I just wanted to post up my latest D.I.Y. project, Poor Dads Auto Doser. What your looking at is 1000ml IV drip bag that contains a weeks worth of fertilizers running into my 90gal fish tank.
In the bag I have Bightwell Aquatics: FlorinMulti 9ml, Florin-K 36ml, Florin-Fe 36ml, FlorinAxis 9ml, FlorinGro 36 ml, and BlackWater 22.5ml. I added distilled water to increase the volume total to 1000ml, the bags capacity.
I have the bag dosing at 2 drips per minute. This will give me a slow amount of fertilizers feeding into my tank over the course of seven days. I'm trying to mimic natures slow release into water bodies and reduce algae related issues.
My fertilizers totaled up to 148.5ml. I added the capacity difference with distilled water to fill the entire capacity of the bag, 1000ml. Since I added a weeks worth of fertilizer, I divided the total capacity by 7 to equal the amount I needed dosed into my tank daily which is 142ml. Using drip rate formula Volume X Calibration over Rate(minutes). Note, calibration is how many drips it takes the IV to equal 1ml. 142ml x 20 over 1440minutes (24hrs) equaled to 1.97 drips per minute.
