It would be helpful if you considered supporting TFP so we can be here to help in the future....OK crushed up some tablets and put in a sock and tried a spot treatment. It was like a miracle! The stain gone in seconds. Totally amazing.
Nope.Thanks for all the help everyone - much appreciated. Based on these photos, does it require a clean?
Sure my pump is just a single speed though. so my question would be that I understand that running 24/7 is optimal but with cost is it ok to run it 12 hours a day? I don't believe the pool store anymore so.....So maybe the CYA is only 70. I run my system 24x7 all season. A variable speed pump lets you run and very slow speeds to still filter but electricity bill is much lower than running at full speed for a partial day.
Well it owuldn't be pure sand. it would be sand and crete mixed.Sand is more likely to wash out over time.
If everyone were successful with a sand and cement base, is everyone else just stupid to use pool crete?
SAND & PORTLAND CEMENT
The combination of sand and Portland cement is the next step up from using sand and merging the two materials will form a hard floor free of those pesky sand footprints.
Portland cement is available from your local hardware store. This is one of the more common floor bottom materials used by our DIY customers.
VERMICULITE & PORTLAND CEMENT
The other commonly used mixture is used by both DIY and even some of our pro swimming pool installers. Vermiculite & Portland cement can and should be used anytime you're concerned about ground water issues. This could be anything from having a high water table to water seepage.
Vermiculite can be purchased in 4 cubic foot (average weight 20 lbs - 30 lbs) that must be mixed with Portland cement or in 42 lbs bags that is already mixed with Portland cement.
Thank you, Yes its a hard rubber material, i found some similar manufactured by Cinderella but its no longer made
