Dosing Alk/cal question.

[Psychonaut]

So I just started dosing and I tracked my alk drop over 7 days and it went from 9.6 to like 8.8 over that span. I have the BRS pharma pouch for both alk and calcium. The problem is I lost my cal test kit, so I don’t know exactly how much calc was consumed

So forgive me if the the numbers on that don’t add up 100% I was just estimating, but the long and short of it is that I should be dosing 20ml of alk per day.

Everyone says dose alk and calc equally but.... it can’t just be that easy right? Nothing in this hobby is easy lol... can I really just assume that if I just dose 20ml calcium per day, on opposite hours of alk, things will stay in balance?

Probably 99% of the people that use 2-part add equal amounts of each. The remaining 1% run stuff like sulfur reactors and have to dose much more alk than calcium. Unless you actually test you’re left with assuming that equal dosing will keep things in balance .... which they probably will.

The proportions of calcium and alkalinity are likely to remain in balance. But the final figure may fall or rise, it depends on your system requirements.
You will definitely need a test kit.

You're having less than .1 dkh drop per day - 20ml per day seems extremely high unless your tank is 300+ gallons I have a .2 dkh drop a day and I dose 3ml total

I do 20 ml of both ever other day stay right where needs to be. I thought the same thing when I started doseing but nope it's just that easy

Make sure you try the calculator

20ml a day would be supplementing a HUGE alk drop.
