Sharing experience on recent used of above in case anyone thinking of using. Tank having slime algae for weeks and got tired of manual cleaning. Read up and found either above or API product as possible solutions. Tried Easy Life according to instructions but with an extra day of dosage (Kia Su syndrome!!). After almost 3 weeks of first dosing, I have not seen any new outbreak yet. 1-2 casualty on livestock during treatment but not sure if it's due to this or just coincidence. Think likely the latter as other livestock remained healthy and eating well. Seems to be effective but will monitor further.
