Hi all, Before I SLAM to get rid of the other algae that's plaqued my pool, I want to properly remove the two actual spots of black spot algae. Just wanted to check I'm following the 100% right procedure. I started yesterday - at first brushed them vigorously which actually made the spot...

Hi all, In my black algae thread one person mentioned my pool shop CH levels being suspect because they were less in a second test done a few weeks afterwards, they said CH would only fall if you drained the water. Got my TF-100 test kit and tested CH, was 300. I did this twice to make sure...

I've learnt from this great forum to be very, very skeptical of pool shops and their unnecessary products. Had a look at Bunnings (big warehouse type place in Aus that sell everything including pool chemicals). Just a question out of interest - product called Pool Shine. It's 450g and the...

Hi all, The salt cell in my pool looks like it could be on its last legs - the last few weeks testing chlorine using my basic DPD test kit it has been around 1/1.50ppm (chlorinator running 6 hours a day), I'm getting a TF-100 kit sent here to Aus soon so will be able to accurately measure it...

Hi all, Have mentioned in a few other posts my SWG cell builds up calcium deposit quite quickly (the pool CH level has generally been high - on the pool shop results so grain of salt!). Anyway, I normally use a 1:8 solution of water & muriatic acid and sit it in there to clean it. Often in...

Hi, Finally found a way to get the TF-100 test kit sent here to Australia via a forwarder... can't wait to get the thing! Am pondering whether I should buy the XL refill (2 oz chlorine drops and the powder) but am not sure how long the main kit stuff would last. I have some sort of algae so...

Hi all, Great resource here helping each other - have often read it but only posting now. I have a major problem I'd be most grateful for any help with. This pool was one my late father built (structural engineer), so it has extra special meaning to me. Its a 9,200 gal / 35,000 L, SWG...
