First, I know absolutely nothing about pools.
We were looking for just an inflatable kiddie splash pool but everywhere was sold out and....long story short we ended up with something bigger, it's a circular, 10ft x 30” tall Steel Pro Frame Pool with a PVC lining. We filled it full of water, and had a jolly time for a few days before we realised that a pool this big couldn't just be empty and refilled, we are going to need chemicals, etc, stuff to keep the water clean.
I've been doing a lot of searching online and a lot of reading here on this site, and I've gotten a fundamental grasp of the chemicals involved and stuff, but everywhere also talks about filtration systems.
So my question is, do we need a filter for our pool, or can we get along without one? This is the UK, we are having a nice summer so far but I don't anticipate being able to use it for more than a few more weeks, and we'd prefer not to have the expense if possible, given we've already spent triple what we intended just on the pool alone.
Also, is the use of chemicals affected by not running a filter?
Any and all advice would be hugely appreciated, I am really out of my depth here.
At the moment we are draining the pool because we want to dig out beneath it to make it a little more level (after filling one side settled to be about two inches lower than the other), but also because the water has gone murky after last night's rain, and the sides and bottom had a slight film, so I am going to scrub it out with some bleach, level it better, and refill it.
