If you are using self-found grapevine wood rather than purchasing it you have to factor in the risk of pesticides having been sprayed on the grapevine wood during the farming process and we would not recommend that you use self-found grapevine wood or veins in your tank.

This is why we always recommend that you use aquarium safe grapevine wood in an attempt to prevent there from being any risk of the grapevine wood having any pesticides or chemicals on it that may harm your fish.

The majority of self-found grapevine wood is from either the wine or fruit industry where a wide range of pesticides are commonly used on the wood to treat it prior to use.

As you can probably imagine, these pesticides and chemicals on this wood can present a threat to the fish and other organisms in your aquarium such as snails and shrimp.

Although some people do take the time to wash these chemicals off their grapevine food, it is actually more difficult than most people initially realize to make an object covered in pesticides aquarium safe, especially for tanks with sensitive fish, corals or anemones in it.

What Is The White Stuff Growing On My Grapevine Wood In My Aquarium?

Even properly cleaned grapevine wood has a high chance of white fungi growing on it when it is kept submerged for extended periods of time in an aquarium and this is totally normal.

Many fish keepers using grapevine wood in their aquariums ask if this fungi can harm their fish but it is considered fish safe although unsightly so most people clean it off their grapevine wood every week or two.

Due to this increased workload for keeping your tank clean, some fish keepers will switch over to a regular driftwood that does not have this fungi problem to help keep their tank maintenance time as low as possible.

This is very common as constantly having to clean the fungi off the grapevine wood does end up being a pain.

Still, the unique look of grapevine wood and its low prices does keep it as a very popular option for many fish keepers, especially those who enjoy the tank maintenance process of cleaning and caring for their tank as much as viewing their fish.
