For anyone who wants to answer: If I wanted to upgrade to soft coral later on, aside from lighting what would be the most important for me to upgrade? Like should I get a bigger filter, powerhead, or protein skimmer, etc.. Just feeling like if I'm going to be investing a bunch in water overtime, I should consider improving other things in the aquarium.
As long as live rock is properly cured, you shouldn't have to replace water. With uncured live rock you actually will have a fair amount of dead and dying organisms and a complete water change is in order.
I don't think distilled water will be a good choice, I would stick to RO for inverts.
Ok thanks. I'm not sure where to get RO water. I'll check with the place I was planning on buying the live rock from if I can't find it anyplace else.
If I just went with a clown goby would RO be as important? Either way I'll probably go with the RO so the aquarium isn't as empty. Since my aquarium is so small, not sure if it would really be cheaper to buy a RO setup at this time than buying RO water from stores. Or at least it probably would take a year to just break even.
