activated carbon a superior high-purity bituminous coal-based activated carbon preferred by public aquariums research centers and government fisheries departments the small particle size of 1/16 to 1/8 1.7 to 4.7 mm exposes more adsorption surfaces for maximum utilization keeps water crystal clear adsorbs full range of organic contaminants pesticides odors colors chlorine dissolved organics ozone and many heavy metals carbon is dry packed can be retained using window screen size screening the 15-lb plastic bucket has a resealable lid approximately .625 m2 of surface area per gram bulk density is approximately 24 lbs/ft3 cannot be shipped by air made in usa each 3 techno carbon by prolinetm this pellet-shaped carbon adsorbs ammonia and nitrite in addition to what normal activated carbon adsorbs not to be used in place of a biological filter but as a supplemental method for removing nitrogenous waste can be used in both marine and fresh water each 4 mechanical filtration filter media 238100 2.2 lbs 1 kg 238200 18 lbs 8 kg 13.80 68.60 13.11 65.17 ac412a ac412a ac412 ac55 1.5-lb jar 15-lb bucket 55-lb bag 9.95 9.04 78.00 70.20 138.00 124.20 238200 238100 sinking beads you asked for them so we found them use these sinking beads as a replacement for sand in sand filters or use them in a fluidized bed or as inert hydroponics media these beads come in assorted colors no choice and are sold per cubic foot weight is 52 lbs dimensions are typically 1/16 x 1/8 in an oval shape when used in sand filters backwash water flow should be reduced as beads fluidize easier than sand beads have a specific gravity of 1.7 sand is 2.0 to 2.8 ab145 89.00 80.68/6 iron-out iron-out is a glauconite-based greensand that works in a filtering system to reduce iron manganese and hydrogen sulfide it provides reduction of these minerals through oxidation and precipitation then the precipitates are removed through backwashing one cubic foot removes one ppm of iron per 10,000 gallons one ppm of manganese per 5,000 gallons and one ppm of hydrogen sulfide per 3,000 gallons before regeneration is required using 4 oz of potassium permanganate this sand-like material works best within a ph range of 6.2­8.5 and maximum temperature of 80°f/26.7°c it is ideal for use in sand filter vessels see index mesh size is 18 x 60 effective size .3 35 mm and flowrate is 10­12 gpm/sq.ft sold in one cubic foot bags made in usa · each 4 gs11 ptp5 iron-out 1 cu.ft 85 lbs potassium permanganate 5 lbs 88.65 32.70 81.56 30.28 gs11 floating beads similar to above but they float these elliptical polyethylene beads are about 3/16 in diameter with a .92 density sold in 55-lb 1.65 cubic feet packages not recommended for sand filters ab1 100.00 89.88/3 iron-out greensand close-up ptp5 important we have tried to make this catalog as comprehensive and factual as possible however we reserve the right to make changes without notice manufacturers specifications may have changed since the date of publication tech talk 46 if iron is in your water you can either move to another location or spend some effort to remove it the presence of iron above .1 ppm is considered detrimental to most freshwater fish-keeping 5 is lethal iron-bearing water when fresh out of the ground is usually clear because iron is in the soluble ferrous iron form as soon as it reacts with a little oxygen 14 ppm per part of iron the iron is changed to the ferric state and turns brown or orange then it either drops out precipitates or remains suspended as a colloid there are three general classes of iron-bearing ground water 1 those that precipitate immediately after aeration 2 those that do not precipitate acid waters 3 those that precipitate only part of the iron iron removal to remove iron that precipitates readily simply aerate or spray water into the air using the well pump s pressure hold the water in a settling basin followed by a slow rate sand filter of about two gallons per square foot per minute for removing more difficult iron the aerated water may be passed over coarse contact media lava stones coke etc in a multilevel tray the media soon becomes coated with iron hydroxide which promotes catalytic precipitation of iron and manganese from the water all three classes of iron can be removed by the lime-softening process and/or the zeolite process sometimes called greensand 272 order online aquaticeco.com order by phone 877-347-4788 tech support 407-598-1401
