2 part alk precipitation

[AddictedtoSalt]

I am currently dosing Tropic Marin original balling salts for cal and alk and have noticed that part B (alk) is leaving hard white crusty crap on the end of and inside the dosing tube at the sump.
Ill try to get a pic of it later.

Any have this issue with any 2 part and is there a way to prevent it?

Its getting old cleaning the tube every week.

Is the tube in the water or does it touch the tank water?

Neither. Its at the top lip of the sump about a foot above water level

Not really sure then. That used to happen to me because when I turned off my return the water level in the sump would rise and touch the end of the tube. There would be a build up but then I moved the tube hold to another area and the problem was solved. After a long time the tube would have a white film inside but nothing that clogged the end of the tube.

Residue of part 2 from evaporation possibly

Would a check valve help with evap?

I had a check valve on it and it did the same thing.
I dont think its evap as its all over the outside of the tube at the tip
Of course I could be wrong.

How close are the tubes together? Are the supplements touching each other?

I use BRS 2 part and my alk side will crust up 2 but I do not need to clean it out. It is from the evaporation of the alk solution at the tip and the remaining soda ash is basically a salt so it builds up over time. its the same as salt creep. I set mine to run like 6 times a day with smaller amounts of alk so its flowing something every 4 hours and I never need to de crust it. it is crusty but its still open.

This plus when the dosing occurs, the drip also splashes upwards and that tends to build up. I have a crusty sump too. This is normal. lol
