Thank Ian for your input.

I made some modification to my plans...

- I don't mind pruning each week...more important...less water changes is preffered...
- I should have made a note that I currently have CO2 equipment running...so it will not be an additional investment...i was thinking of getting the CO2 running only during midday...(which both lights come on)...will that work?
- plants...I will want to be able to keep a variety of plants...ranging from rotalas, crypts, anubias, moss, ludwigas, etc...the common stuff.

Thanks.
Barry.
