couldn't find pondzyme--are these safe to use?

Hey guys, the pictures show fish in the water so I'm assuming these are safe to use, just wanted to post pics and make sure since I haven't heard of anyone using these in particular.



Thanks a bunch

hey there mr ganja- i noticed that product controls algae w/ high levels of copper. i seem to remember reading somewhere that cooper can be toxic for mj plants. i've been using pondzyme this grow in 5 gallon dwc buckets and my roots are crest clean. i'll have to check to see if they list cooper as a ingredient

Hey, thanks for the reply. I also noticed the copper in the ingredients; I know copper alone is not bad for the plant (and is one of the micro nutrients if I'm not mistaken) but I'm not sure how high the levels are, or at what point the levels become toxic.

The other one, the "sludge reducer" doesn't have a list of ingredients, but here's what the back of the box says:



I think this is the product that I was really needing (not to mention the cheaper of the 2-- only $4 and it treats 1000 gallons).

I would not recommend using those. Pondzyme is readily available on line if not locally. I get mine at a landscape center that has a pond section.

going to loook for it at some Stores in my area today!
