There is no point where you "need" to use high lighting; it is a matter of what you ultimately want to do.

Higher lighting means that your aquarium will be higher maintenance; there will be a need for CO2, fertilization, and regular pruning, etc.

Lower lighting means lower maintenance.

Without your light specifications, it is hard to determine how much lighting you have.

I would take a look at Hoppy's very informative thread here.

here is the specs that you needed

as of right now i am running 2x T5HO 39W 36" bulb on a icecap ballast with tek2 reflector's, my tank is a 40B tank at 36"x 18"x 17" and only 30 gal of water when everything is setup and water is added... fixture is 23" from substrate to light and i keep my lights on 9-10 hrs a day every day on a timer..


also talked to hoppy about it also but was just wondering about the high light thing... if i wanted to go all out on plants (half my tank is covered in plants) would it still be low-med light or would it be consider a high light tank?

Your current lighting would squarely place you into high light (or more).

Depending on plant mass, you may have (very) high light at the surface, but low(er) light at the substrate level (i.e. if your plants are very overgrown).

It depends on what type of plants you want to grow. A tank full of anubias doesn't need intense light. Limnophila Aromatica on the other hand appreciates bright light. You need to figure out what type of plants you want and go from there. This is a good resource to learn about plant needs:http://www.aquaticplantcentral.com/f...c/plantfinder/

This site also has a plant database but I don't find it as helpful as the one linked above.

I can tell you that dwarf baby tears need high lighting to grow good. and fertilization

Plantbrain has grown HC (dwarf baby tears) with about 40 micromols of PAR, but also with very good CO2. CO2 reduces the plants need for more and more light. Another way of putting it is that with CO2 plants grow much faster whatever the light intensity is.

thats not true... you can look at my HC growing thread... i had a 3 ft florescent single light bulb for 2 ten gallons next to one another and in one of the tank i have HC growing like crazy... the bulb was a 6500k at 30watts total...







co2 is not a problem i have plenty of that to go around but i have a problem with my co2 regulator i hope i wont have to start a new thread over it... well here goes...

i turn my co2 tank on and turn regulator to 40psi... leave it over night and check back again in the morning (11 hr later) and psi drop from 40 psi to 35psi... though it was a leak so i check with soap and water but no leaks that i can tell nor any bubbles from the soapy water... is it normal to get this kinda drop? assuming that in the tank it comes out cold and once out in the regulator it drop due to room temp but i could be wrong any help?


p.s. i turn on to 40 psi then shut off the 5lb tank valve and leave it over night etc
