There are a lot of kits out there but to test everything, it looks messy and cumbersome. I was wondering if there is a digital tool available that I could just drop a probe into the hot tub or pour in hot tub water into its container and the tool will do all the measurements.

My pool was built in the 60's. I have owned it for about 5 years and this year have become more involved with the pool (learning how to operate and maintain it instead of just relying on hired help). It seems the seal between the deck the and the coping is long done and was never replaced. The pool cleaning guys don't (on my second vendor) don't even tell me I need to fix this which is disappointing. I can tell the deck is no longer level with the pool with one end sinking and parting and the other end sinking a bit. I think I will replaster the pool, replace the coping, re-tile and also re-deck kind of spruce it all up in about a year maybe two. In the interim, I want to reseal things for fear water seeping in is causing cracks in my deck. Here are some pics. Tell me what you think and recommended courses of action, if any. Thanks in advance. BTW I want this to be a do it myself project. Tell me your thoughts on that as I am new to all this. I am very interested in the science and the physics of why something is done and within that context what is the best materials and procedure to take. I tend to discount the work of handymen but respect it if they have an engineering aspect behind it.
