Mystery of Sediment Upon Opening

It may not have been mixed well enough or 0 FC rain runoff sat there festering until your next chlorine add / mixing. Im not saying it has to be algae, just that it usually is and the OCLT (which you're doing
) is the first step for all filtering or sediment issues. It could also be pollen which is now being stirred up when it wasn't, which just so happens to hit about the time you feel you should open. It would also explain why it goes away on its own in a few weeks, with no other effort devoted to it.
If the pipes are expelling organics you will fail the OCLT. (Slam will probably fix it)
If the pool has algae you will fail the OCLT (slam definitely will fix it)
Or its pollen and we wait it out.

With the Blower On, both ports are negative pressure (Vacuum or below atmospheric).
With the gas valve closed, the gas port has a more negative pressure than the vent port, which results in a positive reading even though both ports are vacuum.
This is because the gas port is closer to the blower impeller/fan.
This reading is not gas pressure.
With the gas valve open, the vent port has a more negative pressure than the gas port, which results in a negative reading even though both ports are vacuum.
This is caused by the gas pressure pushing the gas port pressure higher than the vent port pressure.
This is also not the actual gas pressure. It is a pressure differential between the gas port and the vent port.

Fiberglass Pool Chemistry

Unless you have waterline tile or piece of equipment that mandates a minimum CH, you generally don't need to add calcium. The gelcoat doesn't have plaster properties, so any calcium is simply a small preventative measure to help against certain types of potential staining. The TFP recommended levels are just fine.
You can test it, but I suspect the chalkiness you are experiencing is probably not calcium. Some might classify it as related to oxidation, or perhaps just the effects of the gelcoat reacting to chlorinated water. It doesn't happen to all FG pools, but it is quite common. Below is my experience.

Skimmer basket replacement surprise
- By Jmen

Our skimmer baskets have become brittle and needed replacement after 25 years here. The bottom of the existing skimmers have marking “Model SP-1082, SP-1084” (bottom pic above)
A Hayward basket was found online indicating “Hayward Basket, Oem, Sp1082/1083/1084/1085/1086 Skimmer”, so a couple were ordered. However, what arrived had a round opening at the bottom of the basket. (Top pic above)
The opening appears to be for a perforated pipe “riser”. That’s fine, but the packaging did not include risers and I can’t seem to find them available separately online. Any suggestions where to order the skimmer risers separately, or what pipe fitting might allow me to create my own riser is appreciated.
Thank you,

You can perform some diagnostics on it to see if it is heating, examine it visually, check its resistance, which should be 60 ohms +/- 20 ohms.
Check that 120V AC is going to the igniter when the heater starts.
A new igniter resistance is 40 to 80 ohms.
The igniter is about 450 watts, which is about 3.75 amps at 120 volts.
