I'm buying my new tank on Saturday. Only 38gal/144L but I'm still complaining. Nah it'll do i suppose. 36"x14"x18" on a pine wood stand. I'll have to stain and vanish the stand first mind you so it'll be a few days before I can properly set it up. I'm going for a really fine gravel and will transfer most of the water from the other tank and the filter, so I can cycle that quick and also change the gravel in the old tank to the same fine stuff for the corys etc. If I did this would that mean the new tank will be instanly cycled with the transfer of the old filter and most of the water? because I was thinking of movin the fish before I change the gravel in the old tank. Just momentarily.... Any thoughts/suggestions ???
