i can't afford the pressurized system right now, but I do appreciate the info. As an update for anyone that cares, it has been 3 days since i started with one 2L and it is the 2nd day w/2x2L diy co2 and my version of Dr. Jay's diy reactor using a 1L soda bottle and a 90gph pacific hydrostar mini submersible fountian pump from Harbour Freight Tools($7). i cut the bottom off the bottle then cut slots out between the "legs" of the bottle using a soldering iron then put a hole in each leg, next i put in a sponge and slid the bottom back over the other part of the bottle. i took an old air stone and crushed it to use the stem, which i cleaned off and put a small piece of tubing on and put through the bottle near the neck and attached an airstone to it inside(of course before i put the bottom back on). the pump is connected with a 1/2" nylon elbow through the cap. so anyway, back to the update my plants are looking better and i am seeing some pearling like a bubble here a bubble there, but i dont think(am i wrong?) that i should expect much more than that with low light even if i up'd the co2. oh and i tried finding greenleaf and im not sure it has a walk-in store maybe its just online? maybe someone could help me out here. i did however, get a red sea drop checker i will momentarily be setting up and i'll post the results later.
Thanks in advance to anyone who cares and/or can help
