I was thinking about this earlier, as I bought another 4 gallons of bleack and realized my recycling bins are totally full.

Say a pool is a semi batch reactor, and you have some reactions

C(t) = Chlorine impulse

ra = - kb*A^n*C^m - Algae destruction by chlorine

ra = +ka*A^p - Algae growth

rc = -kc*C^o - Chlorine Degredation

So, If I'm trying to eliminate algae, I could say that

dA/dt = + ka*A^p -kb*A^n*C^m

dC/dt = C(t)-kc*C^o

Does anyone know if these are 0, 1st, or 2nd order reactions?

Either way, it would be interesting to see if your total chlorine usage (Integral of C(t) untill the pool is clear) is lower when you add all 25 gallons of bleach at one time, or if you add say 4 gallons per day during your shock treatment.
