New DIY Two Part Recipes with Higher pH Boost

Hi Randy, recently I used sodium hydroxide as a alkalinity supplement, the PH has stabilized from 8.0 to 8.2, the effect is very good, but every time there are a lot of white precipitates, so I am a little upset.

Hi Randy, recently I used sodium hydroxide as a alkalinity supplement, the PH has stabilized from 8.0 to 8.2, the effect is very good, but every time there are a lot of white precipitates, so I am a little upset.

The precipitates remain, or dissolve?

Its important to add slowly to a high flow area.

I can use the pump to blow away the sediment. If I don't use the pump, the sediment will remain for a long time，Is this a reaction?

That is precipitation. That will not redissolve.

You need to dose slower into a high flow area.

Spread out the dose and keep the pump near that area.

This is common with hydroxide dosing. I dose I to a power heard that dissolves it very quickly.

If it redissolves, it is magnesium hydroxide and that temporary formation is normal but try to mix it in faster to avoid settling of the solids.

If it doesn’t redissolve, it is calcium carbonate. You want to avoid that as it wastes the additives.

Yeah, I blew it off with a pump, and it dissolved very quickly, it should be magnesium hydroxide, but I used sodium bicarbonate before, and over time, it will have a white substance, and I guess it should be calcium carbonate, because it doesn't dissolve.Thanks for your help, Randy, so I don't have to worry anymore

Hello @Randy Holmes-Farley ,
In the version of "sodium hydroxide"
Is it necessary to add sodium sulfate for "Part 2" of Alkalinity?
If I periodically use "Balling C"...

You should NOT use the sodium sulfate recipe and Balling Part C together.

Use this recipe with Balling Part C as the third part.

Second New DIY Two Part Recipe with Higher pH Boost

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...
