TVC Total Vegetation Control would be a good product to use under the pool to prevent growth of most grasses for up to 1 year. Applying a fabric liner under can also help. If they are coming through the liner that could mean a hole was already there that allowed them to growth through depending on the weed, very few can grow through the liner itself without a hole/acess to sunlight. If the grass has already grown, pulling and patching is best.
