how often do you add bleach?

This is the best thread I've seen on here in regards to how much chlorine usage is "normal". Seems to be about 2-3 ppm per day.

You need to get a test kit that uses the FAS-DPD method to determine your Chlorine level accurately including high levels. Ben's Kit is what you need but if you can't wait here's a link: http://www.taylortechnologies.com/ They will send it out same day so you could have the kit as fast as the delivery can get it to Hawaii. There are several kits -- The K-1515-A only does FAS-DPD.

You need to add Chlorine as often as your test dictates. To get rid of your algae your Cl needs to go to shock level (25 ppm) and keep it there even if you have to add 5 times a day. Of course you need to brush vacuum and brush some more. After holding the CL up there you can let the level drop to between 8 & 15 ppm. DO NOT let it go below the 8 ppm.

I can't stress the importance of an accurate method to determine your chlorine level. Your safety and sanity depends on keeping the CL level where it belongs.
