My plants do not seem to be growing at all.
I'm wondering if too much light will actually overload them?

I have 175w of metal halide over 30g.
I can't figure out why I am not getting any growth.

Temp is around 85F.
I dose EI. Pressurized co2.
Any thoughts?

What ppm is your CO2 at? It might very well be the lighting you have over the tank. I know plants like Rotala rotundifolia grow and then kind of bend over if the lighting is too intense.

It is extremely unlikely that you really have 25 ppm if you just measured the tank KH and pH. You need a drop checker, with known KH, otherwise pure water in it if you want to know how much CO2 you really have in the tank.

Either way I am blasting the co2 as I have no fish in the tank. I don't think lack of co2 is a problem.

The bulb is a 10k XM mogul style.

Algae dosn't seem too bad other than all of the glass scraping I have to do.
Initially I had a green water outbreak, no surprise there.

I'll just try and raise the lights to see if that makes a difference.

I seriously doubt it's because of the light unless you have it mounted really high off the tank of you have shaded spots on the outskirts of the tank and that's where you decided to plant.

I have 192w of pc on my 30g, 30-40ppm co2 with lots of fish and double the EI rec. for the tank and I trim about everyweek. But like the others say I have lots of stems that would grow fast under the right conditions, I also have HC spreading like wildfire!

For plants I have,

I'll try and post some pictures soon. Looking for a new camera.
