    In-ground spa aeration (not another aeration post!)

    6.6 to 8.6 in a 12 month period!! Whats being pumped into the pipes?? How often do you test your water? I suspect pH weekly? CH, CYA, salt every fortnight? Thanks!

    In-ground spa aeration (not another aeration post!)

    I feel like my pool too pauses around 7.8! I generally leave it at 7.8 unless the Aussie Gold kit reports an 8. I actually have a log book (best idea!). I generally add 2cups of acid every 3-4 days. Where as the spa needs 1/4 cup acid every second day along with some buffer. Acid pump hey...

    In-ground spa aeration (not another aeration post!)

    Hi AusPool, thanks for the prompt reply. 1. May I ask for your general CH target? I was under the impression to aim between 350-450 2. Will you add acid when your pH creeps above 7.8? I too find my pool likes to sit on 7.8. I'm not sure if I should keep adding acid to bring it down to...

    In-ground spa aeration (not another aeration post!)

    @Richard320: Do you run your spa pump daily? I've tried closing the air intake pipe and still see a number of bubbles.. Could the 280LPM pump be the culprit for the bubbles? Thanks!

    In-ground spa aeration (not another aeration post!)

    @wjr75, thanks for the prompt reply! I'll suss out if any shops in Australia sell boric acid (never heard of it before). I have tried closing the air intake ports however theres still a number of bubbles somewhere. I'm wondering if the pipe has a "built in venturi system"? Is that possible? Do...
