Hello, with all the emphasis on higher PH , and calcium reactors (CR) often have a negative effect on PH, are CRs really needed any longer with all the dosing pump reef additives on the market that accomplish better results with higher PH to boot. Plus i have a kalk reactor now that i have been using , BUT, i also have a geo dual reactor, a carbon regulator and the Kamoer FX-STP2 WiFi Peristaltic Dosing Pump that I am not using at the moment, but dont know if i should use it as i don't want PH to lower... i am good with PH and alk currently
