I tested my source water that I use to (re)fill the hot tub for ch. It tests 170. On more than one occasion, about 5 to 6 weeks after refilling the hot tub the ch tests so low that I can't test for it. I didn't know that calcium could be lowered in the water without draining and refilling...

Chemgeek, thank you for the bromine/bromide/chlorine explanation. I understand (finally!). The water seems to be ok since it cleared up (after the things I did that I mentioned above). I am testing daily right now to try to get the bromine down to 4-6. I did not understand that the cholorine...

A few more questions about chlorine/bromine/bromide... Le me see if I understand - bromine tabs dissolve and contribute to my bromide bank, chlorine converts bromide from the bank back into bromine? So the reading I get when I test is bromine. Right now I test more than 10 for bromine. Is...

Thank you for the replies. The tub is 6 mos. old. I do have a cover and it is on all the time except when using the tub. The tub is outdoors on a patio with a large elm tree growing in the center. No matter what I do a few leaves get tracked in on feet or blow in from time to time. I try...

After topping off (probably added 40 gallons, I was really low) the tests are: ph 8.2 alk 90 ch - so low the test kit doesn't appear to work (the water should turn red then add drops til blue, but my water doesn't turn red but pale yellow and drops seem to be ineffective) bromine - still above...

The hot tub was new when we got it. We ran it for four weeks then emptied and started again as we were told to. I would say the average usuage is 3 people. There are 4 of us and 2 always go out. Sometimes a 3rd and occassionally a 4th. Hard to say...it varies so from time to time. I would...

Hi, I am a newbie and I am using the 3 step bromine with bleach plan as outlined on this forum. This is the second time that after about 6 weeks of new water my water turns cloudy. The first time I thought it was because I let my bromine level drop too low and I never could get the water to...

Does anyone know if Leisure bay spas is a reputable brand? My friend has a chance to purchase 2 new "scratch & dent" Leisure baby spas (they need 2 spas) from Craig's List for less than $2500/each with only a 30 day warranty. I told her my concerns and said I would check on this for her. I am...

My husband has a small backhoe and can do the work, I believe. We are in TX. Is it easier if you stick with a simple shape such as a rectangle or oval or kidney? Or does it matter much? I looked at some that were "lagoon" style and loved them but I wasn't sure if this would be too...

We have had a 27' AG (buried 2') for over 10 years. We installed it ourselves and are very handy. We have enjoyed the pool greatly. We are moving and would like to install a diy ig vinyl pool. I have never known anyone with one and do not know much about them. I would like any opinions you...
