Required fields are marked *. Thanks for enlightening me on what I thought I knew and, obviously, didn’t. Actually now that I look at it, that’s a typo…it should read “plants provide protection FOR fish”, simply because plants provide protective cover and concealment from predators, and to an extent if you have small fry, they’ll be more protected from other fish that might try to feed on them. Before adding fish to a pond, it should be cycled and any algae already present removed to slow down future growth. As the fish waste decomposes, it can produce a harmful gas that lowers the oxygen levels of the pond. Picking up algae from the top of the pond may take some time but it works just as well. On top of this, new ponds which are not cycled have no established beneficial bacteria populations to break down dead algae, leading to spikes in substances which damage the natural cycle and aid in algae growth. Some of these contain copper, which is toxic to algae, another will degrade the cell membrane, and another contains hydrogen peroxide, which when applied directly on the algae, will damage, and kill it. Algaecides, you see, won’t help to break any of this dead material down, and if they contain copper, they’ll likely slow or restrict any natural decomposition that might take place. (Cold Water & Plecos), Do Pond Fish Hibernate? My common answer to this question is no. Plants such as Hornwort and Water Lettuce, however, are especially good oxygenators, easy for beginners, and very hardy to the changing seasons – two very good choices to get started. This is less a problem in ponds without fish, as pond plants are much hardier when it comes to these kind of treatments. As algae die, they fall to the bottom of your pond and begin to decompose. Step 1 Use a long stick or net to remove as much green hair algae as you can from your pond mechanically. Products on the market like Algae Fix, Cutrine, EarthTec, and Algae Off are all chemical products that do actually kill algae. Keeping things well-oxygenating, circulated, and filtered is really the best way to prevent algae from overtaking things. 3 Barley as an Effective Ingredient in Controlling Algae. Problems arise when levels of algae become high enough to interfere with the ponds natural nitrogen cycle, causing spikes in ammonia, nitrates, and a high reduction in dissolved oxygen. The dyes are highly concentrated and work to shade the pond water, blocking the majority of UV light from penetrating and being used by the algae. This type of algae treatment is basically a method of strengthening your ponds natural eco-system and nitrogen cycle, creating a balance which prevents normal algae from becoming too abundant.

Barley straw is a more natural way of combating algae in your pond. Pond plants do an excellent job of out competing algae for Nitrates an Nutrients in the pond as well as providing shade.
