Ok i have an algae problem its dark and hairy but i read a thread a little down and going to treat it with seachem flourish excel and see how that goes, but i think with the water at 30C it deteriorates some of my plants. I have an anubris on a log which thrives and i have another broad leaf plant which goes great. But i also have a plant with white lines on the leaves and it is just deteriorating and falling apart i think from the temp of the water. What plants work well at this temperature?
