Placing two islands in these configurations (at opposite ends of the tank) does not please the eye. try to take the Golden Ration into consideration...place the pieces at these points and the result would look much nicer imho.
I'm with ya. Currently stealing FSS and aquasoil from other tanks to mix in. What so you think would look better. Glosso or HC. I have grown both before. Both nice. HC looks nice when trimmed but it's a lot more work. Glosso is pretty low maintenance and still has a nice effect
Well, that depends a bit on how you intend to run this setup. They both need a lot of light, but glosso can be done without CO2. I'd go with glosso because it is easier in upkeep/maintenance and actually just as nice as HC, imho.
Lower work is nice. I do have co2 so I will prob use it at first to adapt it then either leave it connect at a low does or slowly tone it down until it's not need. I'm doing renos and have about a month before I can actually set up the tank. Which is why I have been itching to get a DSM going to prep it
