I use a Lamotte Spintouch photometer for my tanks since I got one in Oct '24. I've done tests on my 750gal setup an average of 3.6 times per week from then to present day and keep the readings in a spreadsheet.

My local reef store has a Lamotte too, it’s very cool to play with. Thank you for posting the spreadsheet. Your 750g is absolutely stunning!

Seachem Matrix is 100% pumice, according to Seachem’s own Safety Data Sheet
(Pumice 1332-09-8, EC No. 310-127-6, 100%)

The marketing claims about its denitrifying properties are misleading. In reality, it’s a poor, overpriced biological filtration medium compared to alternatives like sponge or Moving Bed Biofilm Reactors (MBBR).

'In reality' I swear by pumice. It is a great medium. Maybe the best. No micro-plastic shed into the water either.

Branded pumice might be expensive. Where do the brands get it from? Just order a sack of Lombok pumice, imported directly from Indonesia. Does not cost much.
