Question about hydroguard and similar

    Hi all,

    Wanna first say how helpful RIU has been - thank you all.

    Topping up my DWC res last week, I had mixed extra nutes, so I put an extra 2 gallons aside in a 5gal bucket. I had a pair of air stones going in it.

    Today, I went to pour this water into the res, and I noticed a gunky/slimy buildup on the airstones. No smell. Took a pic of the stuff floating in water too, it looked a little like phlegm.

    I'm using hydroguard; does anyone have any insight into or experience with this kind of build up on the air stones? Was there more room for whatever is in hydroguard to grow, since there werent roots in this bucket?

    Good call, going to be more careful about mixing only what I need.

    In your case, was it sitting in a bottle or being aerated? Also a little curious about what it was, but at any rate, I can just avoid it completely ha

    I had it capped in a jug with a black bag over it.

    You're in dwc. There's no difference between mixed nutes in your res and mixed nutes in a jug. Keep it aerated and it will be fine. What other nutrients are you using? I get similar gunk from Liquid Karma. I also always have a light "slime" on all my air lines and stones that are in water, but never my roots. I assumed it was the hydroguard colony of beneficials, I could be wrong.

    Good to know it's not just me!

    From your experience, this kind of gunk is okay? My guess was that it was from the bennies, too.

    I had seen light "slime" buildup in my res before, but it was more on the lines and walls, and def not as gunky and phlegmy as this backup res was.

    I'm using basically all GH (and I'm terrible at remembering what they're actually made of - still a noob!):
    GH flora micro+bloom (lucas)
    GH calmag
    Hydroguard
    GH floralicious +
    GH Koolbloom liquid

    I'd say the light slime is OK in an active res, but keep an eye on it, just in case. The floralicious+ is probably the cause of the gunk, sea kelp and humic products do it to mine.
