    Major problem

    I recently noticed that my automatic fill was going on more than usual. I took a close look at the pool and found that the gunite / plaster has cracked. There are a couple of cracks that seem to join up. Total crack length approx, 20 feet. I wonder if I can get a smaller fiberglass pool and just set it in the existing pool and back fill around it.
    My pool is a 10,500 gallon (420 Sq Ft ) kidney shape. A hand made sheer decent waterfeature. STA-RITE HRPB30, Sand filter 30" 98 GPM,
    1 HP Maxi-Glas 2 pump, BBB Method, Taylor K-2005 test kit, 50 Watt 12V low-voltage pond light illuminates the pool at night for a nice soft glow.
    250 gallon stand-alone hot tub. Got it FREE!

    I'll bet it's cheaper to fix the crack and re-plaster.

    In order to drop a shell in, the old pool needs some level of demolition, bringing the costs up substantially.

    Where is the main crack? Can you post a picture?

    Probably far cheaper to repair. There is a fiberglass product that can be installed on top of the existing pool structure, but it's not cheap. I don't recall the name of the product, but it's not a DIY project. I don't have personal experience with them, but you can google "fiberglass pool coatings" for some possibilities.

    I have a guy coming tomorrow to give me an estimate. He said that he could epoxy the crack's. One concern he had was if the earth under the pool was eroded. If that was the case, they could inject something to fill the void. The pool is 1/2 empty now.

    Re: Major problem

    I'm in the process of acid washing the pool. http://smg.photobucket.com/albums/v6...2/ACID%20WASH/ What is the differance between the light blue and the off white coloring? What color should I have when completed? Thanks

    The light blue is copper sulfite staining, and the off white color is scale (you can also see it on your waterline tile). The plaster, depending on how old/stained you started with should get closer to white once you are done. That looks pretty old and stained though, so you may not get it as white as you would like. Be careful how much acid you use as well, as it will "eat" the softest material and leave your pool like sandpaper if you get too aggressive!

    Re: Major problem

    I was able to locate the source of the leak. It seems that a pipe for the infloor cleaning system has broken. Rather than break up the entire pool bottom to replace the broken pipes, I opted to plug the pop up heads. I have acid washed the pool and caulked the hair line cracks. The filling was completed yesterday and the pump is back in operation. So far - so good! I'll be doing a complete battery of water tests today and adjusting as needed. The acid wash really helped to clean up the pool surface. It was long overdue!

    Tests results:
    CL 2
    PH 7.6
    CH 230
    ALK 80
    CYA 0
    TEMP 59*

    I'm using some pucks to bring CYA to 30, then I'll switch over to 10% liquid chlorine.
