My daughter just got one of those little 10X30 quick set up pools from a yard sale a couple weeks ago and did good with it for about a week but then they had to go out of town and when they came back the water was green....she was asking me what chemicals she needed to put in it to fix it and I advised her that with it being that small of a pool the best way to fix the problem would be to empty it, clean it and refill it. Am I correct? And if so what is the best way to clean something like that. She said even the hoses have green in them? She's wanting to just forget up fixing it and put it away but I told her if she would clean it up, refill it and then make sure to keep it clean it wouldn't be that hard of a thing to do, especially with a pool that small. So just asking for suggestions on the best way to clean on the green out....especially in the hoses and do you need to test and do all that with a pool that small?
