CrystalClearOneFix 32 fl. oz

How does it differ from Crystal Clear Sparkle ?

Would this replace the pond zyme, alerg destroyer and pond clear that I use now?

I don't see any application schedule. How often and how much would one use for almost a 4,000 gallon pond?

Am I reading this right to say that it's $22.95 for 6 bottles or $22.95 each times 6 bottles?
