Basically i got a low PH problem and the way i been dealing with it is feeding the skimmer air from outside aswell as topping off with pretty high PH water around 9-10 PH the way im getting the PH so high is by sprinkling some marine buffer by SeaChem into the RO. Now I'm worried about any side effects involving the chemistry for example having lower calcium levels or ALK levels. Just want to be smart about this.
