Maintaining Alkalinity With a larger setup, I ditched my usual practice of using dosing since it’s too troublesome and costly to sustain the dosing. Therefore I invested in a big ass Calcium Reactor from Skimz, CM202. Lucky I still managed to squeeze it into my sump. First time using a CR and really big thanks to Heng and Leon who has been sharing with me useful tips to install and manage this set of equipment. So let’s talk about the whole setup and hopefully Reefers who are thinking about installing a CR, instead of a dosing pump, can find some useful information here. Essentially, a CR uses carbon dioxide, that forms carbonic acid, to melt the calcium media at a regulated rate. This in turns releases a balanced portion of dkh and calcium into the tank which helps you maintain 2/3 of your big 3 parameters at the same time. Of cuz, you will need a CO2 canister and a Solenoid to regulate the discharge of CO2 to maintain the ph at the right acidity, usually 6.5-6.8. (By the way, any lower, you will risk melting the pump components) I chose the Art Pro Series which looks pretty sleek and easy to use. You will also need a ph controller to help you cut the power of the Solenoid when the ph is out of range. For this, I am using APEX which I will share more on subsequent post. Btw, I ditched the bubble counter (which helps you visually track the rate of CO2 release into the reactor) since CM202 already has a bubble counter. If you look at the picture of the Solenoid and Canister below, the right gauge shows you the remaining CO2 in the canister and left gauge shows the pressure which I set at around 20psi. Big knob controls pressure and small metal knob by the side controls the amount of CO2 released. Here’s the complicated tubes on top on my CR. Just glad that Heng set up everything for me nicely. In case you are wondering what is the small chamber of coral chips for, it’s to increase the PH of the water before it goes into the tank. But having a CR definitely will lower the PH of your tank. My lowest is currently at 7.86 but it’s bound to lower further as my uptake gets higher with more livestock. Have been also figuring out how to keep it higher or closer to 8.3. Most common methods are to reduce the CO2 in your tank water, other than hoping my chaeto take up more CO2 at night (as I run it reverse light period) I am also trying prevent my skimmer taking air only within my tank cabinet/fish room, by running a hose that pulls air from my living room directly to one of my skimmer air intake. Will share again if this keeps increase my ph. Sent from my iPhone using Tapatalk
