NPT:
The yellowish NPT s due to yellowish bulb spectrum and the soil was stirred up a bit in the past few month as I kept planting new plants and replanting those floating ones. I have stopped planting and re-planting lately. I have also stopped changing the water for the past 11 days because I was busy with my broken medium tech tank. Usually I do weekly water changes of 50%. I use top soil and Holland sand. You can't see any of the soil because I purposely hide them with Holland sand (I surrounded the tank with sand to hide the soil from being viewed through the glass). There's no filter or any circulation because I have run out of power socket in my power extension.
Medium tech tank:
No, there's no BGA in this tank at all. What you see is probably green spot algae. Sorry that it's not that clear in the photos. Now, I am confused again because initially I have been told to increase the light, now someone is suggesting that I decrease it. This is what I mean by conflict of suggestion - I have encountered it many times when trying to solve this issue. Anyway, I have been setting 6 and 8 hours of lighting in the past - it didn't solve my problem. Now I have increased it to 10 hours 3 days ago I think and 12 hours (started just 1-2 days ago). Of course, I have yet to see any result as of now. Supercoley1, the look of your tank is what I expect out of my narrow leaf ferns but I have horrible looking ones. They all looked like the ones in your tank when I got them from my friend. A few months later, what you see is what I have today.
