Sodium carbonate (soda ash) raises pH over all common culture conditions.

It's more potent than bicarb, and that makes it a cost-effective choice for raising pH without adding excess alkalinity.

Sodium bicarbonate is the go-to reagent for many aquaculturists who want to raise pH.

But depending on the conditions of your culture water, bicarbonate will either raise pH, lower pH, or not change pH at all.

This comes up in aquaculture, aquaponics, home aquarium chemistry, & pool management.

(Spoiler alert) No, you can't manage alkalinity with aeration. This post explains why.

This post removes some of the "mystery" of moles in measures of concentration for those new to aquaculture water quality.

It includes a worked example calculation + a software tool for mole-to-mass conversions.

Aquaculture already uses a lot of ML — Manual Labor. The other ML — Machine Learning — has the potential to advance RAS.

This post is an intro to key ML vocabulary, concepts, & issues for aquaculturists.
