both my tanks get direct sunlight for about 2 hours a day, once in the morning, once in the evening. Whatever comes through the blinds goes right into my tank. Gha.ALWAYS indicates there is too much phosphate, it doesn't matter what a test kit says. The phosphate can be bound by the rock and consumed by the algae therefore getting a false test reading. I worried about a test reading about a year ago. It kept reading .08, so I was using phosphate removing media. This reading refused to get any lower, so I kept using it. The end result was 95% of my acro dying. I checked distilled water and guess what.... .08. I now just read the tank for phosphate. How often am I having to clean the glass? Are there any tiny patches of gha anywhere? This is way better than using a test kit IMO.
The bulbs I have are the factory stocked flouresent bulbs that came with the hood of the tank. It's nothing special. The tank does receive some sun light throughout the day. The brown film stuff growing on my glass, is that cyano? Brown algae?
Nitrates, I picked up some 5% white distilled vinegar. A gallon of it. I'll probably start dosing the tank. Did I pick up the right stuff?
No 10k, no one uses that range anymore. Even if its a 2 lamps unit, they can still get away with an Actinic and a Blue+ or 12-14k lampStill how many bulbs go in, 2?
Get a 10k and actinic 420-465nm (39watts each)
