ok meg, ill say this and not to be mean or rude, you get alot of the comments cause you are asking questions and getting opinion's and answer's, they seem not to be the answer's you want to hear, but they are the correct answer's. my best suggestion for you is to instead of spending money on fish corals ect, buy better equipment, look at where you want your tank to be in a year from now and see what equipment you will need to maintain a healthy and beautiful tank, throw the api test kit away, there junk. also get rid of the hydrometer and get a refractormeter. i am saying most of this stuff coming from someone who didnt listen and read enough and look enough when i first started the hobby and oh lets say $1500 later in lost fish and corals i have now learnt what it takes to have and maintain a healthy reef tank. even though urge's still come i refrain from impulse buying. patience is a virtue in this hpbby, like keeping your hands out of the tank use to be the hardest thing for me to do, but after seeing the differance from keeping hands out and the improvement im happy. there is alot of knowledge to be gained from the people here, some of the member's on here are not just known on this site but known thoughout the hobby and respected in the industry. be patient, listen, read and happy reefing, p.s you can always read through other people's tank log's, see what they are using equipment ect and methods
