Hi guys I'm newbie and mind asking some questions?
1.) What are the differences between T5,T5HO and T8?
2.) How many watts do I need if I were to form thick and dense glosso carpet in 2 feet tank?
3.) Does diy co2 provide the same co2 to the tank?
4.) Is 360lph flow rate good for 2 feet tank?
Would be happy if any sifus can help out..

Hi,
1.) What are the differences between T5,T5HO and T8?
Like master Weijie said, the technology behind it. lowest to highest in terms of intensity: T8, T5, T5HO
2.) How many watts do I need if I were to form thick and dense glosso carpet in 2 feet tank?
if using T8, for a 15 us gallon tank, min 23 watt to max 30 watt without using CO2.
at 31 watts and above, CO2 is a must.
The higher you wattage, the faster your plants will grow, thus more CO2 and more fertilizer.
3.) Does diy co2 provide the same co2 to the tank?
it will provide co2 and as master Weijie said its troublesome. Additional note, diy co2 will not provide consistent CO2.
CO2 inconsistency will aid in algae outbreak.
4.) Is 360lph flow rate good for 2 feet tank?
Assuming 2 feet tank with 15 us gallon volume, minimum for a planted tank times 6 = 90 us gallon per hour.
for heavily planted tank up to 10 to 12 times filtration. 150 us gallon/ hour to 180 us gallon/ hour.
Hope that helps.

to both masters.. make peace/love not war...
