I've only ever used Aquacheck and Synergy test strips. I usually go with Aquacheck because they are cheaper and do the same thing. Synergy test strips usually come in a package with other sanitizing utilities. But, I have never had a problem with Aquacheck, they usually run like 6-7 bucks for 50 strips

Of course you can buy a new liner. There are many places even online where you can find a liner from for cheap. As for the connectors, I am pretty sure there are quite a few places as well that sell those connectors. I would check out like swimmingpoolliners.com for the liner. Its actually quite cheap for shipping considering they weigh so much. As for the walls, call their company, if they can't get you what you need they could prolly recommend something. Ive had some good experiences with them. I bought a kayak pool a few years back and they have helped me with it every step of the way.

Either way, there are still a few Kayak pool replacement part dealers. I have a Kayak that I bought in the early 90s and I have only been able to find one place with people with the knowledge to answer my questions. They are a huge online company but local to me so I may be biased, but try poolsupplies.com. Pretty sure they will have what you need. There is a guy there named like Gary or somethin with a G that helps me all the time when I call em
