Remove nuisance algae, nitrate and phosphate. Ultivate seaweed for feeding. 6x installed on dirty freshwater tank. 6x first cleaning on dirty freshwater tank. Similar DROP1.4 installed on saltwater reef pond. Similar DROP1.4 first 15 days growth in saltwater reef pond. Comparison of all the DROP scrubbers. DROP1.2 and DROP1.2x dimensions. 3.25″ wide x 6″ tall x 2.75 thick front-to-back (8 cm wide x 15 cm tall x 7 cm thick). It requires at least 5 (13 cm) of water to operate in. Operates on both 120 and 240V. 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 DROP1.2 grows well in saltwater with phosphate up to 0.4 ppm, and the DROP1.2x up to 0.5 ppm. They both grow well in freshwater of even higher phosphate, and are the largest DROPs recommended for freshwater. The DROP1.2 and 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 in saltwater, or a thick green coating in freshwater. 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 DROP1.2 or 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 units are also good for backup. The DROP1.2 or DROP1.2x will fit into any size aquarium, sump, and many 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 DROP only need 3.5″ width.. And of course it can fit into the display (the main part of the tank). You can keep it suspended above the sand (slightly above the water surface) so it will run quietly, or you can set it on the sand/gravel bottom (so that bubbles come out and circulate the water) because the DROP1.2 and DROP1.2x have a special plate on the bottom which allows it to sit on bottom without letting the circulation holes get covered up. The DROP1.2 and DROP1.2x have water inlets and outlets at the bottom of the growth compartment, where internal upflowing air bubbles inside the unit (from an air pump which you provide) flow up into the growth compartment and bring aquarium water inside it. As the water enters the growth compartment, it mixes with the air bubbles, and rubs the algae-attachment Green Grabber textures, and gets blasted by the super-red 660nm LED light. This rubbing of bubbles causes algae to start growing on the rock hard (and heavy) Green Grabber textures; freshwater grows thin stringy slime algae, and saltwater grows thicker, denser algae. The air then goes out of the top of the unit, and the water goes down and out the bottom, without many air bubbles remaining. If you position the top 1/2 inch (1 cm) of the DROP above the water, it is very quiet and all bubbles are removed. The Green Grabber algal growth attachment surface is so rough and prickly that it might be the roughest thing you’ve ever felt. A cactus might be sharper, but that’s about it. Rough surfaces are critical for allowing algae to attach and grow and thus provide strong absorption of nutrients. The rock-hard protrusions stick straight out 1 to 3 mm. Previous algae scrubber screens were made from “slippery” plastic canvas that is used for sewing and knitting; algae take a long time to attach to it. Green Grabber growth surfaces are not plastic at all; instead they are rock hard and have jagged rough edges and points (don’t let children play with them). And the white color of the Green-Grabber surface reflects as much light as possible, allowing lots of light to reflect back to the algae. Light = photosynthesis = filtering. The main advantage of the DROP1.2 or DROP1.2x or any algae scrubber is that if you size and operate it properly (based on how much you feed, and how much problem rock you have), 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 is also dry-out proof, since it’s always under water. Power outages will not affect it. And very important – it cannot overflow onto your floor! The DROP1.2 or DROP1.2x. Both 120V and 240V. And comes with a 10 ft (300 cm) UL and CE approved power adapter cord with a U. If you require a different plug you can get an adapter at any local hardware or travel store, or online, or you can cut off the U. Plug and install your own plug from a hardware store. It is a simple 2-wire plug, which is also the same as a laptop power supply cord. The power cord is actually the same as a laptop computer cord with a C7 connector (looks like a figure eight), so you can swap your laptop cord with your DROP if you want to. The DROP uses a low voltage that is perfectly safe. The LEDs are sealed in a triple waterproofed manner; this prevents corrosion from fresh and saltwater. The UL and CE approved power supply works on both 120 or 220 volts; it converts (and isolates) the 120 or 220 volt mains to the safe low voltage which is isolated from the water, meaning that even if the LED were not sealed at all you could put the LED into the water and it would continue to work and nothing would happen. It is recommended that you use a GFCI safely plug, available at any aquarium, hardware, electrical or home improvement store, or online. Comes with 3 ft (90 cm) of vinyl airline, but requires an air pump that can pump at least 2.0 liters per minute. 07 cfm, preferably more. A pump that says it can handle 2 or more airstones/outlets, or a pump with 2 tubing attachments instead of one, will be needed. You can have as much air as you like, however; 10 lpm pumps are no problem (although it will be louder). One powerful pump is the Whisper AP 300 from Tetra, although you may prefer a pump with a control knob to reduce air flow. With any 2-outlet pump you will need to combine the two outputs into one to feed the scrubber, using something such as the “Tee” air line tubing fitting from Tom Aquatics. Make sure to put the air pump above the aquarium so that it will not drain any water if it shuts off, or use a one-way valve on the airline if the pump is lower. The DROP1.2 has. Three red (660 nm) 3-watt LEDs. Which are triple sealed in epoxy. The DROP1.2x has. Four red (660 nm) 3-watt LEDs. Which are also triple sealed in epoxy. Almost no red light comes out of the bottom holes, because they are covered by the special plate; a little dot of red light comes out of the one hole in the top, which fish start associating with fresh green algae to eat. Need to get a timer. So you can run the LED for up to 22 hours per day (not 24), although you can start off without a timer if you’d like to. The LEDs never needs replacing. The DROP will need to be cleaned (“harvested”) every 7 to 14 days or when thick with growth. Just lift up the DROP out of the water, open the hinged lid, and pull the algae out (freshwater will usually require taking the filter to your sink so you can clean it with a toothbrush). You can even feed some of the algae to your fish, and there will probably be some some pods inside that you can feed too. The DROP1.2 and DROP1.2x come with a.
