Baking soda is something you should easily be able to find in your home. My pH has gone down as well to almost 6. Reef Buffer™ will raise carbonate alkalinity; however, it is intended primarily for use as a buffer in a reef system where the maintenance of a pH … Use Borax to change the pH without adjusting the alkalinity. Always ensure the water coming from the reactor is properly aerated in order to reduce the amount of CO2 that actually reaches the tank, however you may need to use a pH increase chemical such as limewater or accept that your aquarium’s pH is never going to be at the high end of things and ensure the remaining conditions (calcium and carbonate alkalinity) are optimal. By adjusting the light photoperiod and intensity, you can adjust the growth level. Without Alkalinity, the water would have a tough time battling against rapid rising pH changes. Increase the surface agitation on the top of your tank to pull in more O2. People that chase pH often dose their tank much too much with a buffer that will raise the alkalinity levels too high. In order to build up a coral reef, the polyps use bicarbonate ions and calcium ions to create deposits of calcium carbonate (CaCO3 or aragonite), using energy they obtain from light through photosynthesis. When your choice for increasing alkalinity is to either add baking soda or soda ash, then that would depend on your pH, as mentioned above. To encourage coral growth, health, and metabolic processes, it’s important to remain a steady pH range within 8.1 to 8.4. Go slow here and do not exceed .5 - 1 dkh a day when raising it. You can raise the pH again by agitating the water’s surface with your pump. Raise your Reef Tank's pH by controlling Carbon Dioxide! If you grow a refugium properly with macroalgae (chaetomorpha, for example), they will quickly “eat” excess CO2 from the water. Fortunately, it’s an easy thing to fix once you understand the factors that affect pH in your tank. Another side effect of this method is that adding acids to a reef tank will cause the pH to drop.
