drawnitsud Posted June 9, 2022 Share Posted June 9, 2022 So, first, I bought a Fluval 3.0 for my 29 gallon planted tank. WOW. My tank's lid lights could not even (pun only slightly intended) hold a candle to this. It's amazing all the way around. ANYWAY I looked today and noticed there is an almost oily film on top now. Does anyone know what this is from? I have definitely been under-lighting my tank up until now so I don't know if this is a response to that. I tested the water to make sure parameters were still okay and they were great, actually. 7.2 PH (per usual), 0 ammonia, 0 nitrites and 5ppm nitrates. Also adding a photo on the light pattern I am using now (its just the "pro" tab but my Corys seem to love the added light) Link to comment Share on other sites More sharing options...
