Does anyone have any tips on protein skimmers please. I have a small 40 gallon tank but its built into a cabinet and I only have 2.5 inches clear at the back of the tank, and 3 inches clear under the hood. I was wondering if there anyone might have a solution?
Anyone any ideas why my yellow tang tends to lose its vivid colour occasionally throughout the day or evening? It goes much whiter/paler sometimes... Thanks
Dave
