First post on this forum, apologies if the details, terminology or etiquette are not spot on. No offense is intended!
I have a scale issue, a big one.
History skip this if you are easily bored
My pb completed and filled my pool back in March. When the pool was full I called them to come and do the start up and got no response, for over a week. 9 days after the pool had filled a chap turned up, switched the filter pump on threw some salt and muriatic in the pool along with the cleaner, shook my hand, wished me luck and was gone! Total time on site less than 15 mins. At this point let me state I am a complete newbie at this - never owned a pool before.
My local pool store have been fairly good at getting me started CYA, more acid & pool perfect recommended and added within the week. However they also got me into the nasty habit of "run a test with these strips every week and then bring us in a sample of your pool water once a month - we'll see you straight"
I brushed the plaster twice daily for the first couple of weeks (as directed), then daily for a while and then fell into a pattern of doing it a couple of times a week. On about week four we noticed the plaster "getting lighter in color". We called the pool company and they said not to worry that it was just the plaster curing. Way, way, wrong!
Looking back now, with 20/20 hindsight, it is obvious that was the start of our scale problem. Now some 10 weeks further down the line the black plaster finish is almost white all over and this is why I post...
Two weeks ago I contacted my pool company and complained about the poor start up. After threatening to go through the BBB arbitration process if they did not acknowledge the issue they have agreed to work with me to resolve it.
4 days ago they started lowering the pH of the pool. Over the course of 2 days (using seven gallons of Muriatic Acid) the pH was lowered to <6.2. Almost all the other numbers are off the scale of my test strips too!
They have asked me to brush twice daily until the scale is gone. It's working but due to the scale of the problem I feel like I will be going until Christmas...2009!
Before posting these questions I have searched this (and other) forums as best I could. Please point me in the direction of other threads if I have missed something!
My ignorace of pool testing procedures obviously did not help the situation. So I need a decent test kit. I assume all here would recommend the TF100? Need I even look at anything else? Just checking!
I have a Pentair Mastertemp 400 gas heater that has not been bypassed while this low pH process is ongoing is there a danger of damaging it?
Is there a danger of damaging anything else?
How long can I safely continue to have the pool pH this low?
I read with interest the Ascorbic Acid article in the stickies. Will this help with scale?
Once I have finally sorted this problem I believe I need to use a sequestering agent, like Jack's Magic Purple stuff and keep my pool chemistry (particularly pH & alkalinity) in check. Is this correct?
If I use a sequestering agent do people recommend a test kit. It's expensive!
Sorry for all the questions, needed to get them off my back and out there.
Thanks all, in advance appreciation of your comments!
