What is red tide?
What red tide looks like close up.
What the colors of red tide?
It creates toxins that affect aquatic life's central
nervous system and they die. They also bother human's
respiratory system, especially those with asthma and emphysema.
What the colors of red tide?
Red brown, rusty orange, and shades of green.
Is red tide new to Florida? And, why it is so frequent in the Gulf?
No, it's been around since the 1700s. According to the FWC, "K. brevis thrives in high-salinity (salt content) areas [of Florida] but can tolerate a wide range of salinities and temperatures. The species forms nearly monospecific (single species) blooms by outcompeting or excluding other phytoplankton species.

Lorem ipsum
What causes a Florida red tide?

The following research is from Mote Marine Laboratory:
"The Florida red tide alga, Karenia brevis, needs the following components to form a bloom. The first is biology — the organism must be present in the water and it must out-compete other phytoplankton. The second is the correct chemistry — this includes the appropriate temperature, salinity, and nutrients that it needs to grow and multiply. The third component is the right physical conditions to concentrate and transport K. brevis. The fourth component is ecology – the presence or absence of other life forms, such as other marine algae that may encourage or inhibit K. brevis blooms" (Mote FAQs)

Ways you can help locally with red tide
Use less water to reduce the nutrients
in storm runoff. This way you don't "feed"
red tide that is already near the shore.
Use zero to low
amounts of fertilizer because
combines with the runoff water, and
it can "fuel" already existing red tide
that is already close to the shore.
Dispose garbage properly so
it doesn't fall on the ground and
end up in our waterways, which leads
to the Gulf.
Use native plants in Florida
that require less chemicals/fertilizers.
Donate to charities.
Volunteer with places like
Tampa Bay Watch or
Keep Pinellas Beautiful.
Help with local beach clean ups.
Contact your local representative and
write/email them
(House Bill 1135/Senate Bill 1552).
