i have 5 peacocks and a rtc in my tank....a pleco i had recently died and now the algae in the tank is starting to accumulate... i have some tablets for the water that clear the algae off the glass (which i have used with community fish and work great). i want to know if these are safe for my tank now. i would not be happy in the least bit if they had an adverse affect on my pb's and rtc.... opinions???
