Lowering alk
 

I'm filling my new tank with all brand new saltwater, and pretty sure I'll need to lower the alk before transfer everything over. I use the io reef crystal, still in the process of mixing , don't know what the alk is going to be by the time I'm done but I'll like to get my alk at 7, same as the tank I'm running at the moment...
I read about the muriatic acid and just wondering if there is another way or product to get the same result or if the acid is the easier way will like to hear it from someone that already did it or still do.
Thank you

Not aware of another product that will lower alk. I have used muratic acid in the past and it's extremely effective and easy to use.

Nowadays I just use aquaforest salt that I'd close to 7 alkaline though.

Probiotic salt?
I was looking on Amazon but didn't wanted to wait 2-4 weeks for the shipping, also if I mix with that salt I could not be able to transfer right away.... It's a nice product and eventually going to switch over slowly I guess.
Probably going to Home Depot or Rona for now and get a litre of muriatic acid .
Thank you

Shipping is more like 2-4 days, the salt is in stock. I use the AF Reef salt and my current bucket mixes at 7.4 Alk.

Ah, didn't know, 2-4 days is not bad, well is too late now for that ...also still had a bucket and 1/2 at home of the reef crystal, I kinda want to use it first then I can do a switch...
For now I just use the acid. There is a formula for the muriatic acid?

If you go to Canadian tire muriatic acid is $14 a gallon. In Langley its in aisle 53 with the paint and paint strippers.

Thanks Dunc,
Going to hd shortly....

Nothing wrong with reef crystals, I've used it for a few years now without issue. To be honest the main reason for switching salt is the AF is cheaper than RC and about the same price as IO is here, plus it's shipped to my door step.

Muriatic acid is diluted HCl.

Always add it to water and NEVER water to it.

Open the jug in a well ventilated room. Sometimes it makes smoke... don't breath the smoke.

As a precaution I add a chlorine neutralizer if I need to use the water immediately. If not I let it sit for a day or two.

I found some at Canadian tires , cause Home Depot doesn't not have the product anymore.
I was planning to fill up the tank with saltwater, measure the alk and then add the acid to get the alk at 7.
Is it safe to add the acid directly to the tank?
Is going to be nothing in the tank just some equipment, no live stock or rocks.
Going to add the acid slowly, as soon the tank is full
