                                                In the latest issue of Aquarium Magazine, I came across this information: As in freshwater aquariums, in marine aquariums, both green and red macroalgae require regular fertilization. J.H. Tallock published a recipe for a two-component fertilizer in the American magazine "Freshwater and Marine Aquarium," which largely solves the problems with cultivating marine vegetation: Solution A: B1 - 2g H -10mg B12 - 10mg Solution B: Disodium phosphate (NaH2PO4) - 4.26g Iron citrate (FeC6H5O7·2H2O) - 3.83g Manganese chloride (MnCl2) - 0.2g Sulfuric acid (H2SO4), sp. gr. 1.83 - 0.5ml Distilled water - up to 1 liter The working solution is prepared by mixing 99 ml of Solution B and 1 ml of Solution A. Add 1 ml of fertilizer per 1 liter of water in the aquarium. With each water change, a proportional amount should be added. Initially, this remedy was tested in the 1980s in Moscow in the aquariums of D. Stepanov and O. Shubravy. When using the fertilizer, one should not forget about lighting. Cultivation is best carried out at an illumination of 16,000 lux. The quality of water in the aquarium should be maintained at optimal parameters. As experience has shown, the specified solution is suitable for growing Caulerpa (prolifera, racemosa, mexicana, etc.), Ulva, as well as other algae - Cympolia, Rhinocephalus, Udotea cyathiphormis, Penicillus spp., Udotea spinulosa, Halimeda spp. Kochetov.
