The 30" deep is a blessing and a curse. It's a blessing because it looks so cool having such a large viewing area in the front.
Its a curse because you cant reach the bottom of the tank....unless you got long arms. I dont.
I had to rig up some long PVC pipe with tongs on the end just to be able to set all my plants in the gravel. Plus I had to add an extension to my gravel vac to reach the bottom.
But all and all, I am glad I made the decision to go with the 300 gallon.
I love it.
Good luck with your's and hope you post a slew of pic's to document your progress.
