Hello Everyone!
2) I'm trying to determine which additives and testing kit(s) would be needed. Something reliable and cost efficient would be great.
3) I have been reading that this system needs a chiller. Those JBJ chillers (JBJ Mini Arctica 1/15 hp chiller or 1/20 hp Nano Arctica Chiller) are just way too expensive. Can anyone recommend something else? Or is the JBJ essential? Also, it seems the mini is the right one for this AIO. Any thoughts from the pros?
4) I still have to buy the live rock. I know I need 1-1.5pounds per gallon. Is it ok to do just 1 pound? Or I shouldn't skimp?
5) I would love it if someone could provide a list of things needed for start up and perhaps a link with simple step by step instructions for initial and on-going set-up.
Happy Holidays everyone and thank you all soooooo much for any possible advice you can offer. I deeply appreciate it
Best Wishes

Welcome to MR! keep researching and asking great questions and you'll like it around here!
answers for you.
2: Buy saliferts. they're the best for the money. Sure you could get cheap ones, but they're not as accurate.
3: For a small tank, you might be able to get away with an in-room air conditioner (why not benefit from the electrical cost as well) If you're still needing a chiller, i bought a used 1/10th for around $300. Keep your eyes open for a deal and you should find one. Just remember that this isn't a cheap hobby. buy quality equipment once or cheap stuff more than once.
4: My first tank was a 15 gallon. I searched and hand picked really nice pieces for that tank. I suggest you do the same. Look for shapes you like, rather than 'X amount of pounds.' When you have the rock the shape you want, stop buying. Rather than buy piece by piece you can buy a bunch and then re-sell the ones you don't. I purchased cured rock because i'm lazy. Now I'd spend less on uncured and enjoy all the life that comes with it. your choice.
5: My short list that you will appreciate later.
RODI filter WITH a TDS meter. Start your tank with RODI and you'll be much better off. having a TDS meter from the start will let you know you're putting 'pure' water in your tank.
Refracometer. Don't buy a hydrometer. Spend the $10 on part of the refractometer.
Top-off system. With a small tank, you'll get really really tired of adding fresh water every day. Even if it's a cup of replacement water every day, it gets to be a chore. I have a litermeter I bought used, and it's the thing I'm most thankful I've purchased. If you can't find a used one (they're hard to come by) and you don't want to spend the cash on a new one, there are many other top-off methods. Do the research.
Set up steps:
Put the tank on the stand and LEVEL IT. DO NOT SKIP THIS STEP! shim the stand, not the tank if it's out of level. (every tank I've set up has been a bit out..)
put your substrate in.
Fill with rodi water, and turn on your pumps and check for leaks. Fix any problems. keep the pumps on.
Add salt. Let it mix for a bit (an hour or so, until you don't see any undissolved) then check it with the refractometer. Adjust salinity till it hits 1.024 or 1.025. Your choice.
Take out 1/2 the water, and add your rock. arrange it the way you like it. (it might take a few tries.)
fill the tank up with the water you took out. cover the rest and use it for your next waterchange.
Test the levels every day until the cycle completes. then add animals.
