Kalkwasser is soooo messy! I If your going to be dosing anyway, and I don't think the balance will be perfect with kalk (or a calcium reactor), you may as well get a doser and just do 3 part (2 part)... simple :wink:

2 part doing is all the rage, mostly because you can fine tune it exactly to your system with little hassle and there are also no undesireable side effects to deal with.

It is also has very low start up costs, and low cost maintaince if you buy bulk chemicals.

I know, I know! I really have been wanting to start up a doser but i should probably mention that I am a poor grad student who also is starting a tech company... $$$ is in short supply to say the least :razz::cry:.

I might just start doing manual two-part. Know of a good place to buy calcium chloride locally?
