What parameters do most of your acro tanks sit at? Mainly concerned because I have fairly low nutrients for today’s standards. NO3 5, PO4 0.02ppm. Alk 8.6, cal 420, mag 1380, K 400A frag rack near or on the sandbed would be best. Just make sure sand is not accumulating on the frags as it will cause them to stress over time.
Frag rack par is sitting in about 280. This tank is a year old.
I don’t want to shock my recent purchases
