8g Biocube nitrates up

[Shelley]

Thanks to all for posting. I am taking all advice into consideration for sure. Yesterday I took a sample in to LFS for nitrite/ammonia test as I don't have these in my kit. They were zero, as were nitrates.

Six line, yes pinkreef, I've been warned. Was told originally it was a good choice and I did the unfortunate "go with your heart" response as I've seen larger ones of these while snorkelling in the past and just love the colour/shape. After purchase, I was warned and I did more reading. Will not make any moves just yet.

If I did a 75% water change, wouldn't that be a shock to the tank's inhabitants and the establishing ecology?

Thanks for the don't panic advice. That's where I tend to go right now as I'm unfamiliar with all of the chemistry pieces and don't want to be irresponsible or kill anything. As I get used to the tank I think this panic will abate!
