Hello All,
Bought a new home in the Fall and I'm now a first time pool owner trying to figure out what I'm doing. We utilized the pool maintenance company the former owner used to close and then open it this spring. We've also had to call them for an issue I'll get into below. One of the first things I did was buy a WaterGuru since it seemed like the easiest way to monitor chemicals. It reports 2.5 FC (which started at 5 and is moving down over the past two weeks) and 7.6 PH. It also reports chronic low water flow around 4 or 5 gallons per minute. Not sure what it's looking for. I've sent a sample away for the more extensive test but don't have it back yet.
Pool is I think 25K gallons with 2 skimmers and a main drain. Has an attached hot tub as well. All the equipment is located behind the pool and I'll go through what I understand with pictures:

Here's the whole layout for reference. On the bottom are the automatic pool cleaners which broke a couple weeks ago and I had to call the pool maintenance people to disable so they didn't flood my neighborhood. Based on what I read on this forum I think I'm going to replace with a robotic vacuum and call it a day.

Here's the main panel. It's connected to an RS8 in the house that works fine. I was thinking of upgrading to get the App functionality but I can't seem to stop having to spend money on other parts of the pool

Here's the filter. It's a paper cartridge but that's all I know about it. They cleaned it out when they closed the pool

Here's the Heater. It's a Hayward. It's broken twice already, had to replace the igniter and the flame sensor. It works fine now but the panel always says standby whereas before it had an interface you could change with buttons. Not sure what's wrong but not messing with it for now since it works.

Next up is I'm pretty sure the chlorinator. I haven't opened it yet but from what I've read you just drop in tablets?

No clue what this thing is, if it's on, or if I want it. Looking for help.

Ditto this thing. It doesn't seem to be connected to anything but I'm not sure what it is or what I should do with it.

Spa Pump. Looks like heck but seems to run fine. Jets all blow well and no noise coming form this so I assume it can just be until it fails.

And here's why I started this thread. This is what I think is the most pressing issue, the filter pump. So when we opened the pool we noticed that it screamed like a banshee when it was on, however now that it's been running a bit it sounds more like a rock tumbler. Either way not good I assume. While looking at it I also noticed a pin hole leaked from the black part of the housing that could be repaired I think but given everything else means I should probably just get rid of the whole thing. I would like recommendations on a replacement, preferably Variable or 2 speed that I could DIY to replace. I'm pretty handy with plumbing and electric, just never owned a pool.
Sorry for the info dump but if anyone can help me with any of this I'd appreciate it. Let me know if I should post any additional info.
