What can I use to weigh down stairs going into my above ground pool? I don't want to use anything that might interfere with the chemicals.
We use several plastic-coated barbell weights ... 14 lbs or so each?
(Yeah, obviously not doing much strength-training in the hawkins3 household right now)
Check the link in my signature block. It leads to pictures and instructions on how me made our step weights. We've switched from sand in capped PVC tubes to concrete this year.
