Nitrates, Phosphates and Bares...Oh MY

[andresont]

I second all of the above
get rid of foam
get rid of ceramic rings
get rid of crashed coral go Bare Bottom (BB) or get an inch or less of “oolite” sand (smallest particle size) if you can’t stand BB. The idea behind smallest sand particle size is that it will be closely packed and would keep detritus away, at the same time there is still enough space in between particles allowing bacteria to populate the substrate.
Any size larger than that and junk will seep through the sand (imagine what is trapped in crashed coral sand bed?!)

Get RO/DI water filter because your well water is loaded with dissolved solids some times up to 1500 PPM (parts per million) you want ZERO before you make you salt mix.
Filter Po4 (phosphates) out of you water using reactor (best way) or just filter media in a bag passively in the sump.
Good luck.
