Okay so this is my first planted tank and after seeing tons of beautiful pictures and videos I wanted to try my own. So far I have succeeded in growing squat. Is it my lighting? Is it a co2 issue? I'm on a budget and I'm trying to get the biggest bang for my buck. I was planning on buying a pressurized co2 system but I'm not sure if that's my biggest problem...

I have:
-75 gallon tank
- fluorite substrate 3 inches deep (I also poured black sand on top of that for looks but am not sure if that matters much)
-Aqueon t5 Dual Lamp fixture (48 inches) came with 6700K daylight bulb and Colormax bulb
-Marineland 36 inch LED light bar (came with the tank)

And I have been using Flourish Excel for about a week and haven't noticed a difference :( and from my novice eye I haven't even seen any algae...........

I'm about the point of getting frustrated..... someone help me lol

Thank you, Andrew

What plants are you trying to grow?
Right now I am trying to grow amazon swords, java fern, and Dwarf hair grass, which are the plants I managed to find at petsmart. Eventually I would love to grow dwarf baby tears but from what I've read co2 is mandatory for that.

Edit: I tried doing DIY co2 and bought a beautiful spiral glass diffuser however I don't think the setup I had generated enough pressure to actually push the co2 through my diffuser :(

How many watts is the fixture? Seems you may need to do 2x of the 6500k and ditch the color max. One 6500k is pretty low. I doubt the LED bar does much of anything for the plants. Also, DHG is pretty tough to grow w/o CO2. The java fern should grow, but its a slower grower then the swords.

Also fertz? are you doing some comprehensive and K+?

And you have any pictures? Are they yellow? holes in them? Any kind of deficiencys?

I'm working on pictures but I'm just as awful with computers as I am growing plants apparently. the lights are 2- 28 watts. Would just adding the one 6500K be enough? And my plants turn yellow and get holes.
All I've added is the flourish excel.

well definately going to need some fertz. SOme good starters are Flourish Comperehensive and potassium. Look in the "water parameters/fertizer" thread sticky for more types of dosing regimes. Yellow leaves and holes are usually caused by low potassium and/or low nitrates.

Also 1 28 watt 6500k bulb over 75 gallons is not near enough light. I would expect your javas to grow decent on 2 of them and maybe your swords. But cant be positive

So your Javas are doing ok. Make sure you unbury them, those are rhizomes and not roots. You can tie them with thread to a log or rock, but need to have access to the water column.

Im not as experienced with swords, but they really seem to like CO2 injection but could possibly get by with fertz, more light, higher dose of excel and mebbe some N,P,K tabs (search osmocote + on this forum easy to make or purchase). I would say 4-5 cap ful of excel daily (gradually increasing) as well and you should be able to get them growing. Someone else may have more experience and have a better idea.

Id recommend plants like Crypts, Bacopa, Camboba, hygrophila angustifolia, and other "low tech" plants (see low tech forum)

The Java in pic 2 should be tied off and not buried under sediment? I did not know that! and I will give those things a try. Thank you very much!!!

This is almost certainly a lack of lighting (or possibly plants recently added and damaged during shipping). Look at the number of dead sword plant leaves. Compare that to the health of the low light tolerant plants like java and anubias.

Speaking of anubias, what happened to the skeletonized anubias plant? Do you have a pleco in the tank or something else that eats plants?

For a 75g tank I'd recommend you put at least 110 watts of power compact or T5 HO on it to reach medium lighting conditions.

The dead swords are the latest batch of dead ones. I already trimmed the first dead swords that after I planted and gave it a few days. I have new leaves forming that are bright green but start to fade after a while.

I have a pleco, a small black one with gold dots however it usually hides under my drift wood and I've never actually seen it go near the plants. I have 2 angel fish which I think might nibble but from what I've seen with the other leaves (prior to trimming) they just slowly got yellow, then got holes and the holes spread until current state.

As for lights my plan was to swap out that color bulb for another 6500k, and eventually add 2 dual 24inch lights. One on each side of my tank.

Plecos are mostly nocturnal so you wouldn't see it damaging the plants unless you turned the lights on half way through the night and caught it in the act.

So to clarify what you said. The swords in the photo above are newly added and the leaves died shortly after adding them to the tank?

A second problem exists where the swords put out new leaves and these very newest leaves turn yellow and die?

Can you get a close up photo of the new yellow sword leaves? It makes a difference if the leaves are new or are older leaves.
