Hello

So, I have a 29 galon aquarium with a lot of plants in it. Lots of types( amazon swords, anubias, alternanthera, limnobium, java fern, ludwigia, saggitaria, hygrophila). The aquarium is 2 months old. First 2 weeks I did a proper fishless cycle. Now I have 2 gouramis, some corys, some barbs, some galaxy rabora, 4 snails and a few ghost shrimps.
As equipment I have a LED light + a T8, Eheim 2215 filter + hydor koralia nano 425 for water circulation + pressurised CO2.
My questions :
1. All plants grow quite well, expecially the hygrophila and the amazon swords(the rubin types is awesome). All except the dwarf hair grass. That one refuses to grow. Absolutely no progress since day 1. Have no ideea why.
2. Most small plants appear to have some dust on leaves. I read that in fact it's diatoms. Constantly I feel the need to shake them a little to get the dust off. How can I get rid of it?
My water parameters:
pH: 7
kH: 7
NO2: 0
NO3: around 10-15
PO4: around 1

I dose using the EI method but here comes question 3:
3. If I see that on the day I should add macro the PO4 is 1 and the NO3 is 15. Should I still add those?
And the last question I promise:
4. If I try to increase the CO2 levels then the fish will have trouble breathing and will stay at the surface. Does this mean I have enough CO2?

Thanks a lot!

This is the only part I can answer for you...I'm pretty sure if your fish are gasping at the surface, then there is too much dissolved CO2 in the water

Hopefully someone can answer your other questions for you

Yes, definitely too much CO2 if your fish are gasping, do you have CO2 indicators in your tank to tell you? This is what I have and it works very well:

There are other "stylish" glass ones too, but this one does the job. Have to be careful with CO2, I killed a bunch of fish not knowing what the CO2 levels were, if I would have had this indicator I would have seen the yellow indicating too much CO2. Now I have an air pump running at night to increase the O2 levels at night by adding surface agitation.

I don't use the EI method, just weekly Seachem Flourish, iron, potassium and phosphorous as needed, along with pressurized CO2.

The diatoms are caused by silica/silicate in your tank, http://www.aquascapingworld.com/algaepedia/full_view_algae.php?item_id=79

Here's an overall guide to algae; http://mininaturecube.blogspot.com/2013/07/algae-guide.html

I had a small diatom issue, but issues with hair and filamentous algae and I increased circulation in my tank which decreased it a lot, I also manually removed a bunch and spot treated with hydrogen peroxide, and upped to dosing excel every second day. Then was reading about a miraculous little fish, Otocinclus that Mr. Slap (as well as some other AC members)has in his tank. Got 10 for my tank (cause that all they had at the LFS) and they have done wonders for my tank's algae issues. I tried nerite snails before and they started out well but algae continued to the point where my background was more green than the grey/brown and terracotta. Since I got the otos I can see the background again.

Bonus is they are cute little guys...

Thanks! I will add more surface circulation. However I cannot add more fish since I am already fully stocked. This answers my questions 2 and 4. Any ideas about 1 and 3?

Can't help you with #3, I don't fertilize with dry ferts.

However when I tried hair grass it never took off for me. On the other hand in the 5 gallon betta tank I have upstairs it is doing well-I think light intensity has a key because the light is a lot closer to the plant in the 5 gallon than the 55 when I tried it. Just a guess though.
