welcome back dekstr... great tank for the low maintenance you describe. how much light do you have over it?
i'm going med. light over my new tank because i want to cut down on the maintenance too. gonna select slow growing plants and/or minimal maintenance plants to make things easy.
Again, good to have you back. hope your non planted tank business went smoothly!
For lighting, I have:
two 55w compact fluorescent bulbs, 5500k (the DIY kit from ahsupply.com)
two 28w coralife t5 normal output fluorescent, 6700k
55+55+28+28 makes 166 watts, but probably less than that in real life as I have a glass cover over the tank and the bulbs are more than 1 year old.
I slowly turned down my c02 from 1-2 bubble per second to about just under 1 bubble per second. My drop checker never really worked and I never really tested pH / KH. The photoperiod is about 9 hours a day, the solenoid to the c02 is attached the lighting timer. I haven't tampered with any of the (light amount, photoperiod, fertilizer dosage, water change schedule, water temp, c02 amount) settings for about half a year now, other than to tweak the c02 levels because of the regulator goes slightly off every once in a while.
I have coffee anubias, java fern and that big crypt plant as the slow growers. I just pulled out the crypt plant yesterday, selling it off because it's too large for my tank.
The frogbit and duckweed take over the tank every 3 weeks, and it really dims the light once it covers the entire surface.
I started off with 3-4 leaves of java fern 1 year ago, and now I probably have about 6 to 8 separate plants. I gave away about three or four massive java fern bunches already too.
With c02, the growth is tremendous even at lower levels compared to when I had no c02.
I will say that most plants adjust well to almost any conditions, from high to low light if you give them time to adjust and keep every factor very stable.
Good luck on your tank, looking forward to it.
As for non-planted tank business, just swamped with school and work and volunteer and extra-curriculars, so the planted tank business has taken a backseat...
but I hope it'll pick up after Christmas when I go on my 8 month office internship.
