Toxic Algae vs. Harmless Algae

July 29, 2013

Algae can appear in different forms and different colors.  Is your algae safe, or is it toxic?  There is no way to just look at an algae bloom and tell if it is toxic. 

Green Algae can be picked up when a stick test is done.  If you poke a stick into the algae and the algae grabs on to the stick, is stringy and has a texture, this will tell you that it is a filamentous algae and it is safe.  It is the Blue Green algae that can be harmful.  There have been pet and livestock deaths due to the amount of consumption.

Cyanobacteria, also known as blue-green algae, looks like someone took a can of green paint and dumped it into a body of water.  This bacteria can also be reddish-purple or even brown in color and is also known in the marine environment as “red tides”.   Harmful algal blooms can decrease the water quality, produce an awful odor or taste, and cause the production of algal toxins.  When a stick test is done, the algae will not grab on to the stick.  There is no consistency to blue-green algae and it will make the tip of the stick wet.  Not all cyanobacteria algae is toxic.  And even if your algae tests non-toxic one day, the next day it can turn toxic.

As algae dies, it produces toxins and some of those toxins may be harmful to humans and wild life if the water is ingested or comes into contact with the skin.  As the summer temperatures rise, you can experience a new algae bloom every 10-14 days.  With every algal bloom, it is very important to use a copper-based algaecide to keep the algae and scum levels under control.  Our liquid, concentrated algaecide, Mizzen™, may be used in fresh water lakes, ponds, potable water reservoirs, water gardens, irrigation ditches and many other bodies of water.  Mizzen will help control nearly all types of planktonic and filamentous algae and chara.

In addition to an algaecide, the use of phosphorus reducer is very important to improve water clarity and help prevent or reduce nuisance algae blooms.  Storm water, animal waste and fertilizer are just a few ways that phosphorus can get into your body of water.  Our PhosControl® makes an invisible layer on the bottom of the pond and bonds with the phosphorus making it unavailable to aquatic plants and algae.  Each pound of phosphorus can produce 500 pounds of aquatic plant and algae growth. 

Making sure that your water’s nutrients levels are under control will help in deterring future weed and algae growth.  With the warmer weather that we have been experiencing, the water temperatures are heating up and if you mix that with high levels of phosphorus, chances are  you will have an algae bloom.


Algal Blooms in Lakes and How to Control Them

July 25, 2013


During the dog-days of summer, conditions are just right to cause blue-green algae to grow very quickly, resulting in algal blooms in lakes.  These blooms can create a noxious smell, discolored water and can even sometimes kill fish, which die when unable to get enough oxygen from the algae-dominated water.  Combine this in some cases with an abundance of phosphorus from agricultural runoff, sewage treatment plants, lawn fertilizer, water treatment plants, and septic systems, and more algal blooms can occur in lakes and ponds.

Pond and Lake Weed Rake Product Line Expanded by Lake Restoration

July 18, 2013

We are expanding our line of pond and lake weed rakes to include new rake tools, rake and weed control kit bundles, and new options for our patented LAKEMAID® lake weed removal machine.  New to the lake and pond weed rake product line this year are several hand held rakes:

Aquatic Weed Eradicator 

The Midwest Rake Aquatic Weed Eradicator is a lake and pond bottom weed removal tool. It has 28 inch blades that is adept at getting weeds out at the root.  

Screening rake

The Screening Rake is ideal for sifting, grading and screening stones and debris from sand or soil. Ideal for beaches.

Weed Razer Pro

The Weed Razer Pro is a lightweight, hand operated weed cutter excellent for cutting every type of pond and lake weed.  It is adjustable from 12 to 62 inches. 

In addition to adding these rakes as stand alone items available for purchase online, we are now offering a bundle with each rake along with either the MuckMaid or the RestoreAccess Ultra G kit.  These kits are designed specifically for beaches and swimming areas and provide a more comprehensive solution to help eliminate silt and muck in addition to the weeds themselves.


The LAKEMAID® weed control removal machine, meanwhile, is now available with 24 foot arms, allowing for much greater coverage and faster results. The LAKEMAID® sits on top of the water and removes pond and lake weeds, silt, and muck near docks and in swimming areas by dragging weed-removing rakes across the lake bottom.  Compared to other mechanical tools, it is lightweight, easy to install, surprisingly portable and shareable, and priced competitively.

“We feel these new rakes, the bundles, and the added options for the LAKEMAID cover almost every weed control need out there,” says Mary Jo Furman, Sales Manager for Lake Restoration. “Ultimately it’s about enjoying the pond or lake and getting to the beach, and these products make that possible.
