Feed fish sparingly
Algae thrives on ammonia, nitrate,
and phosphate generated from
uneaten food and fish waste.
Feed your fish only as much
food as they can consume in a
minute or two, 2-3 times daily.
Shorten and regulate
your light cycle
A lengthy light cycle encourages
algae growth. Use a light timer to
replicate a consistent day/night
schedule. Keep lights on 10-14 hours
per day for planted aquariums,
6-10 for ornamental setups.
partial water changes
Ideally, change 10% of your aquarium
water weekly to dilute and remove
algae-fertilizing excess nutrients.
Lee's Ultimate Gravel Vac®
offers an ideal solution that also
removes sludge and decomposing
organics from aquarium substrate.
Test your tap water
before water changes
Your tap water may contain
algae-encouraging elements –
especially phosphate. Eliminate or
significantly reduce these elements
with a Reverse Osmosis unit or
a Tap Water Filter.
Maintain your filter media
Bolster your filtration system with
phosphate-controlling media such as
our PhosPure® Filter Media
which removes phosphate and heavy
metals. Also, change your mechanical
and chemical media at least once a
month to ensure consistent results.
Remove as much
algae as you can
Scrape algae off your aquarium
walls with a Mag-Float, or the Eheim
PowerCleaner Glass Scraper.
Add a UV sterilizer
to your setup
UV Sterilizers use ultraviolet
light to clarify aquarium water and
eradicate free-floating algae (known
as green water) from your aquarium.
Add beneficial plants,
invertebrates, and fish
Plants compete directly with algae for
light and nutrients, and most often
succeed if given proper conditions.
In freshwater setups, Dwarf Plecos
happily consume algae from aquarium
surfaces, while Cory Cats eat excess
food from aquarium substrate before
it can fuel algae growth. In saltwater
setups, a refugium with macroalgae
can compete with nuisance algae. Find

and fish on LiveAquaria®.com.
