Calm and Kalk dosing into 720 reef tank

[cumbeje]

I have a magnus bubble dosing two-part set at 60 ml /12 times a day. Which I do not believe at all because my containers would be getting emptied pretty quick. I also have a Korallin calc reactor C4001 running also. I continue to have to add some extra Bi-carb from BRS once a week. Anyone with large reef tanks suggest a better method or I am doing okay. I keep hearing people say just add a Calc reactor and your good to go. No two-part needed. My Kalk is usually around 8.4 when tested(last week it went down below 8.0, I noticed because lose of color in corals.) Calc stays around 420. Some expert help needed! This tank has been up for 1 year now.

Sounds like your Doser is not running right. Maybe a hole in the line or something. There is no way that doing all that your doing should your numbers be dropping

yeah. But it is dosing equally. I think it's because of tube length. I am interested if anyone has been able to go to just a Calc reactor in this size tank.

Your demand seems low for 720 gallons. A calcium reactor will work just as well though. It has more to do with what your corals need though. I have a freind that runs through huge amounts of 2 part on his 300 gallon setup. The calcium reactor will be cheaper in the long run but it will lower your ph unless you have an extra effluent chamber or plumb it into the skimmer. I would think you have a co2 overabundance if your ph is low while using a Kalk reactor. Try opening some windows before you spend a was of cash.
