I have the exact same tank, but mine is seriously low tech. No co2. I'm actually gutting the tank tomorrow and putting down a substrate suggested to me of compressed coconut hull, top soil, and sand. I'll also be mixing in a little laterite between the coconut fiber and top soil.Hey guys,what would be the better option for 28gal bowfront(pressurized co2 and fert):
- two T5 NO (56w total) or
- one T5 HO (48w)?
Wow! That seems like a LOT of light. Maybe with the co2 and ferts it's ok, but even a single light HO fixture will give you high light conditions for that tank. With about 3 inches of substrate you're looking at about 17" from the lights to the substrate. I'm looking at maybe getting a dual HO for mine and dimming the light a bit by using some screen like Hoppy suggests. Plus the HO bulbs are more energy efficient so you're saving on power consumption there.Its two T5NO fixtures-two bulbs each- (4x14w) vs one T5HO fixture -two bulbs-(2x24w)
No, all light penetrates equally well, when we talk about white light. Water doesn't absorb enough light to even worry about until you get around 30 inches in depth. Granted that it absorbs red much more than blue, but at 20-24 inches deep, like most tanks, there is no point in even considering "penetration" of the light.+1
And if you have plants on the bottom, the T5HO will penetrate to them way beter than the T5NO will.
