hi guys! I’m very new to this pool stuff and I’m trying to learn as much as I can. I just set up an easy summer Waves 16 ft pool. I got it balanced and shocked it with hth ultimate shock last night. I added 3” hth chlorinating tabs this morning to the chlorinator. I just read those are Trichlor....is it safe to use hth shock I mentioned since it’s calcium hypochlorite along who Trichlor tabs? All this stuff I’m reading online is making my head spin.
