I usually recommend pico salt water tanks for advanced salt water enthusiast as things can change fast and you will most likely have to use a chemical filtration such as chemi pure elite,GFO, or phosgaurd mixed with carbon to achieve success not to mention some good old water changes.On that note I like fluval planted shrimp tanks alot but I do also like nano zoa gardens.I suppose I am not helping with the decision making here,maybe some one else will chime in.I wish I could get a PAR reading on one of those little edge LEDs,just to put my mind at rest.
