Welcome to algae scrubbers. We are the only source for patented upflow scrubbers: U.S. Patent 9,115,008 and 9,708,207. All the oceans, reefs, lakes and rivers are naturally filtered only by algae, and all the organic particles remain in the water to feed the creatures. Reduce your glass cleaning and water changes, and create an environment for living micro-animals to grow inside the scrubber. No more dosing or possible overdosing. No more refilling. No more pale corals from low nutrients, and no more sick animals from high nutrients. Far more powerful than chaeto or refugiums, and does not remove the food particles. And you can use the algae as food!
 
Get the no-overflow advantage of an upflow scrubber: since it is ALL underwater, it can't overflow onto your floor.
 
Finally an aquarium filter that offers drop-in installation in the smallest of spaces, along with reduction or elimination of water changes and nuisance algae. And it's small enough to drop into the back compartment of most all-in-one aquariums. It operates the way the oceans and lakes do, using algae to do all the filtering, and it truly can replace all other filters in your aquarium if sized and operated correctly. The DROP1.2x grows well in water with phosphate up to 0.5 ppm.
 
Strong injection-molded case! This DROP1.2x drop-in algae scrubber has 28 square inches (170 square cm) of extremely rough Green Grabber ® one-sided algal growth surface which can grow up to 1/2" (1 cm) thick green hair algae. This is designed to absorb the nutrients from this much feeding per day: 
 
1.2 Frozen cubes, or
12 Pinches of flake, or
12 Square inches (72 square cm) of nori, or
0.12 dry ounce (3.6 grams) of pellets
 
The physical size or number of gallons or liters of water in your tank or sump does not matter; however the amount of problem rock you might have, does. If you have rocks which are soaked with phosphate from having been in a problem aquarium, each 10 pounds (4.5 kg) of this problem rock will add 0.2 cube a day to your feeding amounts; so be sure to account for this when choosing a scrubber size or number of scrubbers. For example if you feed 0.5 cube a day, but have 20 pounds of rock that came from a tank with nuisance algae problems, this rock will add 0.4 cubes a day to your feeding. This applies even if the rock was dried out and bleached, because this does not remove any nutrients from the rock.
 
If you feed more than the above amounts, you can get multiple DROP1.2x units; multiple units are preferred over one larger unit because you can clean one unit per week, and because you'll always have one unit filtering while the other one starts growing again after a cleaning. Multiple DROP1.2x units are also good for backup.
 
The DROP1.2x will fit into any size aquarium, sump, and almost all back compartments of all-in-one aquariums. Nano and pico tanks, with sumps on the back side, normally have compartments at least 3" (15 cm) wide; and the DROP1.2x only need 3.5" width.. And of course it can fit into the display (the main part of the tank). The DROP1.2x  has a special plate under it which allows it to sit on the bottom of your aquarium or sump, including sitting on sand; the plate not only keeps sand from getting into the filter, but also blocks most of the red light from coming out.
