The alkalinity in my tank seems to be dropping steadily (about .1 dKH/day) independent of the other parameters. All parameters are tested daily because my humans are new to reefing and want to understand how everything works together.
The other parameters remain relatively steady at:
Temp: 78.1F
Salinity: 1.025
Ammonia: 0 ppm
Nitrites: 0 ppm
Nitrates: 0 ppm
Phosphates: .01 ppm
pH: 8.1
Calcium: 440 ppm
Magnesium: 1430 (+/- 15) ppm
10% Water changes bounce the alkalinity back to 7/7.1, but then it drops all over again.
My tank is about a month old. It was seeded with Arag-Alive Sand, small amount of live rock, and IO bottle bac, and cycled very quickly. There is a small microalgae bloom (looks like diatoms, cyano, or dinos…not sure). There is also coralline on several of the live rock pieces.
Tank Specs:
Tank: Fluval Evo 13.5g with stock pump and light
Filter: Filter floss, ChemiPure Blue, SeaChem Matrix
Livestock: Me (baby hermit crab)
Can anyone help my humans understand this chemistry strangeness and advise them on what to do about it?
