In case anyone is reading and this may be helpful to your situation- After about 10 hrs of the dichlor shock, water was still yellow. Right before going to sleep- we added a calcium booster, as we knew it was low. I hated to pour it in, figuring we were going to drain tub in morning due to yellow color. This morning the water has no yellow! Other than a slightly high ph- things look good per strips. I’m off to the pool store for another test to confirm. I want to order the Taylor test kit- but I’m not sure if we are going to keep using Dichlor method or switch to Bromine.

Hi - newbie here. We have a brand new hot tub, 290 gal LifeSmart tub. After hook up and initial fill using a hose end filter due to well- water was clear looking and all seemed good. We added Spa Metal Free by Natural Chemistry, put filter in and turned jets and heat on. Within 5-10 mins the water was a light green and then turned mostly yellow with 15-20 mins. We did a Spa Purge (foaming and a bit reddish brown flakes appeared), filter also orange/red color. We then drained tub and rinsed filter. Next day, we filled tub again using a hose end filter. Again, water was clear. Added Spa Metal Free and began circulating and heating the tub. Again within 5 mins water in tub turned greenish to yellow. My question is, could the Spa Free Metal be causing discoloration? The plumbing in new tub contaminated? Or is our water (3 ppm iron well water) clear and then turns yellow upon heating/aerating? Anyone have any ideas. My plan now is to shock to see if the yellow goes away. Ph is about 7.4 and Alk is 115-120 per pool store. On test strips, alk looks lower.

New hot tub owner. Filling from well water with a hose end filter. Added spa free metal product while filling tub. Approx 2 hrs after tub was full, we turned on jets and heat. Within a couple minutes the water turn a light green/yellow color. 2 hr time between fill and turning on jets/heat the water was clear. Water has stayed with slight green/yellow tint for two days. Any ideas on the color change immediate after turning on jets/heat with only the metal free product in water?
