In an established tank I switched to live plants and added AMBULIAS ABOUT THREE WEEKS AGO. the tallest Ambulias, closest to the light turned yellow at the top, then started losing leaves, maybe about a week ago when i added red ludwigias too.
I hadn't done water changes, so did some 10%ers and a 33% recently, but ambulia still seems unhappy. Is the biowheel TOO GOOD and starving the plants of nutrients, and/or the ludwigia are stealing too much o fthem? or is the 13 watt bulb just too weak for ambulia? or isthe black gravel too nutrient poor, compared to the aquarium soils more amenableto plant growth?
fish are healthy...
manual says the fluorescent lowers in output with time, altho the aquarium looks bright enough ...
