RRM method & Limewater

[madlos123]

I just read the article on how to use the RRM to dose 5 -10% of magnesium of the calcium dose.

So I have an avast marine K2 reactor and only use limewater to top off the evaporated water in my tank.

I was unsuccessful on trying to search online on the dosage. So im asking here on your knowledge.

how much ppm calcium per gallon does a saturated limewater have. So that i can add in the approximate magnesium.

I know that limewater have a reduction of potency overtime in a reactor but i just want to be in the ballpark.

I haven't tested magnesium for a while now since my test kit ran out.

Been only doing water changes about once a month or more with reef crystals salt.

Thank you

Never mind i might have found the info back in 2020.

Looks like 17 ml of randy's diy magnesium additive per 10 Liter of limewater.

Since im not using 2 part or calcium chloride. It looks like a 10:1 ratio (magnesium chloride:magnesium sulfate) per my research by randy.

So about 6.53 ml per gallon of limewater.

Let me know if thats correct or wrong

Thank you

I don't have your answer, but I wanted to say how much I love your tank. That tank looks so much like a wild reef.

What is RRM?

What is RRM?

Just say NO to magnesium testing: RMM is born

OK, this thread has been many years in the making, and I'm posting it here since folks in the chem forum are probably already tired of all the threads relating to problematic magnesium testing. I'm going to propose a method, let's call it the Randy Magnesium Method, or RMM for short. All good...

Saturated kalk is around 800mg/L calcium.

Thanks. Thats the theme. Hopefully some areas will fill in someday.
