That seems like a lot of work just to tear down in 3 months. But it is going to rock for those 3 months. Are you going to be doing any regular fert dosing or CO2 of any sort?
I wanted to practice so when I get to my next base I would know what to do. I also didn't want a tank sitting there empty. I will do ferts and DIY CO2 for the moment. Hopefully some time in the next 4-6 month I'll have Pressurized CO2.
