Thanks Vader.
I've got the green light from the Mrs. on the MegaTank 150 (lol). It's definitely going to be planted. Right now trying to visualize the mixture of driftwood, plants, etc. Getting a good feel for what grows to what proportions in my 45 gallon.
Family vacation in mid-October. Had hoped to start setup shortly after that, but it may be after January 1.
Before getting started I will post a thread asking for suggestions - all the way from the stand to filters to lighting to plant and stock suggestions. Should be kind of fun to see the different opinions I receive. An overall build thread from start to finish is the plan!
We'll all be subscribing to that thread when it materializes

How long is the vacation and what are you planning to do about tank maintenance/feeding in your absence? Since I set up these more sophisticated tanks in the new house, I have not taken an extended vacation and am not sure how I will react to leaving them unattended for an extended period LOL. Even with the solenoid and the pH controller the 'what ifs' of the CO2 injection still scare me...
