Kalk king kalkwasser doser

[Markcle]

Anyone else used the Kal King kalkwasser dosing system?
Just installed one on my 90g. Kong- the guy who invented this thing is very helpful, just talked me through the whole set up on his cell phone.

Just stumbled across and debating vs DIY.

Any updates? Noticeable changes? IYO worth it? Anyone else? Cons vs pros? Where did you purchase from?

Do you have any install pics? I have been looking for a better way to provide Kalk, other than the 5 gallon bucket and jbj ATO I use today.
