Calcium Blockage in Auto Dosing Line

[littlebigreef]

How do other people deal with this?

The specifics; product is B-Ionic 2-part with Mg being dosed from a third reservoir. Hardware is a Jebao 3 channel dosing unit with the lines run through a wall and out to the display where they sit just barely in the water above the return nozzle. I previously had the lines dumping into the sump around the return pump but I found I was just growing coraline algae in the sump.

I'm at the point where I'm running a long thin screw driver into the tip of the calcium line every few days to keep it clear (this after a clog in August led to a nasty alk swing). I can live with this if I have to but I'm curious, does keeping the line out of the water reduce the likelihood of an obstruction?

Is it time to break out my Knop calcium reactor? I am a fan of B-Ionic and would like to continue using their product if possible.

Absolutely keep the discharge line above the sump water level. This will substantially reduce buildup. Additionally, make sure to space out the dosing times between part A & B by many minutes.

I agree you need too keep the lines out of the water ..

Yup, this. Optimally, they should be above the water line even when your return pump is off and you're doing maintenance. Otherwise you'll get precipitate in both the calcium and alk lines.

Alright, I had a feeling it would be as simple as that.

It would be really nifty if someone designed an attachment to tie the dosing line into the return nozzle for applications where you're dosing directly into the DT. I may follow up here with what I decide to do.

I just have my additives dose in the final chamber of the sump. Goes directly to the DT.
