Hypo? How much to put down? Does it dry too fast in the sun?
« on: July 23, 2018, 09:02:36 am »
About to use Hypo for the first time. I wondered about it drying to fast in the sun? Do you apply it once or twice to stop it drying? Do some people mix it with anything in particular ratios?
Thanks,

Mixing ratio depends on the severity of the algae and moss you are treating

Ideally your looking for 3% so the mix also depends on your hypo start strength

Yes it will dry quickly we normally apply then lightly  rinse over with in 10 minutes  then check again if the hypo has done it’s work five minutes after this

We mix 12% strength at 4-1 with water.

It is drying out quicker in this hot weather, I sometimes lightly mist it with the lance so as not to wash  it off but keep It damp

Is that four parts water? I guessing it is. I used 15% the other day and yesterday 11%.  I didn’t think it would be that different but that 4% I think makes lots of difference?
