My new 80 gallon

I'm setting up my new 80 gallon planted tank right now. It had a leak so I had to Re-silicon it which was a bummer. I want to make a big order from sweet aquatics but I dont know what to get. I was wondering of any of you would have a stocking list suggestions. I don't care about it being a biotope either. Thanks

before you go to sweetaquatics( amazing store by the way).....

what type of lighting do you plan on using? some plants do well in some light, while other require special lighting, do you plan on using any CO2??

Alot of us on here do not use high-tech lighting or any CO2. for some good reading, I really suggest reading Byron's four part series about a low-tech approach to a thriving planted tank.

As byron will be along to tell you, a planted tank "does not need to be expensive, nor high-tech"

lighting is a single 6500K 36" T8 30 or 40 watt not sure which one to get. No CO2 to start out. I may do it later down the road. I have already read byrons guide its really good.

A 36-inch tube (which would be max 30w, not that that matters a lot) over an 80g is probably not sufficient for plants, but I'm wondering about the tank dimensions? Is this a standard 4-foot long tank, or something else (like a tall cube)?

Its a 4ft tank and its 2 feet tall. The ballast says that it is for 1 30watt-40watt bulb. I could cut it and extend the wires to make it a 48" fixture. Do you think that would be enough?

I'm thinking with a two foot tall tank, you'll need more than you're single 36" 30W tube. I have two 48" tubes over my 55G. I'm thinking you'll either need a longer (to cover all 48" of your tank across) or stronger (to get down to the bottom of a 2 foot tank)

I'll let Byron or someone else get to the specifics of the light....

That's identical to my 90g (90 USg is probably the same as imperial 80g, doesn't matter, close enough).

First thought is that the tube should extend full length (4 feet), or alternatively two tubes end to end, but a 48-inch tube is preferable because they are more widely available in different types and easier to manage, and you will get consistent light full length which will not be possible with two smaller tubes.

A single tube over a 80g is really pushing one's luck; I have had this over a 55g 4-foot, but that is narrower and shallower, and it just cut it. I have two 48-inch tubes over my 70g and 90g and I would recommend two 48-inch tubes.

Now here you have two options; regular T8 tubes, two of them, work well (that's what I have). Alternatively, a single T5 tube would work, in Ho (High Output) a T5 is approximately equivalent to two T8 tubes, with the same "type" of tube [full spectrum, 6500K, etc]. Of these two, my preference is for T8, because then you can combine two different tubes for good light and nice appearance. If you've looked at the photos under my "Aquariums" below my name on the left, I have a full spectrum 6700K tube and a cool white-type tube on each tank; this give excellent plant light, plus a "cool" look which I personally favour because it depends the blues on the fish a bit but not excessively, it makes the plant greens looking stunning, and it has a "subdued" feel to it which creates the sort of environment the fish prefer.

Thanks Byron. Do the 48" shop lights at home depot come with a 6500K or 6700K bulb. It seems like that would be the best way to go. I've heard that they are only $10 a pice. So, on all of your tanks you have a 6500K bulb and a 6700K bulb. I don't now anything about "cool white".

By "shop lights" I assume you mean the fixture; I don't know if tubes come with them, but if they do I suspect they are basic (=bad) for our purposes. But tubes are not expensive, HD and similar hardware stores carry a line of tubes by Phillips, Sylvania or GE,or all three, and each makes a 6500K "daylight" tube which works fine. The "cool white" is slightly more in the blue, and plants respond best to a mix of full spectrum (the daylight 6500K) and cool white. But two daylight would work fine. It really depends upon you preference; full spectrum provides what the plants need and colours appear natural to us; adding cool white "cools" the appearance a tad (toward the blue but not that much that it becomes ghostly), while adding a warm white "warms" the appearance (more red/yellow). The advantage of buying tubes at HD is you can try them over your tank for a day or so and take them back if you don't like them.

I like the appearance of full spectrum and cool white; on the large tanks with dual tubes, one is a 6700K full spectrum (on all three) and the other tube is a 11,000K (on the 115g), a 10,000K on the 90g, and a 6500K on the 70g. The latter tank looks just a tad more warm or yellow than the others because of the second tube. The higher the K number, the cooler, the lower, the warmer--generally speaking; different manufacturers can also adjust the colour with phosphors so the Kelvin is not always accurate but it does indicate the "leaning" of the colour.

Thank you. I bought some quickqrete gravel from HD for my tank. It say that you can use it for fish ponds. I think that it might be non-inert. I checked the pH of the source water and then I checked the pH of the tank water with the gravel in it and it was higher. I did add a de-chlorinator to the tank water. Do you think that could effect it?
