My name is Jim/Falsedawn user name, gaming moniker. I'm a 54 year old English teacher about ready to retire. I used to have several fresh water tanks in my youth and today I have put together a salt water, 90. Gallon, wave tank( customed made). I have everything but a skimmer, t5 led, chiller, plus need more cured rock. I'm using a 505 flugal temporarily with 4 damsels and 20 pounds of cured rock. My tank chemistry is spot on. Just a fluorescent light for now. Fish very active, seem content! I do have a question. Can I introduce quartz crystal rock for decor to my tank without a negative affect on chemistry? Thanks, Falsedawn
