Fritz AquaticsMardel Copper Safe Treats, 1-Gallon

Fritz Coppersafe is easy to use. 1 dose/wk is all that’s needed to treat Ich. Saves numerous water changes & is cost effective also. Harms the snail population so remove them prior to treatment. I’ve only had (1) sub-species of Thorichthys Aureum that didn’t handle the medication well out of all my fish from Geophagus to tetras, rainbows, Plecos, cichlids, & etc. 5/5 stars.

I haven't seen any results using this product as of yet. It's still early in the process.

Copper Safe or whatever various companies may call it, is really (Copper Sulphate). I have been using it for many years and it is the ONLY and BEST way to get rid of parasites, ick, and fin rot.

I've tried several different chemical options to treat my ornamental fountain in my backyard, and nothing worked until I used this stuff. Because my fountain is in the full sun, most traditional chemical treatments are ineffective and the algae blooms even when I dose at 2-3x the recommended treatment levels for my application. I had previously tried Tetra Pond Fountain Blocks, EasyCare Fountec Algaecide and Clarifier (worked somewhat in the spring but not the summer) and three of the AquaScape autodosing system treatments (Prevent, Control, Maintain). Not one of them worked, and I would typically have to drain and powerwash my fountain after 3-4 weeks to get a clean, clear fountain again. This stuff is AMAZING! There aren't doing instructions on the label for small areas like my fountain (this amount of chemical is enough to kill all the algae in a 10 acre pond), but you can find it on the internet. For my 500 gallon fountain, I put in 1.5 tsp every other week. I have had ZERO algae growth! This container will last me for many years, so it's not only incredibly effective, it's also really cheap. Everything I've read online would indicate it is safe for animals drinking the water, but it's not safe for fish.

Copper safe is the best I have found to eliminate unwanted parasites in my aquariums. With it being hard to find anymore I did not hesitate to purchase a couple of bottles. When used properly it provides excellent results.

Works great at killing marine parasites!

If you overdose just a little, fish die.

Won’t save you from some trouble found new better stuff as this is so costly noe

Excellent
