My bro has a 90g Reef tank. Hes been struggling to get calcium to raise right now his tank is sitting at 350ppm calcium, he just did a 30 gallon water change with water that was reading 450ppm. He dosed it with some b-ionic when he did the change his tank is still sitting at 350ppm any ideas?
Ph- 8.1
dkh- 10
ammonia - 0
nitrite - 0
nitrate - 10ppm

You need to dose a calcium only supplement, such as just the calcium part of the B-ionic (not both parts), or less expensively, calcium chloride.
This article and calculator show how much and how:

Then he needs more. There is never a time when enough B-ionic calcium part alone won't raise calcium however high you want it. Check the calculator. It may need a lot more than the recommended dose on the bottle, which is intended for maintenance, not boosting values substantially. :)
