Sorry,
Green water ate me alive after I rescaped the tank. That is what I get for using unestablished power filters with very little biomedia.
I made a canister filter and things are perfect now but the plants have not been scaped. I will do that in the next few days. Rocks and wood will be rearranged a little but I want to still keep that same "passage" layout because it seems hard to grasp and I want to learn.:-D
Thanks for the interest, updates to come!
