If I have a Finnex FugeRay on a 29, will I have high enough light to need CO2?

No It does not, I have 30" fugeray on my 29 as well. It ends up being lower medium lighting. I do dose excel, and am working on getting DIY CO2 for better plant growth.

I've linked the Par data for the fixture

Thanks. I'm going to be dosing Excel. Will it be able to grow rotala species like indica and wallichi well?

If I get a Ray 2, will I need CO2? Can both of them be mounted on a regular rimmed tank?

The RayII will probably give you medium light, and CO2 will be necessary to avoid lots of algae problems. But, you wouldn't need to use such a high bubble rate as to worry about killing your fish.

I don't think I'm going to get a Ray II. I've already tried DIY CO2 and it didn't work for me. Also, I doubt my dad would want to spend $200 on a pressurized CO2 system. I'm trying to avoid all of the algae so that's why I'm going to downgrade to a FugeRay. It should put me at low-medium correct? Will it be enough to grow rotala species like indica and wallichii well?

You might be able to use Excel as a carbon source for the plants, and grow those plants with the FugeRay. They will grow slowly compared to what they do with more light and CO2, and they will tend to just be green plants, without red or yellow colors on the leaves.

Thanks Hoppy!

Will I still need to dose EI? Should I change my dosing regime?

 

[QQQUUUUAADDD]

Anybody?

Plants require nutrients to grow. The more light and CO2 you add, the more nutrients they need. A low light tank will still use nutrients, but a rich substrate or reasonable fish load with associated feeding can sometimes sustain plant needs. A low light version of EI can be applied very easily, give your plants the nutrients they need and not go overboard. You will be able to modify the whatever dosing you do by measuring phosphates and nitrates. If you have excess nitrates and phosphates after your waterchanges, reduce dosing.

Try the calc below. It has a low light dosage option.

I'm pretty sure it's low light correct? Any easy way to convert grams to teaspoons?

 

[TexasCichlid]

A digital scale can measure out the grams. I use these as well.
