75g reef suggestions......

[jon s]

Hey Guys have recently changed direction on my tank from fowlr aggressive to reef after an unfortunate weather/heat related incident with my tank anyway here is what I have. Looking for suggestions to add a few more items to the tank over the next few months. Current set up is 75g with a 29g refugium set up with a HOB overflow. I have about 75-80 pounds of live rock in the DT with a 2-3 inch crushed aragonite sand bed there is also about about 20 lbs or so in the fuge with a big wad of chaeto and an knch of live sand I currently have a fluval 405 set up with bio balls and chemi pure elite as well as a a CPR bakpak2.
Current tank inhabitants are a large 4-5inch GSM clown, 3 1 inch blue/green reef chromis one 3 inch or so Kole tang and a 3inch eel coral catfish also have 7 nasarius snails, 2 black and orange legged hermit crabs, and a sand sifting star. I need to add a few algae eating snails and would like to add a few soft and easy corals as well as an anemone a second gsm clown i know its a crap shoot and i def need to go small and maybe a rusty angel or a fairy wrasse. Good...bad....other???
Tank had been up and running for 5 years minus a two week period with hurricane sandy that wiped out the whole tank last fall since then I relaunched the tank and it has been doing well. 0 ammonia, 0 nitrites and

What is your lighting setup??
This is going to be the big difference between what you ran as FOWLR to a Reef.
All your other equipment sounds like it is working well, and should continue to do the trick running a reef tank. Keep an eye out for the bioballs and canister filter. They can turn into nitrate factories if you don't keep up on the maintenance (I would suggest at least monthly cleanings, or more often).
As long as your lighting is sufficient you should have no problem keeping some soft coral. An Anemone is a different story. You need very good lighting for Anemone's, were talking MH's or a 3 watt diode LED fixture. For a 75g tank your looking at spending $300+ for lights to support an anemone (that is for the low range of light fixtures, you could spend over $1000.00 for a premium fixture). But if you decide to go this route, you will be able to support almost all light hungry corals as well.
I am not sure what you mean about your buffering and hard water. Do you use RO/DI water for water changes and topoff's?? If not, it is recommended.
As for stock... It seems to me that you are just about full. IDK how the current clown would accept another clown. You maybe able to add the dwarf angel. But then I would say full.

Oh yea sorry about the lighting omission i currently have a dual t5 running blue actinics they are 32 or 34 watts each I think also have an led fixture with 90 3w bright white daylight bulbs the lights are very bright I was thinking of going with one blue and one purple t5 to change up the light spectrum more favorably toward corals but need to research this more hope this helps answer any additional questions that may crop up
