There seems to be a lot of questions recently about pools. Generally speaking, are these considered on-topic for the site? Or is it a matter of specifics?
My thoughts are that questions about pool care (ie: quantities of chemicals to use, how often to run a pump) should be off topic but questions like "How can I install my own heater" (just made that up, not a specific example) should be considered on-topic as they are DIY.
