Newbie w/ very GREEN pool - HELP!!!

[dmanb2b]

To speed things up you may want to consider a partial drain and fill to lower your CYA level. Battling algae with CYA at 90-100 will be very difficult. It can be done, but you are going to need a ton of bleach/liquid clorine to maintain that high of an FC

Should I keep my solar cover on to help keep the chlorine in? Or will the high levels of chlorine ruin my cover? And will my high levels of chlorine affect my cya test results?

[Watermom]

Leave the cover off. Fumes from shock levels of chlorine can damage the cover. Your cya test will not be affected by the high cl levels.

How soon should we expect results (green clearing up)? couple days? a week or more?

Thanks so much all your help. So glad I found this forum!

If you maintain the shock level as it seems you are, you should start to see improvement within a couple of days. Run the pump 24/7 and watch your filter pressure. When it rises 8-10psi over your clean filter pressure, backwash.

3 days now with my FC at 25 ppm or higher and no significant change. The green may have paled. CYA still at 100. A little more patience and persistence? or is water change a must? If I get a chance I'll post pics tomorrow. I haven't done a backwash yet. The pressure only went up about 5, but thinking maybe it would be good to go ahead and do a backwash. Have swept/broomed the pool everyday. Yesterday just left the "lil shark" work, maybe that's not as good? It has been raining off and on too. Is that setting me back?
