If your FC is holding overnight and you have no CC then ignore my suggestion about backwashing early - no need at all.
The dichlor adds both FC and CYA, If you're willing to manually dose the dichlor for a few days to keep your FC in range(SWCG off), you'll save a little of your cell life, get closer to your CYA goal and use up your supply of dichlor.
- or - if manually adding the dichlor sounds like a pain, turn on the SWCG, put some stabilizer in a sock(start with half of what you think you'll need) and hang it in front of a return.
Either way test FC an pH daily add Borax if pH drops. Keep FC above the minimum on Ben's Best Guess Chart. Remember: As you approach your CYA goal, your minimum FC will go from 3 to 5.
Give it a week before you test your CYA - no need to waste the reagent. The granular stabillizer disolves very slowly and you'll only be adding a portion of your CYA goal with each dose if you choose dichlor.
I wouldn't worry about the TA, 80 seems pretty good, lower TA helps reduce pH rise cause by SWCG use. If you find your pH too unstable, look around these forums for establishing a Borate buffer.
Let us know what you decide and how it's going.
