Thank you, everyone. I didn't think about putting the bicarbonate in the fridge :-D I'm up in NJ, we do occasionally have those Hazardous Waste drop off days here, I'll just keep my eyes open for them. Thank you all agsin! Great site! :)

Hello, I have some old bags of sodium bicarbonate that are hard as bricks, I'd like to get rid of them( not in the pool), but how do I safely dispose of these? I also have cal-hypo that needs to go, do I bring this stuff bAck to the pool store to have them dispose of it? Thank you for...

I would do both. Notify the health club and report it to the health dept.... chances are the health club is already aware of their water clarity situation, but are too concerned with other matters to tend to it. The health department should (and a good health inspector) will close the pool...

This is an absolute SHAME! As an operator, and director of numerous aquatic facilities, during every in-service, I remind my guards that if they cannot CLEARLY see the main drains(bottom of the pool) of the swimming pool, the pool is to be immediately closed. "If you cannot see the bottom...

Hello, JohnT, Thank you for the reply. This is not the pool with the retractable roof. This one is indoors, but has no sunlight at all. IT uses sodium hypochlorite dispenesed by an automated CAT chemical controller. THe filtration center runs 24/7. THe pool was recently shocked. CC is 0. It...

Hello, THis is such a great site, I've learned so much about pool care on here. Thank you to all of the wonderful contributors! I have an indoor pool with dull water. It is not cloudy because I can clearly see the main drains, but the water just looks "flat". It has been...

Hello, Doing a backwash today at an indoor pool, the water coming from the backwash line was soapy-like bubbly soapy. It was definitely soap because I filled a bucket with the backwash water and it was soapy...pool is hazy. ONly chemicals added ever are: sodium hypochlorite, acid magic...

Hello, everyone, Reading about ORP on another thread brought up some of my own questions. First, what is the ideal ORP range for swimming pools? The WHO says that 650mV is suitable for drinking water, than why have I seen pools with ORP setpoints at around 525mV? ANd how would you...

THank you, Jason. The pool has been sitting untouched since Friday, (I am not there nor is anyone else to check out the levels). I'm hoping that 3 days was enough to get rid of the chloramines, I guess I will find out tomorrow. Also, when using the FAS-DPD kit, should I be filing the sample...

Hello, An indoor pool had a combined chlorine reading of 1.5. The pool is 11,730 gallons. I added 1 gallon & 1qt of liquid chlorine(12.5%) to it, to bring the level up to 15ppm. The FC before shock was 1.5ppm. Well, about 15min after adding the bleach, I tested the water and the...

Hello, everyone, thank you all for the useful information, I apologize for the delay, here are the specs of this pool. I have the following: 126,500 gallon indoor swimming pool with retractable roof 3 TR140C sand filters-filled with Zeosand(just replaced a few months ago) 3 Pentair Whisper flow...

THe ceiling of the pool area is white. The pool has cleared up a little bit today. Its 36,000 gallons, so, my guess maybe a day more or so. The green tint has lightened a bit as well. Thank you, everyone. :-)

Yes, the water is not a clear green, but a hazy green...but i can see the bottom of the dep end (4ft 10in). I'm going to let the pump and filter run all night and hope it works some magic. If it is in fact metals. Would it be best for me to nuetralize the FC to 0, and add a sequestering agent?

Hello, An indoor pool that has NO exposure to sunlight was drained, and refilled, but, the water has a greenish tinge to it. The pool's liner is white. Upon filling up, the first thing added to the pool was chlorine, and large amounts. THe water was not treated with metal out or ever...

Today's readings: FC: 3.2 TC: 3.8 CC: .5 pH: 7.4 Alkalinity: 112 Calcium Hardness: 311 Cya: 0-its a commercial pool and NJ law states that you cannot use CYA in a public pool. I suspect poor circulation in these areas as well...there are no returns anywhere near where the algae is growing...

Hello, I have algae growing on my stairs, and various cracks in my pool. The FC is currently at a 2.8ppm & the TC is 3.9ppm pH: 7.4ppm This is an indoor swiming pool and the FC does not dip below 2.0ppm I treat the pool once a week with Pool Perfect-Phos Free and I see no...

Re: ZeoSand Blowing through my returns after every baclwash! Thank you for your help with this. I do rinse after I backwash each filter. I have 3 filters, each filter has its own Pentair Whisper-Flo 1.5hp pump.

Re: ZeoSand Blowing through my returns after every baclwash! THank you, Jason for the quick reply, I have 3. TR-140C filters....I am not sure of the brand of Zeosand that was put in, but, pretty much I just have to wait until all that will be crushed is crushed & blown out or just replace...

Hello, In my commercial pool, the media in the sand filters was recently (2 months ago) replaced with Zeosand. Prior to this replacement, sand was blowing through my returns after every backwash and during normal filter mode. TONS of sand at each return. It ws deemed that a broken...

Thanks, Butterfly :) Richard, I have a 150 gallon chlorine tank-it gets filled every 3 weeks.as for the CO2, I'm not sure how many pounds get filled, but, the company comes out every three weeks & fills it, I've never seen them use barrells. I will see if I have an invoice or if...

Thank you, Frustrated! :) That's a pic from when there was snow outside a few months ago; I will post a pic this weekend of what it looks like now, when the roof is open :)

Butterfly, I would love to post a picture-how do I go about doing so?

Richard, Thank you so much for your reply. :) I use sodium hypochlorite as my sanitizer. I have a chemical controller that controls the chlorine & CO2 injections. It's meausures ORP, not ppm. How would I go about measuring the amount of chemicals that are injected into the pool each...

Will do! Thank you for your help, JohnT :)

Hello, My alkalinity has been on the rise, it went from around 100ppm to 140ppm in the past few weeks. I've been adding MA on a regular basis to try to lower it, I get it down to around 100, and by the next morning, it's hovering between 120-130ppm. I wait 2 hrs after adding MA before I test...

I've been using the ColorQ for 1yr. The CH & Alkalinity tests are usually a bit off when compared to the Taylor kit. However, it is usually dead on with the FC, TC & pH. The CYA test is not accurate. A few things to watch out for with this kit. Change the test vials every 3 mnths or when...

Hello, everyone, My TA went from the low 100's (100-107ppm) to 194ppm this morning !? I test the TA everyday, so, this was a surprise. I re-tested it in different areas (pump runs 24/7), and still came up with results greater than 120ppm. The pH was a 7.4, FC: 3.06, TC: 3.23...

Thanks! I read the steps to using asorbic acid; I'm going to try using the vitamin-C tabs first since the stains are very small. Just to make sure, these are the vitamin-C tablets that are in the vitamin isle? :-x

Hello, first off, this is such a wonderful site, I've been learning so much! Thank you, everyone! :) I have some metal stains in my pool from hairclips, things like that...will vitamin C tablets help to lighten the stains or should I use something else? Where can I find these tablets? Thank...
