The main advantage of the DROP.2 or any algae scrubber is that if you size and operate it properly (based on
how much you feed), it can be the only filter for your tank, even replacing waterchanges. It can, however, also
be used with other filters. Some other filters such as carbon dosing (Zeo, pellets, etc) may slow down the
scrubber, but nothing will really "hurt" the scrubber except possibly large amounts of algaecide or copper
medications. The DROP.2 is also dry-out proof, since it's always under water.
Comes with 3 ft (90 cm) of vinyl airline, but requires a small air
pump. Any small pump will work. It is the air bubbles which move water into the growth
compartment and up the growth surfaces, and also supply carbon dioxide (CO2 in the air) to the surfaces,
which allow algae to grow in the filter
The LED is a single red (660 nm) 3-watt LED, which is sealed in polyurethane, and then sealed again in
epoxy. Some red light does come out of the bottom holes, and they make little red dots on the bottom of the
aquarium or sump. You will need to get a timer so you can
run the LEDs for up to 22 hours per day (not 24). The LED never needs replacing.
The DROP.2 will need to be cleaned ("harvested") every 7 to 21 days or when thick with growth. Just lift up
the DROP.2 out of the water, pop the lid off, and pull the algae out. You can even feed some of the algae to
your fish, and there will probably some some pods inside that you can feed too.

outside of the USA might require you to also pay an import charge when it arrives, although the DROP.2 is

least 3" (7.5 cm) of water to operate in.
"I have a couple DROP.2 from Santa Monica, and they work good!" -- D Maul on the R2R site.
"My DROP.2 works great, and was thinking about getting another one. I installed my second Drop 2
purchased in the recent group buy. The first scrubber was installed [about 3 months ago] and is doing a
great job. The biggest difference I seen was my phosphate level went from 0.11 to 0.03-0.06 range " --

"great product [DROP.2] and service" -- katzolicious on ebay
"I was thinking about getting another DROP.2; I like how it fits in the sump on the JBJ 28" -- Dan Budz,
"The algae still seems to be quite dark on the green grabber material but has grown a fluffy algae on the
inside of the lid..." -- Centralscot on the scrubber site.
"Works perfect! 10 mosquito fish and 2 marble crayfish in my 5.5 gallon breeder tank. Thank you for a great
product my tank parameters are excellent for a growing thriving tank. Here is a pic..." - Keith K.
"It's doing great" -- Mike Patterson
"Everything is working great. I like that the scrubber algae can be used as fodder for crayfish. Ive
been harvesting the algae and pressing and drying it into pellet form. It sinks like a rock. Also
getting double usage out of the fishes main food; is cost effective instead of just pouring your
nutrient filled tank water down the drain. Also with a check valve on the air pump the scrubber works
perfectly when your on vacation in Florida for 10 days; no pumps nothing to get hurt or sucked up or
overflow while still maintaining water quality." -- Keith Knurick
