I like your 10G. I just read through the whole thread and got to see the progression. It looks like it has come a long way.
I'm just getting into planted tanks myself. you can check out my thread in the Signature below. If you visit it, you will see that I'm a newbie that has been asking tons of questions.
I like that diffuser, I need to get one for my tank.
Anyways, good luck with your tanks. Where is that ADA tank you bought a while back. Hope it's coming along!
