Here is an update of the 20 gallon tonight. Few changes going on. Ludwigia palustris is out, new background happening. L. Repens rubin far left, Ammania senegalinsis center, and just planted the right back ground with Limnophilla aromatica, see how it does for me. Added a Rio 90 pump to the tank improve circulation, it helps alot. With the tank so dense with plants I was not getting that great a current low in the tank, even with running a fluval 204. I'm not sure if I like the Brazilian micro sword foreground. It's filling in slowly, think it might be a bit tall. Got to give it more time. In the shot of the Limnophilla aromatica you can see the algea on the E. tennelus and the crypt leaves. No matter what I do as far as dosing and lighting, this algea will not go away. Hoping that consistent C02 levels with pressurized will help. The plants are quite old, maybe it's just time to replace them with fresh ones, or do a good pruning of the old leaves. Learning as I go, not sure how long aquatic plants will live and look healthy, coming up to my one year planted tank anniversary! I think you need to replace old plants eventually even in a healthy tank. What do you guys think?
