There is a test kit by Salifert. I am wary of iodine dosing. As I don't have a test kit. That's why I only add 0.5ml every 2 weeks. My one is by seachem..super concentrated.
Get a helfrich. It's a good consideration. After all it will be the first fish in the tank and nothing will bully it around.
Anyway..even if AVA clamps down on all corals..you don't have to worry. Got quite a number of reefers doing captive propagation here. Just that you will be limited to sps and softies..not much LPS.
Salt spray on the tube will affect the light intensity that reaches your tank. It is best to wipe the tube with a wet cloth and dry it from time to time to increase its efficiency.
Hmm..In the wild they have territories that are bigger than those that are available in most tanks. They are only schooling in the aquarium because they are confined. In the wild firefish are found in burrows. It makes perfect sense that their burrows be widely spaced apart. When they appear to be shoaling it's only for a short time and that's when they are feeding.
It also depends on the fish. If they can tolerate one another then it's your luck... I've tried 3 myself..ended up with 1. It murdered the rest in a 4 feet long tank. There was a helfrich in a certain lfs..got murdered by the other helfrichs. They might seem docile..but you will never know when their tolerance towards each other bursts.
3some.. Was wondering why the pistol looked different..upon closer observation, it was the female which i introduced today...wondered if it had paired up with the resident male pistol..will try to observe more during the night.
Sometimes read instructions carefully...it's 4ml of water, 2 drops of the green liquid. It should not exceed one syringe for normal seawater. Unless you are measuring the effluent of a Ca reactor.
