I'm not a true expert by any means but the pink slime (water mold) is what drove me from baquacil to chlorine due to cost, I did manage to get rid of it while still on baquacil before I switched to chlorine using the conversion process listed here on this site.....thanks to all.
some things I found out while I was going through this.
- High levels of sanitizer needs to be used and kept high to kill the bacteria.
- cause is normally due to darkness and not enough sanitizer (in my case I left the pool covered a little longer to keep the pollen off and out of the pool during spring, had a hot week, had low sanitizer, pulled cover and vola.)
- You can actually get this mold from filling your pool (alot of folks don't realize as in my case that it just needs to be dark, so you get water mold growing in your water hose while sitting on the ground, you put it in your pool, turn it on.....your pool now has water mold, you didn't have enough sanitizer to kill it and its off and growing.
- if filling with a hose, turn the hose on for about 30 - 60 seconds and remove any standing water that was in the hose before putting it in the pool.
- if you keep your pool covered so no sun can get to it, ensure the sanitizer levels are kept high, don't let them dip, its hotter under the cover, great spawning ground for germs
- water mold gets everywhere and tries to hide from sunlight, even though I killed the mold in the water i could not keep my chlorine levels high during my conversion, I found water mold that (not sure if it was dead) was in my gaskets, behind the screw holding the return, in the small clarifing tab holder, I actually turned on the little pretend waterfall built into and above the skimmer, water mold spit out, once I realized and cleaned/scrubbed these areas with a tooth brush I purchased my chlorine levels held.
