Hi, sorry for not have numbers for my water test from the pool store. They seem to be not wanting to get me a detailed report. I have been fighting the green pool for about a month now. My pool is inground about 30K gallons. I have checked my TC level and it is sitting stable about 3PPM and PH is 7.4 and stable. The CYA I think is above 100. Normally I use tablets / floater to maintain the chlorine levels. I have added in the past few weeks, many bags of shock, algaecide 60, 4 gallons of chlorine without any luck. I also clean my filter (starite 135) w/2HP motor every two or three days. Even put the tablets in the skimmer and a secondary floater in the spa pool (overflow's to the pool).
When I run the vacuum, the spa looks like a dark green pool since I have the filtered watter go into the spa first.
The filter is very green and I clean with hose adapter from Leslies Pool ever 2-3 days.
During the past weekend, I have done three back washes (about 3 inches) with vacuum to review the layer of green **** on the bottom of the pool and added one gallow of chlorine from Home Depot. Any problems with the stuff from Home Depot, the price is not bad $6 / 2 gallons.
The water is now finally getting clear green and starting to see the bottom in the middle and shallow parts. After one/two days there is enough bottom **** to do another vacuum or backwash.
Should I continue to drain about 3 inches at a time or do the final heavy shock of adding 6+ gallons of chlorine?
Again, sorry I don't have the water tested numbers from the pool store and typo spelling errors...
Getting a good work out but also spending too much time with the pool and wife want's me to spend more time with my two little boys... Need to teach them to swim soon...
