which tank?

[Saltwatercoral2]

I have 2 tanks that are just sittign collecting dust. So i figured i would use one. Which tank would you go with?

40 gallon breeder 36 x 18 x 16.
or a
58 gallon 36 x 18 x 21?

The breeder tank is already drilled.

 

[Reefers Digest]

40 Breeder Pros: Already Drilled, Shallower (Better Light Penetration)
58 Gallon Pros: Larger Volume (more stability), More room for fish+corals

The winner?: Both. Depending where the 40 is drilled...

Bottom: Use as main tank with 58 gallon sump/refugium
Side: Use 58 as display and 40 breeder as a sump with some custom plumbing.

Stable (98 gallons) and you have either a shallow display for higher light levels, or a larger display for more inhabitants/rock.

All the equipment will really be the same.. I just need to decide on a tank. Im leaning towards the 58 as it has a little more room. Just need to drill it and im a little scared never done it!
