I'd love to limit my pH drift by dropping TA to 60, as this approach was worked very well in my spa. However, I find it challenging to get the right mix of other levels in Pool Math that result in CSI around -0.15 (midway point of 0.0 to -0.3 target range). Here are my preferred targets: TA...

After many months of a leaking tub, we finally got the issue resolved in the beginning of October and, in addition to fixing the leak by replacing the circulation pump and repairing some other minor issues, we had the heater replaced, as it was heavily rusted (I've been running a Saltron Mini...

I have an Aspen Spas spa that is 9 years old, tightly encased in a 3 sided stone surround pit. I'm having multiple issues: 1) Leaks. I've had multiple leaks over the life of the spa and have been nursing a very slow one for 2.5 yrs, as pulling the spa out of its stone pit is a major...

When my spa company did a repair on the spa, they put a little green spongey cylinder in the filter tray that sits in the skimmer compartment (see photo). What is this and is there any reason I shouldn't remove it? Thanks!

I'm new to all this and could use some advice. Our handyman was powerwashing our patio and stone coping caps and I think must have accidentally sprayed under the coping and dislodged some loose grout, as 2 tiles were on the bottom of the pool the next morning. 3 issues for advice: Replacing the...

Opened the pool 3 days ago with initial TA measuring 110 (via Taylor K-2006). pH was super high, so I added (over several different dosings) 154 oz of Acid Magic. This reduced pH levels as expected per PoolMath but only dropped TA to 100 (PoolMath indicated it should drop by 21 to roughly 90)...

My pool was winterized by the last (fired) pool guy with the hole on the left in the 1st photo plugged up and with an upside down bottle of antifreeze sticking in the hole on the right (and with antifreeze mostly filling the well). I had a guy show me how to "de-winterize" the pool the other...

I'm using Natural Chemistry Instant Conditioner (liquid) and can't seem to find a clear answer here on the recommended time gap between application and testing. Everything I see is relative to solid stabilizer via the sock method. I immediately brushed the amounts on the bottom after...

I'm taking over my pool maintenance this season for the 1st time after firing my dishonest, incompetent pool guy and am preparing for opening. Opened up the filter tank to find the most disgusting black cartridge filters (as the pool guy apparently never cleaned them, despite telling me he did...

I've been using di-chlor for CYA in my spa but is there any reason I shouldn't use liquid stabilizer in scenarios where I want to take CYA from 0 to target much more quickly than via multiple di-chlor doses? Thanks

I've been using Pool Essentials 10% liquid chlorine from Lowes for the post-soak treatment of my spa but just found out that they are no longer selling it. Can't find anything comparable anywhere locally. There are some online sources that require bulk purchases at outrageous prices. Soooo...

This tube collects fine black debris in the bottom around the edges of the circle--it won't rinse out and I haven't come up with an easy way to remove it. Any ideas? Thanks

Our very old pressure-side Polaris 380 has finally kicked the bucket and I'm looking to replace it. This will be my 1st cleaner purchase, as we inherited the old one (and the pool) when we bought the house. I'm considering the P40 and the Freedom (yes, I know one is pressure-side and one is a...

Am awaiting delivery of a Saltron Mini for my spa and the online manual recommends 99.9% pure salt. I've read on other treads here that people recommend Diamond Splash Ready (99.3%) and Morton Professional Choice Pool Salt (I can't find the % anywhere, including on the Morton site). Should I...

I've owned my spa for some time but transitioned a few months back to a manual chlorine approach after my bromine-based chlorinator broke and I saw the cost to replace it. I've been having a really rough time keeping my water chemistry in order and could use some advice. In the past, I was...
