Hello, I have an old pool that we have just acquired that has obviously been neglected... I finally have balanced the chemicals but the marsite or plaster is just coming off... we have craters that had black spots imbedded and have scrubbed clean a number of times and I just added black out.... After all the reading, I think I just wasted $30 and need help keeping these spots returning.
