Help....Can not seem to get the swing of this....

I agree with those saying your GFO is your issue. Honestly looking at your tank 125ml of Alk seems like a lot given the really light coral stocking.

That's how I felt but I test my alk weekly now and was test every few days as close to the same time as I could. I use a Hanna checker and I am going to pick up a Trident today.
