Larry, there is a stickied thread (second thread from the top in the sub-forum called Pool Chemistry for Intex-type pools) that gives a very easy 'recipe' to follow when starting up a smaller pool that might be helpful to you.

As far as not being able to see the rest of the forum, you still can if you log out first. Once your registration is completed, that will no longer be necessary.

Hope you find the forum to be helpful!
