Calcium and Alk low

[SABOB]

I won a bottle of Kent Marine Liquid Reactor at the last meeting in Ace's classroom.I tested my calcium (320) and Alk (6 dKH ).Have used Liquid Reactor twice,5ml 1st time and 10 ml the second time as per directions 5-10ml per 50 gallons.My pH is 8.1 My calcium and Alk readings haven't changed using API test kit.Any ideas?Not enough Liquid Reactor yet or something else?I would have thought it would have increased alittle.

I'm not familiar with liquid reactor (been MIA from the hobby for a while) but I would bet it's a better maintenance additive than it is at bumping up levels. Might want to get some turbo ca and make some home made alk with baking/washing soda mixture (google or search maast surely a recipe will turn up) to raise the levels to where they need to be and then maintain with the current stuff.
