Thinking about starting saltwater
My wife wants to get a saltwater setup. I have been reading on the internet and it seems to be a lot to take in , but i had a few questions.
I plan on selling one of my guns to try to finance this , and i think i can get $200 for it , will that be enought to get this started?
For now , i just want to do a fish only setup, but maybe want to leave the option open for live rock , coral
I atleast want a 10g , nothing bigger than a 20g. Is a saltwater setup this small even possible , and it is going to be too difficult to keep a tank that small stable enough to be successful?
Is it necessary to have live sand or crushed coral for the substrate? or could i just use Pool filter sand or gravel?
Is a protein skimmer necessary?
Along with testing and cycling the system in the nitrogen cycle, tesing for salinity and specific gravity, what else do i need to test for?
I want to totally understand what i am doing before i even think about going any buying anything to start this. I am going to continue reading the net about all this , and all the help i can get would be great!
