I was able to grow a Cinereum and "Mini" without CO2 in this tank. There was a definite stunt in growth, but overall they stayed very healthy and did not melt. Let's see if the others will play along.
+1 I have ban ba wa, parkeri, and cinereum growing in low light with no co2(20Gal) and they look fantastic. no melting, zero. However the one's in my hightech 29gal with co2 don't look very good and are melting. Go Figure :P
This is an awesome thread! Great pics everyone! I've been wanting one of these tanks for a long time now but still no go, so I live my dream through you all! Keep up the great work! ^^
