Hi all, anyone know what this is? Hair algae? Diatoms? This was a freshwater (goldfish) tank before I recently bought it. I’ve filled it with nsw and added a bit of live rock. All my levels spiked at the start of the cycle, and now my ammonia is nearly 0, but nitrites and are 10 and 20!!!! This hairy brown crap has been all over the back of the tank since the first day.
Any thoughts what I should do here? Should I rip out that 3D background? Thinking maybe there’s a lot of old detritus trapped behind it. Although it’s very well siliconed in.
Any help would be very appreciated!
