Can imagine being wiped out. Cleaning and filling some tanks with gravel is a pain.... xxxxx <edited or I'll get a 'grammar' correction again...lol>
Doing two tanks is more than enough for me. Can't even phantom your back trying to do more with all the tanks you have.
Will still work on my MTS-syndrome though, sure the wife won't mind...lol
Looking forward to the progress-pics.
Cheers.
