Plumbing two tanks together pros? Cons?

[Authentic]

I have a 65 gal DT running for 1 1/2 years,apex reef octopus sro2000 brs doses etc, I am thinking of adding a 21 gal anenome/ clown tank next to it and plumbing them together with a upgraded return pump and new led,pros? Cons?

I actually just finished doing the same thing myself about 2 weeks ago. The cons I have heard were that if you were to get some type of fish or coral infection that it would affect both tanks other than that I haven't heard anything else. So far Im very happy I did it. Good luck

Another bonus is less equipment use as long as volume isn't exceeding the equipment. IE a 150 watt heater would still probably work for both those. (Just works more.)

I'd like to do the same thing though the logistics can be challening. For example I have one large 90/125g stand, and trying to figure out how to best fit tanks between a 55L, 40b, 29g(already has nice iron stand), 9gnano. None of which are drilled so heights become a problem for overflows.
