![]() Well said Tony, just another toy if you want my opinion.
Any experienced aquarist will know when Ca levels are droping by natural factors within the reef. For example I know my Ca levels are good when the tips of both my digitata and birdsnest corals are a nice bright white, if they discolor and turn slightly grey then I know the level is dropping. Toy's are fun however ![]()
