Pool newbie-- possible baquasil

[medvampire]

First of all I would be concerned about the hole. I am not an expert but there are plenty here. Can you post a pic of the hole?
There is a procedure for conversation from baq to chlorine. I again am not an expert but you will find the answers here on how to.
I would recommend a good test kit. Ben sells the best here.
Most of the people here use common chemicals found at your supermarket for their pools with great results at a lower cost.
Listen to the pros here they have been there done that and will move you in the right direction.
If you go to the pool store go with a open mind and a closed wallet. This entire site is devoted to preventing us newbees from getting “pool stored”.
Read as much as you can here and at the sister web site.
Good luck
