My second question is about lighting. iI've read that I need about 10k Kelvin and 7-8 watts per gallon lighting for hard coral and soft coral requires a more yellow light. Can I run a soft coral tank with the same lighting as the hard coral or will this hurt the soft? Thanks in advance for any help!
By filter tank do you mean a sump / refugium? If so then yes, it can be done. It will just require some serious plumbing and water pumps to make it happen. You could go a few different directions here imho
A mixed reef would work with both hard and soft corals together. It requires some creative placement but it can have very nice results. On the other 55g tank I would do a FOWLR
tank to have some more variety in fish. This wold work nicely because you would save some money on lighting 2 different reef tanks.
A 55g Soft and a 55g stony coral tank would work well because you could have specialized setups that are geared towards the specific species. This would probably be an easier setup than the mixed reef because you wouldn't need to specialize placement for them.
55g mixed reef with a 55g sump. I like thi idea because it would give you super stable water parameters and lets you concentrate all your effort into one single reef tank. A 55g display refugium might be a good addition.
From my experience, my mushroom corals as well as my finger leather coral HATED a more yellow light. I had let my actinic blue and 10000k light go for too long without a replacent and wasn't getting the par levels I wanted so I switched them with a 6500k and a 10000k light. They were not happy at all with the change. My zoanthids didn't really care
