“Now we are further into the season I can report that the viresco Koi performance in eliminating blanket weed improves with time! Even though I have done partial water changes with occasional filter cleaning and occasional pond hoovering these activities have made no difference to the virescos sustained performance; as there is very little blanket weed present, (at all temperatures) and the situation has improved even more since I last communicated with you.This is amazing stuff! Especially as I only used half (for 1500 gallons) of the 3000 gallons dosage I bought from you. I therfore highly recommend anyone with blanket weed problems to use it as it certainly does'nt dissapoint! and in my opinion its worth every penny.”
