return line

Hey there. So I am getting back into the hobby after 40 years away. So much has changed. I have been using the BRS Facebook group and sharing my new build. I plan on doing a build thread here but before I get to that I need some advice. My display tank is a 60 gallon custom tank and I have built...

I purchased a 80w deltec UV and hard plumbed it into my return line with 3/4 pipe. However with my dc pump rated at 4000 lph was only getting around 900 lph vs around 2500lph before the uv was installed. Ok I figure a larger pump is needed. Purchased a dc pump rated at 12000 lph thinking it...

I’m getting ready to drill a tank for the first time and am trying to plan out the return line(s). It’s a 120g (4x2x2) tank and I’ve got a 1200gph rated overflow box that I’m drilling for. Is there a big advantage to drilling two return lines (3/4” ID) or should I keep it simpler and drill one...

I feel like I've been making too many boards about this project but it's my first time plumbing a system and anxiety is a huge issue. Don't want to have to redo this later so looking for some final advice before I start cutting my pipe! My system: 40g tank + 16g sump + possible addition of a...

Never seen this style of manifold in an aquarium. Is there a reason why this manifold with cold slip fittings off the 1/2” sides, a gate valve on the 1” entry and two 1” unions on the entry and exit would cause issues with a saltwater return line?

Anyone with any insight into this issue - please let me know. Just set up the new Waterbox 130.4 - did a leak test on the overflow which showed no issued and then turned on the pump. Noticed a leak between the tube and the plastic barb from the return pump hose. Of course Waterbox support is...

I’m working on finishing the plumbing on my tank and was hoping for some advice on the return line outlets. I dual have 1 inch return lines each on a separate pump. I want to have minimal plumbing in the tank and was planning on just using the bulkheads without any additional nozzles/loc...

I put this check valve and union on my return manifold, but when I attach the return line into the tank, both unions push up right against the wall of the stand. I am worried that this will cause the pipe in the overflow to leak at the hole of the overflow box. Should I be worried or should it...

I am almost done plumbing my Red Sea 170, and I built a manifold and most of the hard line for the return line. I am not sure if I should do the rest of it, to where it connects to the return pipe, with soft tubing or if I should do it all with hard pipes. Please let me know what you would do...

Hey all. I finally bought a new house, which means that I'll soon be able to set up my new 180 gallon tank. I've got everything laid out except for my return line. I'm having a really hard time finding any information on if I should drill my return into the back of the tank or use a HOB return...

Had some vinyl 3/4”ID tubing laying around at the house- plumbing 2 returns. Is there any problem with quality of me heating the tube to install into a 1 inch barb in the long run of it wearing and breaking off ??? Just want to make sure it’s durable and don’t snap off by the 1”barb stretch...

I just started a tank and my return line is dripping at a pretty constant rate and I can’t seem to get it to stop! Any suggestions?

I have a RedSea Reefer 250 and whenever I turn off the return pump to feed my fish, it creates a powerful vacuum when it sucks water back into the sump. It makes me worried about the safety of the fish in my tank since the force is enough to tear a small fish in half if it gets too close. Is...

Was thinking last night about most efficient way to plumb a return pump with 40mm output to Red Sea Reefer 25mm return pipe. Looking to minimise running cost and noise from back pressure. So, is it better to run 40mm pipe from the pump up and as far as possible then reduce down or, reduce to the...

Wondering what the proper return line configuration is for the Waterbox Marine 70.3. From the elbows on the riser there is slip female / female thread 90, male/male thread coupler with O rings on both sides, White nut, Silicone/Rubber gasket, Y discharge nozzle. The question is where does the...
