Thanks!
With an eclipse system, take out the biowheel filter otherwise it'll waste all the co2. If you want to grow the nice stem plants, you'll need to replace the lights that came with it with PC's. There is a way to do it on the web, but i'm not sure if it'll allow you to keep the integrated filter. Get a canister filter, they are way better anyway. I think the zoo-med 501 is like 30 bucks online.
Get shultz profile from homedepot. $6 for 10 pounds! It has little nutrients but has a great CEC quality (means that it absorbs nutrients and releases them as the plants need them). You can use Jobes Sticks like me, just don't stir them up.
What you can do, if you have a small enough tank to make it economical, and can remember to dose daily, you can dose Flourish Excell everyday instead of co2. It's a liquid carbon source. It's auctually an isomer of glutaraldehyde, which is used to sterilize surgical and dental instruments. You can probably get some from your job, as it's not a controlled substance. It's also part of Embalming Fluid. Yummy.... Seriously it can make you drowsy and dizzy and burn your nose and skin so don't smell it or spill, and that includes smelling Seachem Flourish.
If you get a breakout of some specific algaes (like black beard algae, IIRC), go can overdose excell for a few days and it'll kill the algae and boost your plants. Overdose the daily dose 3x , not the initial dose.
