Nice! I wonder how they found this so quickly??
gorgeous tank , threads like this are great. thanks for sharing. also, if you have any knowledge to throw on the automatic water change system? would love to see that.
I don't test for it, but I do 2 drops of Luigis/day.
Alk is between 7-8, Cal 400, MG 1400+, Phosphates .03 via hanna digital phosphate meter, nitrates are undetectable
How are you keeping the Mg so high?
