Fool me once... a comeback story

[scuglass]

Things are moving along. Got an old mag 12 hooked up over the weekend to get an idea of how everything works.

I did some calculations on the head pressure. I didnt include the manifold in these calcs.

Is this too much flow going through the sump? I find it a bit loud. Wondering if the filter socks or less flow might change things. Here's a video so you can get an idea of the noise.

Also noted some rust around the mag screws. Is this something that can be cleaned? Would anyone have concerns using it? I've heard gfo is similar to rust. I might just get rid of it or use it for salt mixing to limit the exposure.

Tagging along.

After using mag pumps at home and for work I have found them to be on the loud side and have had to deal with frequent jammed impellers for unknown reasons.

If you can afford to spend a little more on the circ pump you will be thanking yourself later.

Second what Tyler said, I only use mag pumps to mix salt would never trust one on my main system. I've gone through several return pumps from controlled to straight on/off a lot of them over time fail or get super loud on my system and have found that bang for buck with peace and quiet, the lagunas are work horses, after all even bk uses same housing block.
Also a few friends have used the fluval sea SP series return pumps with success.
