First BBB opening

[elesar]

Inground 16 x 32. Switched to BBB halfway through last season. Poured a gallon or so during the winter, and 1 stale gallon after removing cover.
Opening for first time under BBB method.
What is the suggested process? Do I use algaecides, metal removers, etc?
Water is faint greenish.
PH -7.3
Chlor 2.0
FChlor 2.0
Alk 110
Temp 70 F.
Thanks for help.

Check your CYA level and adjust to the 40 to 50 range if needed. Meanwhile, raise your FC level to the high end of the normal range. That should take care of the faint green if you do it soon. You shouldn't need any algaecide. Don't use metal remover unless you have needed it in the past. If the water looks reasonable, it will probably clear quickly. Keep an eye on it, as you might need to shock if the FC level starts falling rapidly or the water gets worse instead of better.
