Are you dosing anything now?

I think you would be fine with dosing setup. You may want to consider Seachem equilibrium instead of the flourish.

Seachem equilibrium is not a fertilizer supplement, it's a buffer to help reconstitute or increase the pH of RO or acidic water.

Will you be running CO2 on this tank? I suspect you're really going to have to limit your photoperiod with T5HO lighting if not. Or add floating plants to help with light control.

Check out the stickies at the top of the water parameters forum for advice on putting together a balanced fert regimen.

i wasent planing on using co2 untill maybe later on. you think 108 watts of t5 is too much for low tech 75 gallon set up??? the only thing i have dosed right now was seachem flourish. will the plants be ok for atleasts a 2 weeks or soo till i can get some dry ferts ??? If i added c02 to a 108watt t5ho set would i have to dose alot more and would growth be really good?

You have a nice looking selection of plants. I am looking forward to seeing this tank develop as you get everything arranged in there.

What are your plans for fish?

Im gonna be putting a few diffrent rainbow fish in the tank. I have a few now but there in my 26 gallon tank. I still need to buy more plants =) haha. The plants on the right front side of the tank are amazon swords that i cut way down. I dunno if they should be cut down more or what. They were dieing in my 26 gallon tank becuase i just have gravel and dident use any ferts and low low light soo i cut them down and maybe they mite grow back lol dunno welll see.

With that amount of light and no co2 you will have a serious algae problem in the near future. About dosing and co2, it depends what you'll use as a substrate and what are you trying to grow. I recommend typing "mineralized topsoil" :EI dosing" and "PPS dosing" into the search bar in our forum, you'll find a lot of useful info.
By the way, I wonder when they'll stop using wpg (watts per gallon) measuring in those articles in fish magazines and books. I picked up a recent TFH issue and they still trying to persuade that 2wpg is a low-light setup, no matter what bulb type you use. It's just not true anymore as T5's are very efficient light and my opinion is 1.5 wpg for T5 is nothing but a high-lighted tank. Who's with me?

I run 108 watts of T5HO over my own low tech 90gal and am having algae issues ever since I removed my floating plants.

T5HO is extremely powerful lighting.

Another option to moderate the lighting is to raise the fixture further off the tank.

Glass tops will cut down light some (depending on how clean they are LOL), but that's still a lot of light.

The brown on your Anubias is probably Brown (diatomacious) algae; will it rub off if you rub your finger along the leaf?

Yes, Excel would probably help till you can get a CO2 setup.

Going back to look at the photos, I also can't see the rhizome on your Anubias. The rhizome must be up out of the substrate and exposed to light or it will die (and the leaves with it).

You might try adding some floating plants to help with light control, too.
