first question is lighting. i know this asked alot but im looking for any opinions on whether to get a 4 or 6 bulb t5 fixture. ive seen a lot of threads that have 4 bulbs and seem to be able to keep almost anything they want. 6 bulbs would definitely let me have anything i want but i think it might be overkill and i dont want to have to hide every lps or softie that i get. however, i also want to be able to keep any sps in the top half and have great colors. i also want the option of getting a clam sometime down the road. so the question is, will a 4 bulb (probably tek light fixture) let me do this?
second question is flow. if i have a false wall, what pumps will get flow from one end to the other ( ~31" away )? i was thinking of having two controllable koralia 2 or 3s with one on each side of the main rock pile pointing lengthwise. will this get enough flow all the way to the other end? if i have a false wall i could also have a return pump with some locline spitting flow out a little farther down but i dont want to have locline extending through my tank either. other option is a vortech on one end but i feel like that will eliminate my idea of having a centered large rock pile and would make the idea of a false wall pretty much dead.
so thats my preliminary plan and any opinions or suggestions are welcome but i do not want to drill this tank or have a sump. thats why i like the AIO option so i can hide the heater and have a space to put some chaeto in there for nutrient export. ill try to take a picture of my empty tank with some props in it to give you guys a little better idea of the layout im envisioning.
