Use Botanicare Clearex Quart to correct the most common cause of crop failure - the buildup of nutrient salt deposits in soils or soilless grow media. High salt concentrations in media can cause the shrinkage and death of plant cells due to the excess draw of water through cell walls, and eventually lead to the irreversible wilting of plant leaves and stems. Periodic flushs with Clearex will remove excess nutrient salts and safely leach them from your crops media.Botanicare Clearex 32 ounces

This is one of the few additives that most aquaponics professionals agree needs to be regularly added to most aquaponics systems for the treatment and prevention of yellow leaf (Chlorosis). DTPA is the best form of chelated iron because it is 100% effective from a pH of 6.0 - 7.5. Directions: Iron levels in an aquaponics system should be at 2 - 3 ppm. You can measure this using an iron checker. If you don't have a Checker and are just responding to yellowing leaves then we recommend adding

Some companies make cheap, inferior pH adjustment products that never achieve consistent results; some of those
