High Alk Problem

t?

I use muriatic in my new salt water.. 1ml will drop dkh buy 1 per 10gallons..you must let it circulate for a day after as ph drops fast.
I have used it on display buy mixing 1ml into 1liter of ro water and slowly dosing into tank via iv bag.

Good to know. I haven't tried to use it in the display.

I've used it quite a bit in the past when I used IO. I've started using it again in H2Ocean since it seems over the years H2Ocean has higher and higher alkalinity. Locally there are no low-alkalinity salt mixes available, so muriatic acid it is. My dosing confirms the same as yours. pH does dip, but it only takes a couple hours to come back up ime.

Wow, thanks guys! This is why I love this forum...

Muriatic acid will definitely drop alkalinity but needs to be dripped slowly because it drops PH drastically.

Its essentially the same idea as kalkwasser. Its so high in PH that it needs to be dripped to raise alkalinity.

Usually at the rate of evaporation. It's not a bad idea to temporarily add it to your ATO.
