Morning all. Trying to avoid using 3 dosing containers if I can due to space. I'm moving from ATI essential Pro (which covers everything in two containers) to classic balling. Can I combine Bicarb of soda / Carbonate of soda + Tropic Marin Part C in one bottle? Then another bottle for Calcium+Magnesium? I believe this is what ATI does, hence the two bottles.
If combining dosing containers and elements was that easy most companies would offer that option.
There’s a chemical balance i would not cut corners just for space…

Two part recipes (such as ESV) are designed using different chemicals to attain the same basic final ionic composition in the water.
Balling Part C contains a lot of sulfate and a lot of magnesium.
It cannot be combined with the alk part or else magnesium hydroxide/carbonate will preciptiate
it cannot be combined with the calcium part or else calcium sulfate will precipitate.
A two part will put sodium sulfate in the alk part and magnesium chloride in the calcium part.
Been going around in circles the last few days with chemistry and maths! I remembered that my issue with space was the reason I went with ATI in the first place. I currently have 2x2Litre ATI Pro bottles that cover everything. I can squeeze another 2-litre bottle in with a bit of a push so I can move to a DIY ALK+CAL and Tropic Marin Part C method.
I think the limiting factor and managing to squeeze enough into 2 litres to cover my usage while away for 7-10 days was Alk. I need to dose around 1.5-2dkh per day in 1300 litres. I was only looking at Sodium Carbonate and Sodium Bi-Carbonate. Then I found your recipe for using Sodium Hydroxide and believe I could use this and is possibly what ATI use to squeeze in lots of ALK to those 2-litre bottles?

The issue is I can't work out the dosing amounts. I want to base my dosing off the least soluble chemical to get as long as possible between refilling the 2-litre bottles. I'd like to create the solutions with the same strength so I can dose the same amount out of each bottle so adjustment of ALK/everything is easy and without having to re-calculate everything.
Is there any chance you could guide me in the right direction to work this all out? Thanks.

I'm not clear on exactly what you are trying to do with the DIY two part and ATI.
Two parts using bicarboante and/or carboante are solubility limited by the alk part. Hydroxide versions are not, but I'd only make it as concentrated as you really need, as you may get more and more local precipitation at the point of alk addition to the water if it is more and more concentrated.

To boost alk by 1 dKH in 100 gallons takes:
`132.5 ml diluted
26.5 undiluted
My DIY two part containing sodium hydroxide (or baked baking soda= sodium carbonate)) requires 71.4 mL to match that alk rise.
Thus, my DIY is about 1.86 times as potent as the diluted ATI Pro and 0.37 times as potent as the undiluted.
If you wanted the hydroxide solution to match the undiluted ATI potency, then you would use 71.4/26.5 = 2.7 times as much sodium hydroxide as my standard sodium hydroxide recipe.
Ok thanks, while I take that all in. I saw that these were the amount per litre to dose equally for a DIY Alk+Cal+Part C. Does that sound correct? I'm trying to figure out the equivalent for Sodium Hydroxide.
Part A - 76g calcium chloride per litre of RO.
Part B - 84g of sodium bicarbonate per litre of RO. (This differs slightly from the recipe that Tropic Marin give, as they have mixed some sodium carbonate in with the bicarbonate in part B.)
Part C - 24g of Tropic Marin Sodium Chloride Free salt per litre of RO.
I’ve been using randy’s recipe for many years and added Tropic marin’s part C 3 years ago. I also began toggling the alk additive between bicarbonate, soda ash and lye to finely tune and maintain a high; stable pH. Tropic marin’s recipe is very diluted- I would have to mix, store and dose over...

In a previous thread, I posted a true two part DIY recipe: https://www.reef2reef.com/threads/new-diy-two-part-recipes-with-higher-ph-boost.344500/ But some folks may want to just swap the new ingredient into my 2/3 part recipe (as used by BRS, for example). Here's the original recipe link...
