very very fishy…

Nitrates are sky high…

Well, here’s the first update with any real issues. For the last two weeks my fish started to die, and I wasn’t sure why because I was very understocked and I’ve been pretty anal about what I do with the tank. Up till this week it ocurred to me to check the nitrates since I’ve been fertilizing with KN03 (potassium nitrate)… I didn’t bother before because I dosed exactly what chuck’s aquarium calculator said using a mini scale so I thought it would be safe. 10.75 grams three times a week.

My surprise… the nitrates were at 60ppm! BAH. They’re supposed to be at 20ppm. It was tuesday – water change day – so I took out and replaced 50% of the water, and yesterday before dosing dry ferts I check the nitrates again. Still pretty high at 40ppm. I did some browsing and apparently those nitrates are harmless to fish… but so far I’ve lost 2 red platies and 4 sterbai cories. 😦

About the Author

My name's Maria, and I live at San Diego, CA. Hablo español! When I'm not writing 100 paragraphs about my fish's swimming patterns, I work at a popular chain pet store's corporate offices being a robot. I also go to college, studying web design but I'm reconsidering my major into marine biology. I wonder why?
