    I was told by someone who uses GH Booster from Greg Watson that it won't disolve unless the water is acidic.

    Therefore, one cannot add it to their RO water in their collection tank (32 gallon rubbermaid trashcan) because it just clouds and settles at the bottom.

    They said they had to add it to their tank with CO2 in the water to get it to disolve.

    Is that true?

    I planned on using GH booster in my RO water reservoir to acheive a certain GH, and I do NOT want to have to add it into my aquarium. I planned on targeting a GH/KH and then use my TDS meter to know my target TDS, that way I can mix into the reservoir in the future and just aim for that TDS without having to worry about water volumes since it's hard to know what the volumes are in a trashcan.

    THanks

    Re: Question about Barr GH Booster

    They are wrong, very very wrong.......

    No. Talk to someone else.......... fast.

    Well, I'll tell you this much, knowning the approximate volume of trash can is fine. So you can simply dose it dry directly to the tank after you do the water change without issues, I always do.

    If you are only changing 1-2 degreees, no big deal.......
    The stuff dissolves fairly slowly, so it's not a shock to the fish either.

    Tom. I added Gh booster to my RO water and it turned yellowish. Is it normal because of some Fe in it?
    What would be a start dosage for 29 galoon with a very soft RO water? One tspn would be good enough?

    Re: Question about Barr GH Booster

    I really am not sure, I've used it and never found any color changes.
    Okay, I just added 1/2 teaspoon tio a 4.5 gal RO bucket of water.
    Well, I see no color changes here.

    Not sure what to tell you.
    Seems to work without color changes.

    The mix might have a little more FeSO4 is the only thing I can figure.
    Should not make any difference though.......unless the discoloration is particularly strong.

    Re: Question about Barr GH Booster

    I added 1/2 tspn to 5 gallon of RO water. Water is not changing color immediately. I have to wait 5-10 minutes and after that I see color change. I thought the cause was FeSo4. I doubt that somebody at G. Watson added too much of FeSO4.
    I`ll try one more time and leave the bucket for 24 hours. We`ll see what happens.

    I waited an hour, I can confirm there is a slight yellow coloration.
    The FeSO4 is the only thing that would do that......

    It's probably chelated with ETDA.
    As it breaks down and is used up, that should go away.
