    Precipitation/Dosing Line

    Looking for any recommendations....

    Dosing Seachem Fusion for Alkalinity & Calcium
    Dosing Lines Straight Vertical~ at least 4 inches above the water line and not really exposed to any type of water spray.
    Dosing Alk 1.6ML 6x/Day

    Still having the ALK line get precipitation buildup after a few days.

    At a loss for solving... Any recommendations for different type of product or any solution that I haven't realized that would resolve this?

    Thanks....

    There is micro bubbles in the water that rupture and cause little bits of water to fly in air and settle on equipment so if enough is happening moisture can build up.
    Also I see this on one of my systems dosing tubes from humidity under the sump and on a different system I have some splashing from emergency overflows dripping water.

    More than likely your issue is just from humidity in the area. Try placing a fan in the area to vent or push fresh air in/out the area to remove moisture build up.
    Does not take much humidity, splashing or bubbles popping to cause this.
    Another cause is just the crust that will form on the end of the tube from concentrated salts/ liquid being exposed to air and over time will build up some crust.

    I had great results with BRS mix your own stuff (exact one depends on preference and tank pH). It's super cheap and if you use half of what it says, you still have a pretty strong solution, but doesn't precipitate out in the tubes.

    You can also dilute your current stuff 1:1 with RODI and that should help as well.

    You might be an engineer if...You have no life and can prove it mathematically.

    Are you dosing them at the same time? If so separate your dosing tubes from each other.

    Separate dosing schedules that's offset. I would willing to agree either humidity, concentration, or product. Thanks for the insights....
