I've had a 10gal invert tank set-up for about 5 weeks now, and cycling seemed to be going pretty well at first, but...I just could not get my ammonia down to zero. I have shrimp in that tank so it's particularly important that the water params be perfect. I've been doing water changes basically every day.
As most of you are familiar with: no ammonia is a bright yellow test tube, and ammonia appears as varying shades of green. So, yeah. The room the invert tank is in has bright green walls
. Turns out the light reflecting off bright green walls can make a bright yellow test tube look greenish. I am such a dork. I didn't realize until I did a test of my tap water and brought the invert tank test tube into the kitchen to compare.
I have no idea how many extra water changes I've done over the past few weeks.
Anyway, now that I've aired my shame publicly: Hi, I'm Jo. I've mostly posted on the betta forums, but I've kept a couple of types of tropical fish in the past and was recently bitten by the bug again. TL;DR:
