We just installed a new pool and had a defective pump part which took 2 weeks to get a replacement. We watched our new clear water turn swamp green. We have a SWG. We, of course, wanted to avoid chemicals and are unclear how to proceed. My understanding is that we follow the above instructions for regular pool setups and my question is, do we need anything special to get our levels correct? We haven't tested anything yet but we are not sure if we need specific stabilizer or shock for SWG.
