I will take some pictures of my current DIY CO2 systems, i am only using them on my 10 gallon tanks right now. Going to be using one on on my 75 also until i can afford a pressurized system lol

Hi and welcome to Tropical Fish Keeping forum.

Reading through this thread, I spotted mention of a 4-tube T5 light system, presumably for your planned 75g discus tank. I myself would not use that much light over discus, it will severely stress them. Just an observation, I can go into more if you ask.

Thanks for the info! I was going off the 3-4 watts per gallon rule of thumb I have been hearing. Send me a PM if you could with the info please :)

Thank you very much. I support myself too, since I was 17. And I'm majoring in biochemistry with a focus in molecular and cellular biology. I would really like to do a research project on the infamous angelfish AIDS virus. Most people haven't heard of it but if you google it you'll see :)

Here is the first picture of my 75 gallon before it is transformed into the beautiful planted tank. It is running with the fish i have now.

Fish:
4 blue gourami
5 white angelfish
7 zebra danio
1 chinese algae eater
2 cory cat
10 neon tetra
1 bala shark

Equipment:
-two 55 gallon HOB's (one on each end)
-UV sterilizer
-Single bulb light (new light next week)
-Heater

Running at 80 degrees fahrenheit. With a few plants and a mound of driftwood (the lighter piece is fake but i like the look of it mixed in to the dark brown wood.. kinda like a new tree's roots are taking hold and also i have some anubias tied to the real wood right now. Once its roots grow in they will start draping down all the other wood and look reallly cool)

This is how its gonna be until i set up all the other things (plant substrate, lighting, PLANTS *obviously*, DIY CO2, getting rid of some fish to make room for the new stock, etc.)

I'll comment in the thread, others may be interested, though long-standing members have seen all this before.

First on the light required for plants. The watts per gallon guide works if one is considering regular T8 tubes or T5 NO (normal output, as opposed to high output or HO) tubes, and over largish tanks (>50g). It will not work with T5 HO which is significantly brighter (more intense) light. Watts is only the measure of energy used to produce the light, not a measure of light intensity which is the important factor; while most 48-inch tubes are 40w, some manufacturers make tubes requiring less energy/electricity with the same light output, example ZooMed's 48-inch tubes at 32 watts that are equivalent in output to 40w tubes of the same spectrum.

Within this guide, the number of watts depends upon the setup; with no added CO2, in what I refer to as natural (low-tech) tanks, 1 watt per gallon is more than enough. The photos of all my aquaria ["Aquariums" under my name on the left] demonstrate this; I have less than 1 wpg on all those tanks, except for the 70g which has 80w. I noticed your mention of CO2, so that requires additional light and other nutrients to balance.

But at this point I would consider the fish. Discus come from dimly-lit waters. As indeed do most of the SA and SE Asian soft water fish; forest streams, flooded forest, pools, etc. that are overshadowed by dense forest canopy and receive very little if any direct sunlight--one reason many of the streams have no plants. The fish become stressed under bright lighting. Providing the minimum amount of light required for the plants is a good goal; and always using floating plants to further shade the light. I am several other members have experience with fish becoming more colourful and out and about much more when light was reduced; and this is no surprise, since it is their natural instinct.

Last year I had to replace one of my old T8 fixtures, so I tried a dual tube T5 HO. It was over my 5-foot 115g tank for a week before I took it back and got a regular T8 dual-tube fixture. The T5 HO was simply too much light; I comically thought the poor fish would be asking me for sunglasses. I have 80w of full spectrum (two 48-inch tubes) over that tank, and it is more than sufficient as the state of the plants in the photos demonstrate. And the fish are relaxed.

Thanks for the info!

saved me time from figuring out that the lighting would be too intense once i plugged it in lol Ill still get the 4 bulb t5 with moonlight LED's cause im getting it from a distributor for an insanely good deal, so i will only run a couple of the lights so it wont be so bright, also do you happen to know the best spectrum of lighting for discus planted tanks? I assume i will have to do more research on the plants themselves to figure out my lighting spectrum for the best growth and how i want them to grow. Or would you recommend a simple full spectrum bulb?

I do admit i do not want to make a tank the exactly mimic the darker/cloudy natural habitat they normally live in, because i want to be able to view their beauty instead of seeing a dark figure swim by lol so my tank will definitely be brighter than their normal habitat, i will just have to find a good balance of my lighting to keep them bright but not stressed.

The (minimum) light I have is quite bright, and I have no trouble seeing the fish. On all this, have a read of the 4-part series stickied at the head of the Aquarium Plants section entitled "A Basic Approach to the Natural Planted Aquarium." Such a setup is ideal for discus, or any other forest fish for that matter.
