I have one for you, its becoming a pet peeve of mine.
"But salt water tanks are too hard, nanos are even harder and pico is for expert only" No they aren't. I dunno, but I've had my tank for about 3 weeks now (give er take) and its only a little 5g tank. No algae issues, coraline growing, corals growing (granted I bleached em, but they are slowly coming back) and all the inverts are fine. I dunno what the heck they are talking about hard. Hardest part I've dealt with the SG rising because of evap.
