current: Bromine (hopefully) 3.0 PH 7.5 TA 80 CH 150 Added 10 oz Borax (17.5 ppm Borates?) I have had a devil of a time stabilizing my water. I started with tap: PH 7.5 TA 20 CH 30 I added CH first to 120. Then added baking soda to 110. Then added sodium bromide for bank. I put in 6 oz...

I have a Hayward H-Series draft induced spa heaster, 100K BTUs, natural gas model H100ID1. The heat exchanger failed. The heater is 7 years old. Should I replace the heat exchanger and thermostat myself to the tune of around $500, or replace the whole heater for about $1000? I do have one...

I know after I fill the spa, I have to balance the water and add chlorine. I'm just not sure of the order of operations. I know it is important because one thing will affect another. I will need to add a bit of calcium, TA, Borax, Chlorine bleach, CYA, and maybe some acid. What order should...

I have a chlorine spa, stabilized with 50-70ppm CYA and usually running around 3-6ppm Chlorine (bleach) with 50ppm Borates (in case I let it go, which I do sometimes -- no alge yet). I'd go bromine, but it kept poofing when we left the cover off. I keep the spa around 90-93 when not in use to...

I have a 485 gallon spa with 2 challenger Triton pumps. 1 is a 1 speed boost pump. The other is the primary 2 speed pump, which also pushes the water through the heater. It is always on, either in high speed mode when we use the spa or in low speed mode when it is just circulating. Today, we...

It seems that when I shock my pool, it looks fresh and crisp. As the FC drops to normal levels, it crosses some threshold and loses it's crisp look. I'm guessing that line is .05 HOCI, because after my pool dropped below 10ppm FC, that's when I noticed it wasn't as crisp. The spreadsheet says...

I have the same problem when my solar heater starts up. A ton of air comes out. I also get air build up in the top of my sta-rite filter tank. So each week, I open the tiny screw top and let the air out until a jet of water shoots out. I don't have any visible leaking from the solar panels...

My pool pump stopped working today. It just stopped. The case was very hot. So I turned it off, left it for an hour, and turned it back on. It's still hot, but it was running normally. The only thing I can think of is that the solar panel valve is automatic, and turns on and off based on...

I went to home depot today, to see if they carried Dichlor. Leslie's carries dichlor at $36 for 8lbs. Home Depot does not carry Dichlor. Instead, you can buy trichlor tabs, 3", 1", and trichlor "shock" granuals which includes fun additives such as Boron (borax?) and some clarifier. The 1"...

My wife left the pool cover off in a heavy rain. It added about 2 inches to the pool level. While the water is clear, FC 5.5, CC 0, and everything seems nice and clear, the water just doesn't have that "sparkle" it did before the rain. It used to look really crisp and now it seems a bit...

How do I calculate the probably amount of time it takes for all the water in my pool to theoretically go through my filter one time? I have a 15,000 gallong pool with a sta-rite 3 filter system. It says max is 125GPM. Pump is also sta-rite, 1.5HP 1.1kwatts. Also, how do I adjust this for a...

How could I estimate the amount of time it takes to send all of the water in my pool through the filter one time. I have a 15,000 gallon pool, 1.5HP (1.1kW) sta-rite pump and a Sta-Rite system 3 filter. The filter says max flow rate is 125 GPM, which I guess is gallons per minute. If the filter...
