Awesome!!!
I took my Mini-606 the bigger version of your 404 and rigged it up. So far so good. But it is a temp job.
I pushed a threaded nipple in the end of my 606 it was a extra one I had from my Dwyer flow meter.
Zoom me and Travis talked about in the past a setup with a litermeter with my Kalk topoff also. It really is the best way to go but not right now.
Good News all!!!!!!!!!!!!!!!!!!!!!!!!!!
I will be recieving my new sump very soon

It was never a rush thing so I told that person who made it to just work on it when he gets a chance.
Lets just say this person has been in continual contact with me through the whole process of designing to progress
Ok
Next question..........
Deltec Calcium Reactors are only needed to run 12 hours a day. Per instructions... But basically it is based on the need of your tank.
I also only plan on running it for a certain amount of time since I would have Low PH issues if I were to run it all day.
Now the question..
What do I hook the timer up to?
Right now I have
Powerstrip-Plug from Milwakee controller-CO2 Soleniod plug
Where in that sequance is the proper place to but the Timer??
Also I assume I should stop the feed pump also?
I'm posting this in the Deltec forum also.
