Yellowing glosso and not-so-lush HC

I think so many people have asked this type of question before. But I still hope that someone can help me with this...!

I am using ADA amazonia, injecting CO2, dosing excel once another day and seachem micro once every week. The yellowing problem with the glosso is not huge but some do yellow from time to time. There is a HC carpet but it isn't as lush as those in other people's tank. Light is on for 8-9 hours. Tried increasing photo period before but it does seem to boost algae growth...

What else do I need? for some reasons, I don't really want to try EI dosing...

Thanks in advance!

Sounds like a lack of nutrients. Try some root tabs i you dont want to dose.

Well to start your not dosing any macros, and posting your water parameters is very benificial.

ph-?
gh-?
nitrate-?

Its hard to say, especially without pictures, that your missing ingredient x. If your using amazonia you should not need root tabs. how old is the amazonia?. Start dosing at the least, kn03 and kh2p04 (nitrates and phosphorus). This is why many encourage e.i , it rules out nutrients as being a 'limiting factor.' so you don't need to guess what your lacking.

IMHO skip the excel, at the very least diy c02 is better and cheaper, without proper c02 concentrations in the water, the plants have trouble utilizing all available nutrients, and are often stunted.

ph is 6.5
nitrate is nearly 0.

And I am injecting CO2 as well. The reason why I use excel is that it does do a good job in checking algae. The amazonia is new (and yea, I don't think that root tab is necessary too!).

You need to dose macros such as nitrate.

The thing is that I am overstocking my tank which makes me think that nitrate release and absorption might be balanced. (The reason for such low nitrate level is quite obviously because of the plants and my filtration system.) On the contrary, you are suggesting that nitrate is too low, right? I am just afraid that dosing extra amount of nitrate might harm the fish and shrimp that I have.

What substrate were you using at the time?

I remember that there was a thread showing what the symptoms are for each type of nutrients deficiency...but I can't find it...

If you really are doing the Nitrate test correctly with all the shaking and its still giving you a 0 result then you need to does some Nitrate. You want to keep it at 5-10 ppm, which wont hurt fish. You should test for phosphate also.

How long has this tank been set up?

I was just using regular pool filter sand. The best substrate ive used for Glosso has been Flourite, it completely filled my 10 Gallon in less than 8 weeks !
