Alkalinity

[Michelle Crossley]

I seem to have brain freeze.
Could some kind sole refresh my brain on how to reduce Alkalinity naturally please

Wait. And wait some more. Or water changes with a lower alk salt than yours. Murat is acid will work also, but I would research using it in your tank before trying.

How much do you want to lower it? Water changes would be the quickest way, but quickest isn't always best. Otherwise just let the tank be and let your corals consume it until it's down to the level that you want

It is at 3.5 (10 drops). I think I will see what happens naturally.
Really don't like adding chemicals.
I have just swapped from a 3ft to a 6ft tank 2 weeks ago. Mag is also a bit high too.

Thank you. Decided to do au natural.

Good decision. I wouldn't add strong acid to a display with animals in it.

Folks do use muriatic acid (HCl) to lower alk in makeup water. So you could make a batch of saltwater, lower alk with muriatic acid, let it mix for 24 hours, then do a large water change.

At 9.8 dKh, you wont find many ASW options that mix up lower; what salt are you using? You may find that it keeps creeping higher each water change (until it reaches the levels present in the salt mix) if you don't have any/many consumers of the alkalinity present. If this is the case, reducing the alkalinity of the water change water via something like muriatic acid would be a good option to lower it to your desired levels.
