Green algae water is usually a result of no pool circulation, abandoning the pool, or lack of sanitizers such as chlorine, algaecide or chemical imbalance in general. If you have decided to replace your liner at this point, it is still important to keep your chemicals balanced because if you have a hole in your liner, the green water could contaminate your pool hard bottom. If you want to use your existing liner and clear up the water, I would take a picture of the pool, along with a water sample and take both to your local pool dealer and have the water tested.

Pool coping/edging that is seperating from your concrete pool deck is a problem that should not be ignored. Crumbling concrete and seperating coping only get worse with our Winnipeg, Manitoba winters. The frost makes these matters worse and is unforgiving. These problem areas can usually be filled with a sealant like silicone or larger gaps can be grouted in with grout concrete. Replacing your coping is usually not an option when it is poured into the concrete and also attached to the top of your steel pool panel. Read more about Crumbling concrete and gaps by coping
Your pool floor is usually made up of a blended sand and cement mixture which is troweled smooth. The appearance should be a light sand to white colour and it should be hard. Here is a picture of a pool floor which is 20 years old and is in great condition like it should be. Pool leaks coupled with a liner that floats from ground water usually result in a soft pool bottomt that will have to be redone with a skim coat of sand and cement. As you may note in this picture there is some surface rust at the bottom of the steel panels. This can be sanded off and is only minor. Read more about Whats Under Your Pool Liner
Leaky salt water pools seem unforgiving. Seems like it does not take much leaking water and the damages are apparent. Once the salt is in the ground it keeps on rusting the steel pool panels. The galvanize coating gets eaten away and the rust comes through. Sometimes it only takes several months before damages similar to this occur. Best advice is to have pool leaks looked after promptly instead of leaving until next year to fix, especially if you have a salt water pool. Read more about Salt water pool damage
