first time expierence

can I use topfin biological cleaner for aquariums in my dwc?

for what reason?

generally if it's safe for fish, it's safe for plants

It is to keep the water clean and I hope any algae away. I tried about half of the recommended amount and hoping it doesn't harm. My thoughts are like yours if it is good for fish should be ok for plants I hope. I had read some use peroxide and I don't want to go that severe. What I did used didn't change PH much. Thanks for confirmation
