This video is all about closed loop flow systems. We use closed loops extensively at the coral farm, and it may be a water flow design that makes sense for your future build. In this video I want to go over what closed loops are and the pros and cons of using them.

Have you guys ever tried closed loop pumps to provide flow?
For intake strainers look into Spears foot valve strainers like this 1-1/2 version CFVS7-015. They offer a nice balance between the profile and suction dispersion.
Never used closed loop on my systems – have enough little leaks from existing bulkheads as the O-rings dry over time.
Do those L2 get hot since they arent cooled by the water?

At 04:35 what is that big red fish? Iโve never seen anything like it!
Sorry for the stupid question, but how do you use mechanical filtration on a closed loop tank?
I really appreciate this video. I've been trying to find good conclusive/informative videos of information on closed loop systems and the pros and cons for years! I wanted to try something similar on a smaller scale and see how it works out but now I'm reconsidering that as an option. It could still work, but since my largest tank is only going to be 25 to 30 gallons going with a sump or other filtration method might be more sensible for my needs.
How do you integrate the sump and skimmer?
Your facility is a true masterpiece. Thanks for informative video!
I feel like you should put black panels on those stands (magnetically attached or are those frames aluminum), that would make the room look much more professional.
Is that big red fish a hawk fish at like 4:30 in video???? If so wow that's big
i still don't understand close loop – where does the filtration goes to? i mean tank A input into a close loop pump and the pump return the same water into tank A ? where the sump
Just a heads up, Never spin grey UVPC when gluing them, that technique is used on standard white PVC pipe with a taper in the joint coupling. Doing this on grey UVPC is what causes leaks due to you pre-softening the plastic before applying the glue, the twist will cause a groves/gouges running round the joint surface (kind of like a thread) that can allow water to leak through.
What is your filtration in a closed loop?
Great video as always Than and I like info about the differences
