there's so much to learn... both of ya'll are so helpful and full of info, thanks!
i loved my biology and botany classes so im one of those people that actually finds this stuff more on the side of being really interesting rather than scary and boring, so im up for learning about this stuff! the key thing to remember with me working on my planted tanks is im on a budget for right now (college student). so don't be discouraged from telling me about the more expensive stuff like CO2 systems, its just that i might not save up the miscellaneous money to buy it for a while. this tank setup that i have at the moment would cost hundreds of dollars if not over a thousand to replace it right now, but i didnt put it together overnight, i put it together over a period of years. and in another year i just might add something like a CO2 system, so just keep that in mind.
so... im taking the 29 gallon and making it a long term project tank! yay! i should probably make a new thread about it... a "journal". yep, i think that's what ill do, but im gona think about what direction im going to take it in before i do that. until then... lets get back to what this thread is about.
okay so the reason it has been suggested that i remove one of the bulbs in that fixture is because the extra output from running both at the same time stimulates the growth of algae?... and that's true because... the plants that i have at the moment only use up so much light in the process of photosynthesis in combination with using up, simultaneously, vital nutrients in the water column and sand in an effort to convert those nutrients into usable sugars that are used by the plants other cells to sustain a healthy life? ... and with that high level of light combined with the particular level of nutrients in the tank, there happens to be enough extra, of both, to also sustain the growth of algae in addition to plant growth. so in order to prevent algae growth i need to either reduce the level of light or reduce the level of nutrients, and since im not using ferts (at the moment, you guys are kinda convincing me to start doing stuff like that though) the only other option is to reduce the level of lighting. is that right? and before you answer that leads me to the next question... if that is correct, couldn't i fix the algae problem by also adding more plants?... in doing so lower the level of nutrients?
so my options for getting rid of algae are:
add more plants to use up the extra nutrients in the water column and starve the algae.
remove a bulb to prevent algae from performing photosynthesis at a high enough level to grow.
correct?
