Tunze Comline calcium reactor

[New Reefer]

Hi.

I'm in the process of setting up an old Comline Ca reactor (no model number visible on the unit...) which I've purchased second hand a while ago, and I would really appreciate it if you could assist with some advice.

1. This unit does not appear to have any water inlet or effluent outlet, other than some slots in the one side of the unit. Am I correct in assuming that this unit works on the same principle of diffusion as does the Comline protein skimmers?

2. The CO2 inlet tube (entering the unit through the top, and running down to a venturi connection on the circulation pump) appears to be leaking gas just below the clear plastic top (housing the screw-on refill lid). Is this as it should be? I would have thought that all the gas should be sucked into the pump's venturi, but hopefully I'm mistaken...

Regards,
Hennie

I believe on that model it worked on passive diffusion, it was a poor performer to be honest, the new model has an effluent outlet and is more adequate.

On that unit, it has been sometime since I worked with one but the CO2 went in under the lid and then was picked up by an intake to the venturi in the highest corner, the plate will be at an angle with one corner higher than all others. I would not expect this reactor to handle much of a heavy load.

Thanks, Roger.

Just to make sure that I understand, the plate running at an angle (with the screw-on lid) should be at the top, and the pump at the bottom - is this correct?

Some bubbles are forming directly below the slanting plate - it appears as if the tube is leaking close to the slanting plate. If this should not be so, I will have to try and seal it, or just re-route the CO2 supply tube along the outside of the unit and feed it directly into the pump's venturi. Would this be OK?

Regarding the "light load" - I'm prepared to give it a try... I'm also dripping Kalk, and have managed to keep some very nice corals for some 6 years now without any calcium reactor, so even a small increase in calcium would be OK.

The CO2 should come out right under the plate, their is a venturi intake seperately that picks up the gas that is added as well as recirculated from the high corner. The pump goes at the bottom.

Thanks for the help.
