Curious what people use to restrict the powerful suction from the intake of there powerheads. Looking for something that will stop the powerheads from sucking up fish and inverts. I currently use foam which gets plugged up in a hurry and as a result I rarely take advantage of the true potential...

Hi there, I am currently running this skimmer on a 75 gallon as a hang on. The problem I am having is that I am not getting enough foam to collect in the collection cup. There is foam in the bottom but it never gets high enough to overflow. Not enough air? I have tried shortening and...

Thanks ccCapt. Good point. I imagine most return lines are underwater? Where exactly do you drill the hole. I understand the concept and it makes perfect sense. You mention 1" to 2" below the surface. (Or whatever level that your sump has capacity for in case of a power outrage?) Just having a...

I imagine that the box will have teeth on it. Pretty standard I think. 6x6x6 kind.

You haven't missed anything. Basically, I don't know what the **** I am doing but Im trying to figure it out. I don't see the need for a drilled return line. I don't mind piping over the back of the tank. Plus this way there is no siphoning chance. ( I know not much would siphon back). I know...

Captain, I am only going to use the one drain line. The other hole will have the elbow facing up near the absolute top where the water will never reach unless it is about to spill over the top. So my pump will be running enough to satisfy the one drain. What do you think? Asudavew - The...

Thanks Guys, You are both right. I wanted to have 2 drains only in case one got plugged. I want to play it safe. I didn't want to run both just wanted one for back up. I have decided on one drain line on a 6X6X6 box. I will put another hole as a safety in the other top corner with a street...

2 drains does make sense. In my situation, Looks like I will have a corner overflow box. My tank has plastic piece on the top of the trim across the middle which would get in the way. So for a corner overflowbox. (from the top to bottom of the tank). I will have 2 drain holes drilled. What I...

Feng Shui...I like that. I have been looking at the Durso standpipes. I think I could rig something up to work even though my drilled hole will not be at the bottom. Seems like they really help for noise. Thanks

Are sumps a lot louder than non sump set ups?

Thanks again Austinsdad, I think I will be going with the bulkhead to elbow pointing down off the back wall of the tank. I didn't even know you could glue to flex hose. I figured I would need a threaded nipple to the bulkhead which would house the flex hose by ring clamp. Would you bother...

Thanks Austinsdad. I will check out the Durso. Is this setup possible when the tank is drilled on the back and not the bottom? We are talking return line correct? And the drain line could be pvc off the overflow box to the sump?

Why flexible below and rigid up top? I like the idea of no elbows. And the ablility to change things out easier.

What type of glue?

Awesome. Thanks.

I guess I could have it drilled near the top of the tank in the overflow box. I am going to have an oversized sump tank. I have to check out some dimensions but I would make sure I have the capacity in the sump to include the lines themselves and down to the return line level in the tank...

Good point Ziggy. Perhaps not having a drilled hole for my return line would be alright. I like the fact that it can siphon back. Do you use hard piping or soft stuff for this? If I was just to get one hole drilled for drain that wasn't on the bottom, where would you suggest to be a good spot...

Hi Captain, Do many people use check valves in there return lines? I would think everybody would but it sounds like everyone just leaves for the return lines drain to the sump. Why not have a check valve or one way valve that only lets the water flow to the tank and not the sump? Does this pose...

Thanks Ziggy. Your point regarding the siphon factor for the return lines is true. In my head I had pretty much settled on having three holes drilled. I wanted my internal overflow box along the back wall in the middle. (The height of the tank). Then I was going to have 2 return lines, one in...

Thanks so much Tsoong. I am doing butt joints so if I made up a few of those jigs it will be easy. This is really going to help. I have a question about the next step, you said, : "Assuming butt joints, what I would do is glue & screw down all 4 corners of the frame. Make sure your pieces are...

Hey thanks Jsoong. Do you have any pics? I am looking for some shots of how to assemble the initial frame. Top and bottom essentially. With clamps or a square or anyway that will give me a perfect 90 degree connection. I know it seems so simple but I can't picture how the clamps would be...

Thanks for the reply Egress. Jim had also suggested using a 2x6 for the upper rails. Does this not mean the entire top rails will be 2x6? This would include the yellow end pieces. Is this correct? Also would you guys suggest a vertical brace on the back rail? If so what size? If I don't need...

What about the positioning of the two holes? (Drain and return)? One above the other? Are the holes the same size? I thought I read somewhere that the return is a little smaller. Does this have anything to do with the capacity of the return pump? Thanks again Captain. I just joined this site...

What are the advantages of having a drilled sump? Is it because of the external pumps being better? Is it a hard piping thing? Not sure if I want to drill my sump. Seems like most are drilled though. Just a cleaner set up?

Makes so much sense. I didn't know that the overflow boxes had like a baffles set up within. It's all coming together. I guess it's not really too critical where the holes are. It probably depends more on the plans for the sump setup and all the piping to go along with that. I was going to go...
