Hi
I'm new to saltwater and this is my first saltwater tank, this is my 50 Gallon that's on Day 20 of its cycle, I've used Dr Tims one and only Nitrifying bacteria and ammonium chloride to start my cycle on Day 1, this evening I noticed this white mould looking stuff growing on my equipment such as wavemaker and heater etc. I was wondering what it is. I understand my tank is still cycling due to my readings and there are no fish added to the tank, I will not be adding fish to the tank for at least another 2 weeks or until cycle has finished. If there's any parameters you would suggest I test, then I will go out and buy the test kit, I only have lights on for photos and the lights have been off all the cycle. Many Thanks for any help
