Fine black substance on pool floor
I have a cartridge filter on 27 foot round pool. Water is clear and balanced. Every AM ther are black clumps all over bottom. I vacuum and 24 hours later they are back. Tried floc, cleaned cartridge, super shocked and used black algae treatment. Still have problem.The particlec are very fine, if you agitate the water on the bottom, it dissipates. Help!
