Carbon Dioxide acidifies the water, lowering the pH. Anything you add to raise the pH will also raise the alkalinity. As the saying goes, don't chase pH. And a pH of 8.0. is just fine. When we use to have people over (pre virus), the people breathing would drive my pH to 7.8 or so....and all was fine.
what salt do you use? should i at least switch to reef crystals for extra mag and Ca?Don't dose anything. Simply stop breathing!
what alk do u get with that?
I didn't like it because water changes caused for too high a swing in alk.....I'm a low alk user....and I don't remember, but RC was up there...12-13 or so. I do my water changes and maintain alk and calc by dosing.
thats exactly what ive been having to do, i dose 10 ml Ca and 5ml alk to get my alk between 9-10 and ph at 8.4 but it drops before my next weekly water change and alk stays the same, so im just confused at this pointI also use the purple box Instant Ocean. It's a salt that perfectly works for me. As far as my opinion on salt, it's like sauce (or as some would say, gravy)....it's more a personal preference. I don't think any one salt is "better" than any other salt. I don't know what changing to Reef Crystals would do for you, short of it now being your favorite sauce.
