I have a 15 x 15 cm tank (yes, it's true) and I was wondering what's the easiest way to light this. The regular clip-on spotlights for PL bulbs can't twist very well; the bulb ends up outside of the tank rather than directly over it.
I've noticed my mushrooms losing color. I use a 14w PC 6500k lamp in my 1.5 gallon tank. Would love to put in a blue tube, but actinic doesn't come this tiny.
After 3 weeks closed up in my tank, it opened, but the polyps were all white.
And that's the way it has been for the past 3 weeks. But the thing is, even though it's white, the pink mat is spreading.
How can I get the color back? Is it even possible?
