Hello from a new poster and thanks for all the wonderful posts and topics in here!
I may be in over my head but I've been reading through numerous posts to get back on track. I'll start by saying I may have used a few unnecessary chemicals that the pool store chain up the road has recommended...and my pool has been green since last October. After numerous shocks ($300 worth?) I started thinking it was the filter and 5 days ago ran ZeoSand Cleaner through per the instructions (the ZeoSand is 1 1/2 years old). Then on Monday it was recommended that I use Leslie's Super Floc. So Monday night it went in, ran the pump for 2 hours, turned it completely off as the instructions say for 12-48 hours...and here I am with pump still off.
Also of note, when Leslie's tested the water Monday my CYA was 100, pH 7.4, TA 100, FC 0. I currently only have a basic OTO(?) test kit but ordered the Taylor K-2006 on Monday. The CYA is too high because I've been using dichlor and trichlor.
So my new plan (and where I could use some confirmation) is to start vacuuming to waste today. This will continue getting leaves off the bottom and also to lower CYA. Then in a couple days when the new test kit arrives I'm planning to follow JasonLion's "Turning Your Green Swamp Back into a Sparkling Oasis." I have twelve pounds of cal-hypo 73% as of right now (and plenty of dichlor/trichlor which is apparently useless to me). For the rest of what I need I'm planning to try out bleach for the first time.
Any other thoughts or questions that I may be forgetting (or just completely clueless on)?
