Size is about 63 L ( 18 g cca) .Tanks is old about 3 weeks. I will update new photos time from time. I tested Led light with neon and first result is good. I have 18 w about 6500 k neon light and 4* 5 w led 6500 k . MY plan is put another 3 led with 9w 5000-6500k on front .I use co2 about 2bps and easy carbo. I have little problem with algae on sand and little thread-like algae on some plants becouse to much iron i think. I change 50 % water yestarday for bacground and i put some plant yestarday : Hygrophila sunset maybe and Ludwigia Repens . Algae is stop growing . Are you like it , are you have advice or somethink . ? Are you thinking that will be everythink ok when aqarium will be in biological balance ?
The plants grew in quite a bit in less than a week, didn't they! You should put a background on the tank - maybe white or pale gray, if you want to preserve the "light" feeling from having a pale wall behind the tank.
New update 4.9.2012. For you. I am pretty happy with growing results and i put 2 species of plants on right corner. I am not happy only with substrate i must change it in future
