You don't want splashing. You just want it to agitate the surface. Quote Link to comment Share on other sites More sharing options...
M6S1K3 Posted March 12, 2015 Author Share Posted March 12, 2015 Ok I'll try the power head thing. And the level of the water is roughly the same. Not much of a drop in level. How would I lower it? And no I don't dose yet. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Jimbo662 Posted March 12, 2015 Share Posted March 12, 2015 Are you controlling your drain with a valve? if so, just adjust it very very slightly and let it sit for a couple of hours to see where it settles. Quote Link to comment Share on other sites More sharing options...
M6S1K3 Posted March 12, 2015 Author Share Posted March 12, 2015 Unfortunately I am not as of right now but I definitely should be ( I appreciate the replies and help). Is there another way to lower the overflow level without valves? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Jimbo662 Posted March 12, 2015 Share Posted March 12, 2015 do you just have a full siphon going down the drain? Quote Link to comment Share on other sites More sharing options...
M6S1K3 Posted March 12, 2015 Author Share Posted March 12, 2015 Yes I do Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

Juiceman Posted March 12, 2015 Share Posted March 12, 2015 OK, so yeah, your water level of the Overflow should be lower than your tank water level, I'd say either valve down your return, or put a larger pipe on the drain. Quote Link to comment Share on other sites More sharing options...
Juiceman Posted March 12, 2015 Share Posted March 12, 2015 That loop in your return hose could be your problem also Quote Link to comment Share on other sites More sharing options...
Juiceman Posted March 12, 2015 Share Posted March 12, 2015 If you can make it shorter so it's more of a direct line to the Sump, it will siphon faster and bring that level down Quote Link to comment Share on other sites More sharing options...
Juiceman Posted March 12, 2015 Share Posted March 12, 2015 And your Elbow that the water drains into looks smaller than the pipe itself. Does it have a reducer fitting on it? Quote Link to comment Share on other sites More sharing options...
Viet'spride70 Posted March 12, 2015 Share Posted March 12, 2015 Ok. So if u look that drain pipe, does it have a bigger pipe sleeves over smaller pipe that connects to a bulkhead(that can be just to get desired water level in overflow box, to reduce water noise), or just 1 solid pipe( u can make it 1/2" short) to bring down water level. And juiceman is right, u need to control a return or increase a better passage to drain, since u have 2 return that push water up faster than it drains...

Neon Reefer Posted March 12, 2015 Share Posted March 12, 2015 Also depending on what type of drain setup Simple standpipe with stockman, durso, or other your water intake may be too high. Make sure the intake is at the level you want the water level in the overflow to be. The Durso pictured below will set the water level about 1/2 up on the T fixture not at the bottom of the elbow intake. and bell type intakes like the Maggie muffler will have the water come up ~1/4 of the bell. So normally most stand pipes are a little shorter than the desired water level in the overflow box. Quote Link to comment Share on other sites More sharing options...
M6S1K3 Posted March 12, 2015 Author Share Posted March 12, 2015 Thanks all for the input. I'll give it a shot this weekend and get back to you with the result/ questions that may arise. Greatly appreciated! Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
mFrame Posted March 13, 2015 Share Posted March 13, 2015 +1 to everyone who says agitation. My tank does this. It's protein buildup and your overflow not draining quick enough to pull it down. agitate and increase your drain rate if you can. Quote Link to comment Share on other sites More sharing options...
