Remember - Level means measured level not just looks level. Ben recently posted this about a water level:

Dig to undisturbed soil to level - don't fill. A roto-tiller can help the digging.

SWCG can be a convenient source of chlorine but many of the Intex SWCGs contain a copper ionizer. Copper causes problems in pools - It can stain the pool, fingernails, light and colored hair green. It can also lead to inadequate sanitization. If you get one with a copper ionizer, I would recommend that it be removed, disconnected or defeated.

Take a look at the stickies in Pool Chemistry for Intex-type Pools, They should help.
