From someone who is relatively new to this hobby, I thank you very much for all the tips! I am currently using a canister filter on my 55g tank but am planning to switch to a setup like this. Just curious, couldn't you put a check valve in the return line to make sure water cannot go back into the sump?

Since I am new to sumps, I have a question for you. In theory one could use an acrylic box of some type as an in tank overflow and use a pump to push the water to the sump instead of just a siphon. Do you thing that there would be problems with a sump overflow in case of a power failure?

oh and in this video it isn't covered very well on the refugium. I have since added a glass top with a light strip. So evaporation is at a minimum.

actually, I don't have to add water all that much, my tanks are covered fairly well. And the REASON it is high, is so my main tank CANNOT overflow in the event that the siphon fails. The siphon has never failed, however, if it does fail, this way, only a small amount of water can be pushed to main tank, hense, no overflowing. That is the point of having it high. There is no chance this tank can overflow if the siphon fails, or if the power goes out :)

Since your return pump is so high in the refugium, you are constantly having to add your top off water to keep the pump from sucking air. I wouldn't want to have to worry about that issue more than needed. But ty for posting the video. All in all, it was a good one.

What pump are you using for your return?

I am using an Eshopps PF-800 overflow box. No, you do NOT need to drill the tank if you use an overflow box. Drilling the tank is the other 'technique' to draining/overflowing. You can either use an overflow box, OR, drill your tank. They both fulfill the same purpose.

What overflow box are you using? Does the tank need to be drilled?

Glad I could help ;)
