Frosty,
Where do you live? The reason I ask is that I can possibly shed some light on Anthony and Sylvan as far as the Houston area is concerned. I had an I/G plaster pool completed in Jan. 2009. My pool designer was very good and prompt with my questions, concerns, etc. He at times went beyond what I would have expected and was very happy with our communications. After a few hurdles with utility relocation, my build went fairly well. The problems arose within the first two months after the pool was completed, mainly with my pool plaster. The first issue was discovered by the "Pool School" guy who noticed blue swirls in the plaster. This was corrected by draining my pool, tearing out the plaster, and re-plastering the pool. Two months later, I noticed light brown to gray stains forming at various locations at the bottom of my pool. After visits by the warranty department and the plaster company, it was determined that my stains were "hydration" and that they would decide on a solution for them at the end of the summer. I then joined this excellent forum and gained the knowledge neccessary to care for my pool, almost none of which was provided via the pool school guy or the pool company. After 2-3 more months of watching the stains increase, the pool company drained my pool for a second time and performed an acid wash. This got rid of the stains and I was happy again, but not for long. As of two weeks ago I noticed the stains are returning in the same places. I have contacted the warranty department and they are aware of the issue. Im curious what they are to do this time to correct the problem. I would imagine a third pool drain and a second plaster job. What sucks is that I expressed my interest in having the plaster removed previously and a pebble tech product installed at a reduced price given the problems I was having. Unfortunately, I was quoted $5,300 :grrrr:

So needless to say, I still have plaster.
Currently Im waiting on having my Color Logic Led Light replaced due to the stainless steel ring tarnishing due to the plaster company laying the light face down at the bottom of the pool during the acid rinse. The light was dropped off 4 weeks ago and has been sitting on my pool deck waiting for the electricians to replace it :grrrr:

. I was told they would be at my house last week tuesday or wednesday but they never showed. Also, if you are given an Ozonator, you will be provided with an inline chlorine feeder to aid in the sanitation of your pool. The only problem was that my flow valve for the feeder produced build up and prevented me from adjusting the amount of chlorine being added to the pool. The warranty dept. is mailing me the part which is easily replaced.
I have a spa as well which has a spill over feature that goes into the pool. Only draw back is my PH is always on the high side until I knock it down with muratic acid. Also, with my current equipment set up, my FC was never maintained above 2 PPM. if I hadnt joined this forum and learned the ins and outs of FC, I would not have known to add liquid chlorine to keep my FC at suitable levels. I myself have read all the posts about Ozonators etc and Im still on the fence about thier reliability. I will admit that I have not had any problems with my pool as far as algea blooms etc. So, Im confident that the equipment set up is decent, but not completely adequate for proper FC for the Houston heat and rain.
I have posted in previous posts, pics of my pool during the good times and the "stain" times but I dont know how to link them to this post. Hopefully one of the moderators can help with this endevour so that you can see what I have previously mentioned. I hope this helps. If you have any further inquires feel free to PM me, I can offer plenty advice as to the equipment A&S was installing and what they are going to now.
Keep in mind, my situation may be an oddity as far as the problems experienced, however, I know of two other pools that were built by A&S who used the same plaster company and are having the same plaster issues, then again, Ive only owned my pool for 8 months.
Hope this helps.
