Bonding:
Bonding a pool is installing a large guage conductor all around the pool, connected to all metal parts on and around the pool, connected to all electrical equipment ( pump / Salt Water Chloring Generator (SWCG)), and connected to the pool water. The goal is to reduce the possibility of givng someone an electric shock by making sure that there is no voltage difference between the pool and everything around it.

Most self-install storable pools make no provision for bonding. It is possible that a water leak in the pool's elelctrical equipment could enerigize the water and provide a path to ground through a person in or near the pool. Not good. It may not happen all or most of the time but the potential is there with nothing to mitigate it.

It would be safest to make a rule "No One In Or Near The Pool When It's Plugged In" and enforce it. Also make sure the pool's power supply is protected by a Ground Fault Circuit Interrupter(GFCI).

Sand Filter:
I used several different cartirdges filters from Intex and others when we had our Intex donut pools and was never really happy with the water quality - there was always some particulate that got through. The filters were working as I washed alot of goo out of them every time I cleaned them but there was still a cloudines to the water. I believe that sand will work beter and may be eaiser to maintain. Intex makes a couple different sized sand filters and other manufacturers do as well.

SWCG:
What SWCG do you have? One concern is that some Intex SWCGs have a copper ionizer included as a feature. Copper is not popular on this forum for a couple reasons 1) it can stain hair green 2) it can help control algae (which you can see) but not bacteria (which you can't see but can make you sick). On the ther hand, if you drain the pool annually, the copper may not build up enough to cause staining and if you test daily and make sure your chlorine levels are always high enough you shouldn't have a problem with bacteria.

Suggestion:
Purchase and learn to use a good DPD-FAS test kit (Taylor K-2006) - it makes pool care much eaiser - IMO. If you buy one through the link in some of this forum's moderator's signatures, the pool forum gets a few scheckels to keep the lights on.
