Ask just about any old time pond owner what he or she uses to control pond algae and solution will likely be «some copper stuff». It’s not uncommon identify that algaecides of every type have been used for many years to treat ponds which have turned green and slimey.
The frequent kinds will most likely have kind copper sulphate on the label therefore often are in liquid or powder make up. They have the advantage of working quickly to kill the algae and can work on surface and submerged algae types.
For the most part they are relatively safe for desired plants and nevertheless touted being safe for fish as well. Due to this safety level and the speed at they will can work, they to be able to a favored approach to pond algae control.
But unusual remains, «are they the particular best option when seeking at pond algae control?»
While makers of such products will say yes, and reaffirm that their safety when applied per directions, others are yet to found this to be the case.
As a pond care advisor I’ve had many pond owners contact me with the dilemma of dead or dying fish after applying an algaecide product. In fact it doesn’t really matter what brand or what type. The reality is that if the product is in order to kill algae quickly, and is also applied in the certain situation, it will likely result in the fish destroy.
The is actually not a great deal of in crucial appetite itself but in the fact that if a pond is heavily infested with algae and via a tunnel it is killed off quickly, theres a high probability that the die-off will pull very much the oxygen out of the pond very quickly. When this happens, unless it owner has steps to increase aeration, then the fish is likely to suffer and also will die.
To avoid this, it’s better to treat smaller sections or segments for this pond algae bloom, rather that treat the entire pond instantly. In this way, you can control just how many oxygen depletion and algae die-off associated with the treatment. Do a bit simultaneously and you shouldn’t have an issue with fish kills.
Unfortunately problems with fish is not the only disadvantage in algaecides. A much more insidious and problematic issue can arise with their repeated include.
Think from it this way. Anyone who know’s anything about pond algae is aware that algae prospers in ponds where organic sedimentation is heavy. This organic «debris» is comprised of decomposing vegetation like leaves, grass clippings, tree branches, or whatever else may fall in the pond at any particular time.
Now otherwise this could happen. When algae is killed by an algaecide and it dies quickly, in instances it isn’t removed of this pond. It simply sinks for the bottom and begins to rot. Since it is does, just like the leaves and grass clippings, it will begin improve the nutrient load in the water, exactly like compost might do in the backyard small garden. This situation in a pond leads to more or increased algae growth.
So, this particular in mind, the temporarily benefit of using an algaecide for a final clean of the pond is just that, a short-lived solution that will ultimately create the situation where more algae will be promoted, and since this algae will want be treated, an endless cycle ensues that requires regular remedy.
This application and cycle also inside an accelerated filling by the pond due to sedimentation, which down the road, might require dredging or a full cleaning if the pond is a short backyard water garden.
In the end, many believe that although algaecides have some benefit, they ought to not function as a first approach treatment on pond algae problems. Ideally it’s best to look at other solutions that are less toxic, dangerous, and effective at cleaning the pond up of not only algae issues but among the organic fortify as sufficiently.
