Update: I've been worried about the Apex, and because I run a classic with the international EB6, I don't have that many options for new accessories. I was on the fence about going controller-free, or getting a 2016 apex brain to have as a spare, but in the event something happens to my apex, I don't think replacing it with another apex is much of a fix.
In light of this, I have ordered a GHL Profilux 4e with three of the new Powerbar 6.1e. Will probably be 4-6 weeks before it arrives and I have a chance to set it up.
Aside from this, the reef is really growing. I'm going through about 1/2 cup of calcium reactor media a week as well as replacing all evaporated water with saturated kalkwasser. I will post some photos later in the week.
Kalk is dosed via the same kind of dosing pump I use for the calcium reactor - IKS Vario Blue 2. It is set to run with a few conditions: only when the calcium reactor isn't working (ie between 8pm and 10am), and only if the display's pH is < 8.5, and then it is controlled by several level switches. It is also restricted to run for 30 seconds 10x an hour. So there is very little chance of danger.
I see, so you control the IKS doser currently with the apex and it is basically operating on/off cycle of the dosing pump? I'm setting up kalkwasser dosing as well, however i just got an single dosing pump to do the job. Now I'm pondering, how to add some safety controls to it. Your tank looking gorgeous, as usual.
Thanks. I’m going to use the Tunze 3155 osmolator with its switchable socket to control the IKS and then the ghl will be a backup control to that. Lots of options out there for the control required. If you’re going to use kalk, best to have some protections in place. I don’t use a stirrer, I just dose from a large container.
You could also dose a set volume of kalk per day (less than daily evaporation) and then run a freshwater ato separately.
