We had a metal tray under the toaster to catch bread crumbs. Turns out this was a bad idea on a stone benchtop - bread crumbs are a lot easier to clean up than rust stains: But thanks to TFP I knew exactly what to do. Went down the Oxalic Acid route, was easiest to source at the Hardware...

Melbourne is currently dealing with an increased number of Cryptosporidium outbreaks in public pools, requiring them to close for "Hyper-Chlorination": https://www.theage.com.au/national/victoria/parasitic-gastro-like-infection-closes-pools-hospitalises-patients-20240306-p5fa83.html What does...

I can see a bright future for pool shops in space 🪐 https://www.nature.com/articles/d41586-023-01886-1

There is an inconsistency in the interpretation of the entered bleach strength between the FC-tab in PoolMath's Home overview and the Effects of Adding, that sometimes creates confusion, especially for members outside of the US. In the Home section, everything makes sense. Bleach-percentages...

I seem to have a problem with the new SWG that I bought a few months ago. Wanted to keep it out of the public forums for now until I settled potential warranty claims. Maybe a topic for @JoyfulNoise and @JamesW. Or @AUSpool and @aussieta with the local knowledge. My old Hurlcon VX7T SWG...

This morning I made my way to the kitchen, see an ant on the kitchen bench. Ignore it, have to set priorities, coffee first. Start my milk in the frother, turn the coffee machine on (one of those automatic ones where you fill in beans and press a button to get your morning fix). See another ant...

I was curious about what makes low fume MA low fume, apart from lower HCl concentrations, and looked up some data sheets to find out about the contents. One example I found was "Green Envy Muriatic Acid". In their product use, swimming pools are explicitly included. When looking into the data...

Sometimes you want to see the trend of parameters like CH, salt or CYA over time. Since they get tested less frequently, they get a bit lost in the Pool Math logs. It would be helpful to filter the logs list for individual parameters, so that you see e.g. only the logs that contain CH test...

All the CYA I ever bought looked the same, no matter where I bought it - pool store, Aldi or Bunnings. I never questioned that it could look any different, and always assumed that this is what is called "granular" CYA here on TFP (to differentiate it from "liquid" CYA). Even though I always...

Yesterday evening, my PoolMath App (Android) started to show the error message "Did your phone go swimming? We couldn't connect to the clouds, please check the weather and try again". Didn't let me proceed, message kept coming back when confirming with "Ok". Still happening this morning...

I found an interesting paper on calcium carbonate deposition on the electrodes of an electrolysis cell: https://www.sciencedirect.com/science/article/pii/S2213343720305881?via%3Dihub The paper is very recent, due for publication in the October 2020 issue of the Journal of Environmental...

Today's crop from the skimmer basket: Still alive and kicking...

I just started replying in a featured thread (Featured - How do i know if i'm generating Chlorine?), but then thought that this would go too much off-topic for the OP, and decided to start a new thread here instead. Background is the question if the SWG should be turned off during a SLAM or not...

I am following your Forum for quite a while now, but this is actually my first post. After constantly having algae problems when following standard advice on FC levels, I was very happy to learn about TFP's approach in adjusting the FC-level to the CYA-level. Having a physics background, I quite...
