works great.
Larger size is more effective
Much better in the larger container
I always buy the 3kg tubs of this chemical. Best prices I can find. Comes quickly as well and free shipping over $150 which is nice too!
Delivered very promptly and I did not have to drive across the city to replenish my supply.
