I setup a Spec V a couple months ago. I upgraded the light to a Fugeray 16", which fits on the Spec's lid perfectly.
Other specs of the tank - organic potting soil capped with Fluval Shrimp Stratum. Light Flourish Excel dosing. Was dosing Leaf Zone until I started getting green hair algae, which was probably responding to the iron in the supplement, so I stopped that. Tank has 4 large Moscow guppies (babies at any moment) and 2 Amano Shrimp. Hitchhiker ramshorn snail that I kept because he looks cool. I also have a Mopani wood "branch" at about a 45 degree angle in the tank, making a nice arch for fish to swim under.
Here's the plants I have in it and my experiences with them so far with this particular setup:
Responded well to the light, growing about 3/4 of the height of the tank in 3-4 weeks. With the brightness of the Fugeray, the leaves grew densely together at the plant's top, getting longer and narrower than what you typically see pictured. However, this density shaded the leaves closer to the bottom the stem, causing them to all fall off. Plant this sort of behind something to hide the bare bottoms.
Similar to the Luwidgia, this grew almost to the top of the water, getting much denser at the top. Also turned a lighter shade of green. The bottom leaves didn't die, but instead side-shoots formed, a couple growing horizontal along the substrate about 5-6 inches. They started blocking light of other plants, so I pulled the whole thing, as it was intended as a "place-holder" until the Luwidgia took off anyway. Didn't expect the huge root mass that had developed already! Messy.
Originally meant as a floating water-column nutrient soak, I ended up cramming several stalks into the substrate, and then it really took off. Leaving aerial roots that eventually grow into the soil. Keep trimming main stems right above any side shoots, and it's gotten nice and bushy, jungle-y even. Should make a nice place for guppy fry to hide. Planted along the back glass to hide outlet/cords behind the tank. Also, this form of Anacharis is not susceptible to melting from Excel.
It's gotten a couple of leaves since I put it in the tank, and hasn't lost any, so it's doing well. Slow growing as is typical for this plant, especially since it's in the shadow of the Mopani wood.
Crypt Wendtii (Florida Sunset)
: Split this in two when I got it, planted in diagonally opposite corners of the tank. No crypt melt at all. Larger one tripled number of leaves and height in just over a month; smaller, more shaded one doubled its leaves. Even planted two pieces of the rhizome that broke off when I took it out of the original pot, jammed them in the substrate, and both pieces sprouted leaves already.
Had two pieces of this, less than half an inch in size, that hitchhiked on another plant. Stuck them in not really knowing what they were, but thought they might make good foreground plants. Now I wish I put them further back, as the largest has leaves 4-5 inches in length. Both have sent out runners with daughter plants popping up already.
This was attached to the Mopani wood when I transferred it from another tank. The wood is easily removed from the tank so I can trim the moss back when needed (done once already). Would only recommend this moss if you can do the same, or don't care about it taking over a portion of the tank. It can also get messy looking as it easily catches crap floating around in the tank.
You'd think with all those plants my tank would be a jungle, but it's still a little sparse for my liking (especially after I pulled the Wisteria out). But now I'm ready to sit back and let things just fill out on their own over the next few weeks to months.
As a foreground suggestion, I managed to get ahold of some narrow-leaf micro-sword for another tank, and its doing pretty well. Seems a bit easier to care for than regular micro-sword.
Hope any of that was helpful
