I have been using Seachem Reef Salt doing 15 - 18 gallon water changes weekly on my 125 gallon mixed reef tank.
The calcium seems to hover around 480 to 490 without any dosing other than water changes. Is this level acceptable?
My alkalinity is fine was well as my magnesium.
I have two brain corals, two montiopora capricornous, one green birdsnest coral, one montiopora encrusting, one goniopora, two 6 to 8 inch red rose bubble tips which used to be one 12 inch for 22 months until it split into two with a pair of continuously breeding Tomato clowns laying eggs on the rock next to them, one 14 inch green bubble tip, on six inch bubble tip, two groves of palythoa polyps one 12 inch coverage and the other six inch coverage, two maxima clams and two crocea clams doing fantastic opening with their mantels in the current, various mushrooms including red, green, blue, and maroon.
