If it were my pool, I'd get some chlorine in there. You can use a submersible sump pump if you have one to circulate. If not, use a broom or something and just do the best you can. You also need to keep an eye on that pH. You don't want it to go below 7.0 because readings lower than that are acidic and can damage your pool. If you don't want to mess with the chlorine now, then don't. If it turns green, you can always get it cleaned up. Its up to you but like I said, if it were mine, I'd get some bleach in it. (I already have my pool and equipment hooked up and am chlorinating. If I don't it will start turning green pretty early in the spring as we got hot pretty early. It was mid 80s today.)
