and this is just going to get worse.... Al gore told me that by the year 2015, your 20 nano will require a 1/3 hp chiller.....in winter! can I get carbon credits for growing macro algae or do I have to buy them?
oops, sorry evaperation works great, just remember you are going to have to top off a lot more... do it daily... it is not nice to change your SG by 10% all at onnce (about 10 gal in a 100 gal tank ~1 weeks evap with a big fan)
