🤔 what does the air port for the hartford loop look like at the equipment pad? The spa pump spinning the water around is in a closed loop with no way to draw air in which I know we don’t want air in the pump.

Hi @mas985 . Maybe what I call the part of the Hartford loop is mistaken. The highest point of the air loop (12 ft away from spa) which I call the horseshoe had no ports or holes for atmospheric air to be sucked in. the Venturi’s are plumb in right at the discharge of the spa jet nozzles. No...

@JoyfulNoise do you have an opening on the top of your hartford loop or holes where it can draw atmospheric air in? I'm getting water jets in the spa, but no air bubbling action (its not blow out air bubbles). Hartford loop (about 12 ft away from spa with elevation of the top 1.5 ft higher...

So I spoke to the pool plumber and he said I need to drill holes or cut a slit on the top of the hartford loop to allow air to be drawn in... any one second that?

Moved from HERE Nice diagram @mas985 ! I’m going to revive this discussion since I believe I’m having the same issues 😢. I have the Hartford loop & Venturis at each spa jet discharge points (8 total, 2 on each sidewalk of 8x8 spa) im not getting the Venturi effect. No air bubbles coming out of...

I see. I used lab grade HACH total hardness testing. Which test kit specifically targets Calcium Hardness?

I used a HACH Total Hardness test kit to measure.

Total Hardness yesterday was 239 ppm. Start up guide suggests 150 mg/l min. I'm seeing on the TFP pool math app recommended 250-650, ideal: 350-550. Which is correct for new pebble plaster? Some one mentioned if the total hardness is too low, the curing plaster will leach from itself? Do I...

Thank you @ajw22 ! 3rd day im supposed to add Chlorine to the pebble plaster pool. is it recommended to use liquid bleach? Pool shock or pre-dissolved chlorine? Clorox Shock xtraBLUE ok? (directions says dont pre-dissolve though, although I read in the National Plaster Association guideline to...
