What do you consider essential equipment? I have a decent skimmer, good lights, lots of water movement (thanks to tunze) an ATO I have not yet set up. I do not have a calcium reactor. Would you suggest a calcium reactor over a kalk stirrer?If your looking for something to add, I say a kalk stirrer is a good addition. Make sure that you have all the other essential equipment first tho.
I have a PM kalk stirrer and love the convenience of it. Like Chris said, you just set it and change the kalk out every few months. No more mixing every time you refill the reservoir or manually top-off.
The dimensions that he gave me are 9x24". I am thinking that it is probably not a newer one.I would add the kalk before you add a calcium reactor. I also would not run a calcium reactor without kalk. I also would suggest you look at a kalk reactor such as the geo reactor because it uses a maxijet for circulation rather than a stir bar. The reason being is the kalk is more than likely going to make whatever circulation pump you have fail. The mj is a simple replacement and costs no more tan $15 while many of the stir bar replacements can be extremely expensive.
In regards to the mrc reactor you specifically asked about. I would first like to know the size as they have three sizes as that may not be a good price for used equiptment. Also is it one of the newer ones that have a programable stir unit built into the unit? Those are pretty nifty. I would check the new ones out as well before you decide.
For what its worth I have a geo kalk reactor and it has yet to give me any trouble nor has it dosed any undisolved kalk. All you do to install it is place it after your ATO pump and your good to go.
Yep, a good high quality skimmer, water movement and appropriate lights are your essentials. If your keeping any echinoderms an ATO system is another big essential.What do you consider essential equipment? I have a decent skimmer, good lights, lots of water movement (thanks to tunze)...
Depending on your intended hermatype load. If SPS and clams are in your future I would recommend a calc reactor first. If your going to keep softies/sparse LPS, go with the kalk reactor. (This is with the assumption of a 50g tank or larger.)...I do not have a calcium reactor. Would you suggest a calcium reactor over a kalk stirrer?
Beautiful clam you have there!Depending on your intended hermatype load. If SPS and clams are in your future I would recommend a calc reactor first. If your going to keep softies/sparse LPS, go with the kalk reactor. (This is with the assumption of a 50g tank or larger.)
If you were running calcium reactor with a pH controller and the system were still showing a very low (consistently < 7.8 ), this wuld be an indicatin that the reactor is not correctly set or running with problems reading pH correctly by the controller. Systems that are correctly adjusted and running with a normal charge of appropriate reactor medium will have pH that runs between a range of 8.0 and 8.3 even with a heavy load of photosynthetic organisms. The problem in systems that constantly run down to the sub 8.0 range usually has to do with either failiure of the controller or with dirty or inaccuratey calibrated probes. Some brands of contollers are much worse about drifting from calibration than others, so if this seems to be a problem in a particular system, evaluating the function of the controller is ther first place to look for issuese. Other issues:To help minimize the ph swing as I have found Ca reactors can substanially lower ph. I worded my statement too strongly. I just like having the kalk to counteract the lower Ca reactor ph.
