sweet for a first setup, as was said before , plenty of filteration / circulation is needed ,as per your critter listing , minced seafood for all the livestock (hand fed to the anemones) , and place tank in the coldest part of your house until chiller installed, rockpools vary in temps massively from cold to over tropical temps and salinities so your collecting from the hardiest points of the ocean life forms.. you can have chiller blocks floating in the current to keep heat down until chiller unit installed... have kept numerous NZ marine tanks when in Tauranga and all from exp with sea horses, octopus , stargazers, leather jackets , kelp / marble fish, mao mao , pipefish , crabs & shrimps of all types, anemones , sea weeds , sponges , etc etc blah blah... ... so keep up the good work ....
