Well, the "low-light" approach generally starts at about .8 watts/USgallon and ranges up to about 2 watts/USgallon, where high-tech approach begins to take over. These two are not the only approaches to planted tanks but they dominate the scene. The problem is that the "watts" are of course not by a long shot a measure of light, but a measure of power. The efficiency of the lighting device and the optical aspects of delivering the light to the leaves are confounders of this simplistic numerical crutch. The guideline was developed for T8 or T12 tubes (I forget which originally) and T5 tubes, being more efficient need a slightly different conversion. Aaron, in his most recent article recommends 1w/gT5 and 1.5w/gT8 for low-light. I assume that since incandescents are less efficient than fluorescents, more wattage is needed to end up at the same place. It might even be that your two 15 watt bulbs, instead of being way too much at 3w/g for a 10g would be about right. But this begs two questions, namely whether I can even hope to remember which volume of tank is now in your pics as you've thoroughly confused me moving tanks to and fro with the neon girl. Am I right its the 10 we've been decorating and its the 5.5 beta one to the right when I see the dual picture? But of course the other question is the more difficult as we must attempt to find some planted tank expert and they've been in short supply lately it has seemed. I suppose you can start a little thread in planted and we'll see if there's any luck. Likewise on the plants themselves. On the face of it they are are of the general types I think are ok but usually the serious planted guys rescue me and give the really specific advice so with them not around as much I'm exposed for the planted newbie that I really am! Still, we could do worse and I can at least say that anubias and vals of all sorts are worth taking a crack at and the others you've mentioned are at least familys I've often seen mentioned as (stem plants in some cases) that are also quite good for beginners to try. As far as prep for nutrition, we over here in the US are at a distinct disadvantage relative to our many UK friends on the forum. They can simply pick up some TPN+ and have a single thing to dose. For us we can either order up some dry chems and mix up our own (I'd have to really dig to find my link for the chems) or we can dose liquids. My choice so far has been to dose liquids - I use Seachem ferts in a great variety of bottles. That has come about as my way of "stalling" while I slowly gather info with which to get more serious at some point hopefully. The simple Seachem Flourish (the plain one), along with Excel is a reasonable way to start I feel. WD
So now about the lighting and fertilizer?
