I have a few questions:
My 100 gallon has been running for about 6 weeks now and things are going pretty well so far. Currently I've got 2 percs in there, 1 yellow tang, 1 blue tang, 1 flame angel a diamondback goby and a scooter blenny. I test parameters weekly and get PH of 8.2-8.3, 0 Ammonia, 0 nitrites and nitrates are 10-15 ppm
. (I'm having a heck of a time with the Nitrate test color chart, i.e, "is it more orange or is it more yellow!?!?!").
I know nitrates of this level are okay for fish, but am I going to be okay in the long term for corals? Is 0 just really hard to get to? I know this might be a subjective question but, is it worth doing multiple water changes a week to get nitrates that low?
Next issue: so I get about 2.5 gallons of evaporation a day. There is quite a bit of salt that has accumlated along the walls of the sump (above the water line) and on some of the tubing. What do I do with this? Should I shove these salt crystals back into the water? Or should I wipe away this salt? My salinity is pretty much consistently at 1.024. If the salt that I am seeing is coming out of the tank, and I'm topping off daily with RO
water, how come my salinity isn't getting lower? Sorry if this is a weird question
ALSO, sometimes I top off with bottled water from the grocery store if I can't get to the LFS
. Is this okay???
Thanks for the help guys!!
