constant drip rate with Ca reactor?

[Willito]

CA reactors are PITA to get working properly. I've tried every possible way without good results until I implemented a peristaltic pump. The feed to the reactor was gravity fed and the output was attached to a peristaltic pump. I formulated the amount of drops the tank required and got a non adjustable pump to match that (think it was 50ml/minute). Of course a variable speed pump (adjustable) would have been better, but thought it was too pricey at the time. With a CA reator you do need to run a ph controller to properly adjust the ph, otherwise it's a guessing game and the results become sporatic. After getting a consistant result for a year, the pump started getting noisy, too much ware on the motor 24/7. This is when I switched to 3 part dosing with a high end dosing pump. This setup was highly controllable, accurate, easy to use, and a nice piece of mind. Next to the RO/DI filters, this is the best investment for any reef requiring contant dosing. Scrap the CA reactor and join the new era of reefing, you'll see what I mean.
