I'm trying to get a rebar stain fixed. Contractor says that cutting out the bad stuff, versus just installing mosaic tiles over the top to cover, would have similar cost, and they're recommending the tiles rather than the real fix. Is this OK? I thought that the rusting rebar would eventually...

My SWG - an IC40 - is now in its 6th season. In past years I've been able to keep my FC level where desired by setting it 20% to 40%, depending on various stuff (if that seems low, that's probably because it's oversized for my pool at 11K gallons). When I started up this year I found that I...

This is our first cold snap with the new pool, and I'm concerned about its freeze protection. I have two pumps: the main one, a Pentair variable-speed that claims to have freeze protection (at least, it's an option in its menu), and a separate one to run the sweeper robot thingy. The Pentair is...

I have some air on the suction side of my pump. It doesn't seem to be causing any trouble, but I want to be sure that I'm not missing something. While the pump is running, there seems to always be a small air bubble at the top of the viewport - maybe a couple of tablespoons of air, if it makes...

I'd like to add Borax to my pool. The instructions here say to first get the TA into position. My pool seems not to want to budge from the range of 90-100, and I'm wondering if that slightly higher value means I should wait. A little background. The reason I want to add the Borax is probably...

Our pool is new, we just put the salt into the water. As I was learning how to use the SWG (it's a Pentair Intellichlor IC40), I noticed that this model is for pools up to 40,000 gallons. My pool is a measly 11,000 gallons. In general I'd think it would be better to have excess capacity...

I just put together a "shed" (really just a large vertical cabinet) for storing pool chemicals and equipment. But I think I read read cautions about what can be stored together (specifically, chlorine and muriatic acid, iirc), and some things that might be temperature-sensitive. If I keep my...

I'm just starting up a new pool - I've had water in it for a week now. It'll eventually be SWG, but it's not that time yet, we're still waiting for the plaster to cure. I just want to sanity-check my strategy for dealing with the water chemistry as we're getting it started. We've got a floating...

Our new pool, with light blue quartzite plaster, has rather uneven coloring. There are a couple spots of a couple square inches each, where the coloring is almost white. There are also some streaks looking like drips down the wall in two places, and some more subtle streakiness on part of the...

My new pool should be completed in about two weeks, weather depending. I'd like to be sure I get off on the right foot. I see here plenty of advice for starting an existing pool at the end of the winter. But I haven't seen any advice regarding brand new pools. And so this is my question: what's...
