This has been dealt with before, but since I stared doing it I learned a few things. You need live phyto and f /2 fertil;izer- the phyto you can get from me or @Yates273 and others here, the fertilizer you can buy on amazon or ebay- you don't need a lot unless you have large tanks, an air pump with some hose a ridged pipe helps, but not necessary, a couple/few bottles and a small grow light and a warm room. buy enough phyto so you can use half for the culture and enough to feed your tank for 2 weeks- I use two1.5 liter bottles, drill 2 holes in the cap- one for the hose, one for air exchange. R/O water mixed with salt to get it around 20. I have the air from the pump at a good bubble- not too slow or like boiling water. I bought an 11w led grow light on amazon an put it in a shop type hanging reflector lamp thing and hung it so it shines sideways into the bottles. when the culture gets dark green I either double it or take half and the double what's left. This is where there is some confusion or difference of opinion. I only use enough fertilizer for what I add to the bottle- some don't add anything- up to you. whenever I double I use a new container and pour it through a net to remove any junk. Whatever isn't in the culture is in the fridge and i shake the bottle daily. @Yates273 feel free to add or correct anything
