Liquid ferts concentration (made my own)
I haven't seen a how-to come up in awhile, so i figured I'd share.
I've always dosed dry ferts. Originally I'd mix them in mugs (irons separate) with tank water, but shortly began dumping them directly into the tank. Scooping out doses for 4 different CO2-injected tanks per week was getting old, so I decided to go with liquids. I wasn't sure exactly how concentrated I could make a liquid ferts formula, so I started (using a dosing bottle with a 1oz doser) with 1oz as the dose for my main, 30g high-tech tank. I was able to completely dissolve a basic dose, per ounce (tweaked suggested EI dosing for 20-40g tank), of:
1/32tsp GH Booster
As per recommended EI dosing, 1oz will be added to the tank 3x per week. Chems were dissolved into distilled water. Next time I'll increase the concentration a bit. I wasn't sure which chems might have difficulty dissolving, and at what concentrations, so I started with something basic. I have two 32oz dosing bottles, and the CSM+B (1/16tsp) and iron chelate (1/32tsp) will go in the 2nd bottle. I'll add a post here if there are any surprising developments.
