To start the cycle and build bacteria, you need to add an ammonia source. Research the nitrogen cycle. So you're basically doing a fish-in cycle if you didn't add an ammonia source to cycle the tank. The fish are adding the ammonia for you, but it's pretty rough on them. Ammo burns the skin and gills and nitrites decreases the amount of oxygen they get, so they can suffocate basically. It usually takes 4-6 weeks for the cycle to complete after ammonia source is added. You'll need to get some liquid tests for ammonia, nitrites and nitrates at a minimum. If you buy a master test kit, it'll also have pH and alkalinity. You'll need to test every day for ammo, nitrites and nitrates and if ammo or Trites go above 0.25ppm, you'll need to do a PWC
to bring it down. Above that level can kill fish quickly.
That temps a little cold for a marine tank. The temp shouldn't go below 72*F, and shouldn't have big fluctuations in the temp from day to night. It needs to be steady. When you buy a heater, try to get one that you can dial in a temp number instead of one that has a preset temp. The preset temp ones don't generally get warm enough for marine tanks IME.
