    Ideal chems targets to limit pH drift?

    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...

    Iron oxide--rust issue?

    Thanks again, RD. Recall that this problem is largely concentrated on 1 side of the spa that is serviced by 1 of the 2 booster pumps. This is what led to me to think I may have a rust issue in that pump. It is true that recently I'm seeing much, much smaller amounts on the other side as well...

    Iron oxide--rust issue?

    Thanks, RD. St. Charles West '87 Good question I should've thought of myself--no, it does not. But I now see from AI research that not all forms of iron oxide are magnetic so not sure what to make of that. Attached is a photo of some of it that I vacuumed out yesterday. I'm confident the...

    Iron oxide--rust issue?

    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...

    Spa rust, leak, etc.--repair vs. replace

    Thanks--this is helpful. Sadly, I have virtually no DIY skills, so repairing the issues myself is not a viable alternative. So, it's really a service provider repair vs. replace decision, but I'm struggling with lack of info on the required steps & cost to fully repair all issues and the...

    Spa rust, leak, etc.--repair vs. replace

    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...

    What is this and should I get rid of it?

    What is this and should I get rid of it?

    Yes, this seems like a good call. I'm presuming I can just get rid of this, yes? I've never seen anything like this called out as part of the TFP approach.

    It's been years.

    What is this and should I get rid of it?

    Thanks. It's weird that, while it looks like a sponge, it crumbles into tiny pieces if squeezed (or really even if touched). Not how I understood a typical scum ball to work.
