Red Gracilaria and pH?

[jarviz]

I picked up a 2 small "stalks" of red gracilaria, about 2" wide and 3" tall for my 10 gallon. More for the looks than nutrient removal. I don't think this amount will even make a dent in the nutrients, but i read that it can alter the pH if it's not on reverse light cycle, due to the CO2 it releases in the dark. Is this really a cause for concern or do i need A LOT of macroaglae to really have an impact?

I have an HOB filter and powerhead so there's plenty of gas exchange if that matters.

You are probably fine

Good gas exchange is critical. Oxygen is most important, pH not so much.

One month ago, I started a 30G macro lagoon and because I have 55G stands & tanks and I liked the progress so much, I will shortly upgrade to 55G.
