Hi Hoppy! I just need some clarification on my lighting! What type of lighting level for plants would you call this ? Two T8s, 36 watts , 17 inch high tank (Luminaire sitting 2" Above tank, Glossy white paint at the back of the bulb), 30" length , 14" width. 4"substrate at the back 2" at the front?
Bromothymol blue by itself isn't going to work. The test reagent contains a little more than that, but the dye is bromothymol blue. API pH test kit reagent is the right mix to make this work. Or, any similar pH test kit reagent, as long as the color chart for that test kit shows that yellow is about 6.0pH and the darkest blue is about 7.6pH.
I recently made a dropcheker reference solution from one of the guideson PTN and I tested it and it was spot on. THe problem is when I add it to the bromethyl blue it turns instantly black/green and then in my tank it moves to a yellowy green orangiesh is this possible? did I put to much blue in?
I hope that I did not upset you in any way through my arguments. That certainly wasn't the intention. All I'm trying to do is defend an alternative way to find an estimate power requirement for a new light fitting that matches a required PAR criterion.
thank s so much hoppy, you dont know how much your help means to me. I've been into freshwater for over 30 yrs, and this lighting crap with all the myths gets aggrivating. I've only recently started to try to grow more demanding plants. I was a Cichlid breeder for about 15 or so yrs and cou[dnt keep anything but java moss and java fern.
