Greetings all, I've had a 25 gallon saltwater tank for roughly 6 months now and it's been a pretty smooth experience so far. I have nearly shell-less snails?/slugs?, live rock, aiptasia polyps, a long spine sea urchin, a neon dottyback, and a blue damselfish. Chemically speaking, the numbers for the usual tests are all pretty good, besides nitrates being a bit high. The highest it got was 60 ppm several months ago, but getting a skimmer lowered that to an average 40 ppm. It's still a bit higher than I want since I'd obviously rather not have much algae, but didn't know what the safest way to reduce it would be besides water changes and vacuuming. I got a bottle of Instant Ocean's Natural Nitrate Reducer and just didn't know if it was A) safe for the contents of the tank and B) worth taking the risk to use for that nitrate level. The website nor any other searches implied reason to be worried about the safety, but I'd rather not do any damage. Any suggestions or help is appreciated!
