Why does the level in your return sump section change so much
The grey sensor is the flood one that'll shut the ATO off or will warn me if the water level in the sump gets that high from issues such as return pump failing etc
The water level in the return pump section should be 6" so you've only really got the back wall of the return pump chamber
Sorry Gary, I didn't explain myself clearly. You'd ideally like to keep as many magnets out the water as possible. In yellow is my ATO sensor that controls the top up when the level drops. The red is the emergency shut off float. Hope that makes sense.
That's the one mate. No the flow doesn't break them up. Doesn't show it well in the picture but I have them sat in an egg crate box I made for easy removal. Also use marine pure block in place of the baffle sponge too, that does get very flakey but to be honest it is never moved and I'm not planning on moving so isn't an issue
I've only had to move them from the skimmer chamber to the initial entry chamber but it was a nightmare and took forever to move them individually so I made the egg crate basket but simply cutting the individual sides that would make up the box and that would then fit in the chamber and then pieced them together using cable ties. In theory I shouldn't ever have to move them again as they should remain in place as part of the tanks filtration, much like live rock.
You should be able to pull it away enough to fit the magnet behind there. As long as your using the tunze magnet which is sealed pretty well and you keep an eye on it you *shouldn't* come across any issues. I just have had issues with crappy magnets rusting out on me and appearing in an ICP test. Like I say, the tunze magnet is solid and as long as you keep an eye on it you should be fine.
