Hi new friends!
My fiance and I bought a house and moved in right at the end of September 2020 with a pool fully closed, in Northern Ontario, Canada, and no idea what to do! I've read and watched a lot, especially in the past couple days in anticipation for opening. Probably all of the relevant articles in pool school and some random posts from others regarding their own problems and how they fixed it. Everyone here seems very friendly and eager to offer (great) advice. I'm an analytical chemist so I have grasped the chemical side of the equation (which is a big part), but without getting my hands on it, there is still some apprehension. I've definitely been swayed to the liquid chlorine vs pucks, which is where all my initial research was dedicated too.
Because everything is all closed up, I'm not 100% sure on exact information but I can say what I know. It's a 15x24 ft oval pool, unsure of water depth but typical heights (as per google) would be around 9k gallons. The pump is a 1hp Hayward Power-Flo Matrix, Hayward Sand Master High Rate Sand Filter (1706T), and a Raypak gas heater (106).
Question time!

Question time!
- I have no idea what is waiting for me under that cover. From status of the water to what goes where and what plugs I need to take out and how to hook things up to the right places. Should I get a pool company to open for me and learn from them (I shudder to think of what they are going to try and sell me.) While I think I'm good on how to deal with the chemical side (hopefully), I won't know the technical aspects of the pool.
- On a similar note, opening kits. I know the consensus here is a no. But is a preventative algaecide on opening worth it? What about the “non-chlorine oxidizer”
- I know my water is hard because of the scale that builds everywhere, even on my countertops around my faucets. Is it worth it to get a filter for the hose when adding water into the pool? If so, what should I be looking for? I can test my tap water to get a CH value, is there a max CH that should be in the water where you shouldn't add it to the pool?
- Typical daily timeline for testing, adding chemicals, entering pool, running pump? Is this reasonable? Before swimming: test and add chlorine if req’d (run pump), enter pool at least 30 min later, test at end off day and add chlorine. If pool wasn’t used that day: test water in the evening, add daily dose of chlorine based on levels.
- Without knowing test results, I’m aware the answer to this question will be a shot in the dark but I’m hoping for an answer that will be an approximation at least. Will the refill of the pool on opening have diluted the CYA and CH levels to workable values? (*I also have no idea how much water is in the pool under the cover right now, but it’s definitely still frozen)
- I have read that an acidic filter cleaner for sand filters may be required for pools with a high CH. Considering the previous di/trichlor use as well as likely high CH in city water, how will I know if I need to use this product? I plan to deep clean it with the hose.
- How often do you add CYA? I know… test. But with backwashing, rain, and pool refills I’m just curious of how much I should buy/expect to buy over the summer. A local pool shop has a 1.75 kg bucket for $27 (CAD) but an online store has a 7kg bucket for $50 (obvi better deal but will it go bad?). Is it overkill/ underkill?
- I understand that CC is removed by direct sunlight. Is there a certain amount of time that is recommended that a solar cover should be removed per day or week? Say if we don’t use the pool for a week and it’s been covered the whole time, but LC is still added, will the CC have raised a significant amount?
- When it’s raining for multiple days straight, what is the recommended course of action? I’ve read conflicting things. Should I still test every day and add LC? Because I live in a mining & smelting town (yay for employment, nay for the acidic rain and snow), I’m almost positive it will have a detrimental effect on my pool chemistry... should I let this water fill into my pool on opening and just increase the pH/TA from there?
