Harmful Algae Blooms

Toxic HABs are becoming a feature of a global water crisis

Harmful Algae Blooms (HABS)

Harmful Algae Blooms

The Problem

HABs are Harmful Algae Blooms formed by toxin producing cyanobacteria (also known as bluegreen algae). They are the destination that you reach when you have passed all the milestones along the way, sediment and muck accumulation, invasive weeds, algae blooms, fish kills and failed to deal with them effectively.

Cyanobacteria are incredibly hardy, adaptable resilient and versatile organisms that are very opportunistic in exploiting sick lake environments to dominate nutrient uptake and bloom.

Cyanobacteria can produce potent neuro- and hepato-toxins. The microcystin toxin can kill a pet dog that accidentally licks it off its fur after playing in the water within 15 to 20 minutes. That is why health authorities are so strict about shutting lakes down to the public if they suspect there is a HAB event.

What is even more concerning is that recent research indicates that keeping people out of the water may not be enough to protect them because the toxins can become airborne with winds of just 7 mph.

Once you’ve reached the end point of the journey and CyanoHABs have set in you face threats to your health, lakes being shut down, the recreation and tourism industries being devastated and property values plummeting,

If the lake is in a water system that flows into a drinking water reservoir there is a risk that the toxins can get into the water and the health authorities will issue a “do not drink from the tap” order.

As with all other symptoms of a sick lake, CyanoHABs are a result of distortions in the nutrient cycle and a domination of nutrient uptake from in-lake sediment stockpiles by nuisance organisms like weeds, algae and eventually cyanobacteria.

How To Make It Worse

Once we understand that the real problem is the recycling of nutrients; (decomposed sediment organics produce weeds and algae that then die off, fall to the bottom and decompose to form nutrients again), it becomes obvious that the best way to make things worse is to promote nutrient recycling.

There are a number of ways to do this

» Herbicides

Herbicides quickly kill weeds so that the dead weeds fall to the bottom to decompose and perpetuate the nutrient recycling.

» Algaecides

Algaecides quickly kill algae so that the dead algae fall to the bottom to decompose and perpetuate the nutrient recycling.

» Chemical Treatments

Such as alum that clear the water and precipitate phosphorus down into the sediment to perpetuate  nutrient recycling.

» Conventional Aeration

Conventional Aeration raises dissolved oxygen levels in the upper layers of the water column. Because phosphorus precipitates out of the water at higher dissolved oxygen levels acts in much the same way as chemical precipitants by recycling phosphorus back into the sediment.

The difference is that chemical precipitation tends to retain phosphorus in the sediment a little longer, whereas when conventional aeration fails to oxygenate the sediment phosphorus rapidly becomes dissolved in the water again.

How To Make It Better

Harmful Algae BloomsSIS.bio installs its proprietary RADOR aeration technology and supplies proprietary digestive enzymes and nutrients that have taken decades to perfect. It is a chemical free, economically and environmentally sustainable solution that restores the aquatic ecosystem back to its natural state.

SIS.bio‘s RADOR aeration technology changes the anaerobic aquatic environment back to aerobic by destratifying and reoxygenating the entire water body and even the sediment. That means CyanoHABs and dangerous pathogenic bacteria cannot survive in the new oxygen rich environment and the fish can go back to the bottom to feed.

The next step is to treat the lake with proprietary enzymes that digest the muck making the nutrients bioavailable to be used as proper nutrition up the food chain. This removes the sediment rich rooting bed that the invasive weeds take advantage of and they start to disappear too.

Now with fully oxygen-rich water all the way down to the bottom and no foul muck, indigenous aquatic plants can grow again and fish can spawn onto a clean sandy bottom.

Lastly their proprietary micro-nutrients foster proliferation of the tiny organisms at the bottom of the food chain like zooplankton so when the fish hatch they flourish and grow naturally as they get their fair share of the nutrients that were being hogged by the weeds, algae and CyanoHABs.

With more healthy oxygenated water to grow in and a new abundance of food supply the fish multiply and grow larger. The frogs, turtles and water fowl all benefit from the clean, fully oxygenated water for new food to exist on.

By helping Nature to counter the effects of our manmade disruptions, balance in nutrient processing is restored, and a healthy sustainable eco-system exists again. My Sick Lake is healthy again!
