Odds are with predatory fish nitrates will never be 2 ppm more like 20 - as for algae eaters don't worry about it if you don't have an algae issue as algae species are eaten by a-specific hermits and others i.e. lawn mower blenny's don't eat every variety of algae.
Yes zoas can live in standard salt mixes. Using salt mixes high in alk stuff can be detrimental if nothing in the tank is reducing it's totals - instead it will build and ph will climb higher as alk stuff is an acid.
Lastly w/c's help replenish h20, trace, and dissolved sodium as well as numerous alk materials to help stabilize ph. It also manually removes nitrates phosphates, tds, and co2 in small amounts. Obviously the larger the w/c the larger amounts removed however there is a point where removing too much water screws with the chemisrtry.
I would strongly recommend the frequent use of testing kits to guide you thru the initial cycle process and beyond
Alright so as far as algae goes I'll cross that bridge when it comes I guess. Is it at all realistic for me to expect the Macro Algae to consume a reasonable amount of Nitrates? I know in Freshwater, plants don't really change anything unless you have a ton, or you have something like Pothos hanging in the back of your aquarium. I have no idea if the algae can actually make a difference in Saltwater though.
Do I need to worry about all these water chemistry things you mentioned or would that be only if I was to use the Reef Salt?
Make no mistake I will be testing the water daily, more for my own curiosity then anything. If everything tests safe then within a week or two I'll be getting a small little damsel just to help keep everything going and have a source of ammonia. Everyone says Damsels are bad for your first fish, is that something I should worry about at all or is that only for reef/nano set ups? I can't imagine a damsel picking on a lionfish or eel, or at least not a very smart one haha
Update wise I won't be able to get the stand until Thursday now so everything else is delayed until Friday evening. I'll try my best to take lots of pics and not get too caught up in excitement!
