Copper Sulfate


I have a 200 gallon tank with 7 really nice African cichlids.

I am new to aquariums besides this tank, and i'm really enjoying fish keeping!

When i was at the pet store one of the people told me that copper sulfate is good for cichlids digestion. she said that only put a small amount in because they don't like too much. I think she said to put it in every water change. She didn't really give details, just said ad about a half a tea spoon at water changes.

I was wondering how many of you guys do this and where i can get it?

Thanks guys!

Welcome to the forums and TFK first of all

I suspect the reason the person at the fish store suggested you put Copper Sulfate in the tank at each water change is as an ICH prevention. Copper Sulfate is used in a lot of ich medications.

Long term though it will kill almost any plants you have in the tank and is also bad for fish.

It will also treat internal parasites and this is perhaps what they also suggested using it for.

Long term though I seriously would not use it or any other form of treatment until it is absolutely necessary, I have been keeping cichlids for 14 years and have never once heard of copper sulfate being used to aid digestion until you posted it here.

Copper Sulfate long term is extremely toxic to ALL aquatic life. It is fine using it for ich medication but NOTHING else.

10g Fry / Hospital / QT tank (as needed)

75g Saltwater Reef, Ocellaris Clownfish, Lyretail Antias (baby), Lemon damsel, Longtail Fairy Wrasse, purple dottyback, snails, crabs and a few LPS corals.

220g Still sitting empty (come on Lottery I need the numbers to come up!)
