I have a 90 gallon aquarium with the following stock. Rotalia Rotundifolia, Pogostemon helferi x3, Cryptcorne spiralis x1, Mirosorum pterpus x2. Fish stock is 9 Harlequin Rasboras, and 10 Cherry barbs. I plan on adding another Harlequin, 10 Kuhli Loaches and 3 Honey Gourami. I ordered some plantex csm+b the other week and started adding it in small doses. Liquid equivalent to 1/8 tsp. 50% water change every week. This will be my 3rd week and wonder if my dose is wrong. I've ordered some macros from AquariumFertilizers as well as an extra graduated dispenser bottle. What dosages should I be looking at? I wouldn't mind lowering the dosages so I can do smaller water changes. I don't have a python so it's a pain to do. Advice would be great.
