According to at least one person, my son has a "no tech" tank... not even meeting "low" from a plant perspective.
It is a simple 10 gallon tank with a 15 watt fluorescent hood. At present, the plants are christmas moss, java ferns, wisteria, annubias, pennywort, and what I think are baby tears. The baby tears and pennywort don't do well toward the bottom of the plants, but the tops grow very well. The xmas moss is just sort of "existing", not really doing great.
We dose about 0.75ml Excel daily, and about the same amount of Flourish weekly. We do not want to enter a sophisticated dosing regime, nor do I want to deal with CO2 in this tank.... it would, however, be nice to get a bit more light IF it would help with the growth of some of these other plants. I suppose I could trim some of the taller plants down so that more light reaches the lower portion of the tank.
Anyway, my son's birthday is in about 2 weeks, so I thought about a light replacement, if it is worthwhile.
So, should I even bother? If so, what should I consider to provide additional light without getting into a range that requires considerable dosing and co2?
I should also point out that he wants to get a second tank up and running soon if I can put something together through a combination of garage sale finds and a little bit of spare cash - something not easy to come by these days!
So I suppose a third option is to leave this tank as-is, and deal with increased lighting if/when we can get him a second tank operational and stocked.
