Accessories & Treatments
Raise pH without feeding algae.
A pH of ~8.3 matters for the health of everything in a marine or reef tank — pH Up gets you there quickly when a reading comes back low, without the algae bloom some buffers cause.
A fix, not the fix
pH Up treats the symptom fast — but low pH usually has a cause worth tracking down.
Raises & stabilizes pH
Increases and stabilizes pH toward the ~8.3 that marine and reef aquariums need for fish and other aerobic organisms to function properly.
Won't feed algae
Designed specifically to raise pH without promoting algae growth — a common side effect of some other buffering approaches.
Check the usual suspects
Low pH is commonly caused by overstocking, poor gas exchange, insufficient water flow, or low alkalinity — worth addressing alongside the correction.
Dosing
Retest before adding more — never chase pH aggressively.
