Ok, so Is Miracle grow all I need for the culters or do I need to add a bit of essential elements too? Hey reefkprZ, you said that a 10 gall might not work because I have to cover the top? Do I have to completely seal up the 10 gallon tank? If so, why? Can I use a power head for water movement?
I honestly dont know all these answers, But I would think you would want to prevent dust and other airborn pollutants from contaminating your culture. every phyto set up I have seen uses, pretty good preventyative measures to stop contaminants from entering the water. the aqua culture at the local university uses a "clean" room just for culturing of phyto and zoo planktons and the vats (5 feet tall by about 2 feet wide) are fairly well sealed with large airbubbles entering the bottom and exiting a small vent at the top. I can ask one of the aquaculture peole about their set up and the whys, but you may get better answers from someone who grows their own phyto regularly.
sorry I cant be more helpful on this.
