Do you guys discard a DI cartridge at a reading of 1 or just keep it till it goes higher?
I remember reading about DI releasing ammonia (something about binding power) first when exhausted, Any truth to that?

Thanks for your help.

what should I wait/Look for to modify my flow through it?
Thanks ...

Expect to loose 8-10 inches of height due to clearance below the stand and bracing... so assuming I have 36-37 inches of height for skimmers and equipment. Planning to use my Hurricone Cat 1 but verylikely will add any of the Sper Reef OCtopus 5000 Series and keep both if they fit.
those skimmers ...

Finally I'm starting a long waited upgrade.

A special thanks to a group of local reefers here, that already helped a lot and will for sure contribute in decisions and all aspects of the coming build.
A big thanks goes to Marc who was a great help on my last 150 Build and who provided lots of effort in a ...
