Don’t Use Copper Sulfate!!
When organisms such as algae become a problem in private or commercia ponds, copper sulfate treatment provides an inexpensive solution. However, improper application of copper sulfate can create more problems than it solves.
Pond Problems
Excessive algae may accumulate in ponds. It may float on the surface and form a scum. Excessive algae can reduce the amount of oxygen in a pond to such an extent that fish die. Parasites such as ich may also harm pond fish.
CU Sulfate
Copper sulfate kills algae and many fish parasites on contact. It also will kill many weeds that infest a pond. Uniform spraying of a water solution of copper sulfate will guarantee that the copper sulfate spreads evenly across the pond. It is an inexpensive treatment and easy to apply.
Dangers of handling copper sulfate, Poisonous to Fish
Excessive application of copper sulfate will kill fish, especially if water is low in alkalinity. If a pond contains less that 50 milligrams of alkaline material per liter, a pond should not be treated with copper sulfate, according to the University of Kentucky College of Agriculture.
Other Precautions:
In a pond with algae, copper treatments can cause oxygen concentrations to drop, which may result in fish kills. Pond algae is a major source of oxygen production and by removing it this source of oxygen is also removed. In addition, oxygen will be consumed as the algae decomposes. If you are treating to kill algae, either treat in a series of smaller doses over time or have emergency aeration available.
Copper is also toxic to invertebrates, such as snails, and also most of the zooplankton in a pond (daphnia, rotifers, etc.), so if you are relying on the zooplankton as a food source (i.e. fry ponds), you may not want to use copper.
Last Note; Dangers of using copper sulfate.
In review, copper sulfate:
Has short term effectiveness and therefore is often misused and overused. Copper remains in the pond and does not bio-degrade.
Copper sulfate can be toxic to fish and other organisms.
Copper sulfate results in copper build up in pond sediments and creates a sterile bottom in the pond. Besides many important organisms, it kills beneficial bacteria.
Beneficial bacteria such as our all natural, Bio Lake Clear product, breaks down organic matter in the pond including silt, sludge, decaying plants, etc. into harmless chemicals. Beneficial bacteria and algae both feed on nutrients in the water available from the silt, sludge, decomposing plants, fertilizers, etc. By adding beneficial bacteria on a regular basis, you increase the beneficial bacteria colonies and therefore have more bacteria working for you to keep the pond clean, clear and healthy.
We recommend the use of our all-natural beneficial bacteria product, Bio Lake Clear and Ecosocks GC to treat ponds and lakes for algae control and faster organic matter decomposition from silt, sludge and decaying plants & fish.
How long after applying to lakeshore can you use beach for swimming? Trying to kill snails that are carrying the larvae of swimmers itch
I have 8 acres of water and lots of algae. Can you email me info about the Bio Lake Clear?
Thanks,
