This is great info--thanks!

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...

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...

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...

Thanks, Allen

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...

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...

Anyone have any thoughts on this? Thanks

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...

OK, thanks--done

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.

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.

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!

Starting to worry about getting the new white grout to adequately color match the old grout and the old horizontal mortar. Is there some sort of "standard" grey pool mortar I should consider using the fill in the horizontal mortar cracks? And is Polyblend GroutRenew Colorant OK to use with the...

Great—thanks

Lucky you....it's a real travel destination hot spot :) Another question--I'll have to drop the water level below the skimmers for this work, so do I need to leave the filter pump off until the mortar has cured? The E-Z patch site says the grout and thinset can be submerged the day after they...

Nice to be reasonably close to home

Impressive--great school. Did they end up in the area after graduating?

OK, I now have the full plan. You've been a tremendous help...I owe you a beer the next time I'm up in Northern NJ

OK, will do. Is there a particular type/brand grout or mortar you prefer for filing those cracks or should I use that same EZ Patch 4 tile grout that you recommended for that piece?

Great--thanks. Re: the expansion joint, I pulled up a couple of the pavers, as they sit on a concrete patio, to see if there is a joint underneath. It looks like there is a roughly 1/2" gap between end of the patio concrete and the beginning of the pool concrete but it's just filled with dirt...

Thanks--very helpful. Some follow-up questions and info: How urgent are the tile repairs and the missing grout replacement? Could these wait till I drop the water to winterize in early Oct? Is there a particular type of cementitious waterproofing you recommend be applied between the thinset...
