I have two photon 24's right now and I plan to upgrade my tank.

What's the longest tank I could get using these fixtures without having to replace or add more?

I figure 60" is fine. Would 72" be too much of a stretch?

72" would work in some cases, but you may have shadowing/low light areas, you would be better off with a third light, or 2 32s. But 2 24s would certainly cover a mixed reef with careful positioning of sps.
