Very nice tank!
I think it may be only a matter of time before you need to supplement the plants with some other ferts. But I guess this would depend on your light. Do you consider your light to be low light?
I'm wondering if the weekly Excel is adding any benefit (it only stays active for a day or so). You could try dividing up the dose and adding a constant amount every day. (Or, you could just keep doing what you are doing... it obviously is working!).
This size tank really has my interest. I think if I were to try it in the future, I might use the sand as you have, but use it to cap a layer of soil. I would think a tank like yours might be perfectly suited to such an approach, as you really wouldn't need to uproot the plants very much. Any thoughts on this?
How often do you trim your hairgrass... and how short?
You have no algae to speak of but I think a few otos would be a pretty cool addition
Keep posting pics!
Ya, I'm figuring that I might have to dose a few times in the upcoming weeks as it starts growing back in, but I can't say for sure yet. The lighting is 2 13watt cfl's placed vertically, and at about 6 inches above the water line. I would consider it high lighting, but honestly, I can't say that for sure either. What I really want to do is check it with a par meter to know the exact measurement, but for the time being I'm just going by reaction of the HG.
I considered using soil as well, but since I haven't tried that method yet I wanted to wait to try that on a future project and instead see how this setup would work with just the sand. But ya, I think it would be interesting to see how this setup would work with soil.
This would be the 3rd time trimming it. I'm doing it about once a month, and I try to get as close to the substrate as possible.
Ya, its looking cleaner right now, but believe me, it had some serious algae issues in the past lol
I'm hoping those days are over though and I can maintain its current look, but we'll see.
