Mark Davis Posted November 6, 2009 Report Posted November 6, 2009 Do you buy baking soda or a brand-name product for Ph+? What is best for Ph-? In general, I'd like to use a system that doesn't require too much acid. I'm somewhat of a chemical freak (ie. hate them and greatly prefer anything that seems safe/natural) and am still debating many water balance / mgmt options (I will make a separate post when the spreadsheets/analysis are complete)... Regards- -mark Quote

Regards- -mark Mark, I am short of being an expert but like you hate to use all the specialized chemicals as they raise the CYA level (or total dissolved solids if you prefer) faster and make you dump and refill after 2-3 months. Use baking soda to raise pH and also raise Total Alkalinity(TA). Use BORAX to raise to raise pH but not effect a raise in TA as much. Use Muriatic acid to lower pH & TA. Try the Dychlor then bleach method to more naturally sanitize and top up with MPS (Potasium Monopersulfite) to oxidize the waste. Hope this helps, and is correct. Greg Quote
