I had tested all my water, in my 125, and the readings were all at 0. The problem is, I never saw ammonia or nitrAtes spike. My nitrites were at 0, along with everything else. Well, I though this was very odd. I went to the LFS
to buy a small fish for my 125 (later to be moved to my 20G). On a hunch, I took in my water, just to test. Well, the nitrites were at .25ppm, at the LFS
...I was a little upset, but no big deal. I decided on geting some LR
instead, just to add to my tank. I pulled out one piece and foud a brittle star! I called the LFS
(they don't give discounts or anything like that), but I told them I would pay for it the next time I was in there. Anyway, the whole point is sometimes you just need to doublecheck your water/tests....just in case. I ended up putting the brittle in my 55G, I doubt he would have made it in my still cycling tank.
