HC and Flourite in low tech tank?

So I am interested in having HC in a 15g shrimp tank I am planning. No Co2 (thinking about using API's CO2 liquid additive - would love to hear any opinions on this product). Double strip LED light.

So here is my question, will this grow fine with flourite under a sand cap? I wanted to splurge on some ADA Amazonia but would rather save the cost at this moment as I already have a bunch of flourite. I could possibly even get some Eco-Complete if that might be better and still save me some cash.

New to planted tank so the help is appreciated

HC isn't going to carpet without ferts and CO2.

Excel/liquid alternatives aren't always shrimp-friendly and can kill them if you're not careful. Mileage varies on that front.

Eco-Complete is inert. It's basically crushed lava rock.

thanks for the info...guessing I would be better off going with glosso?

I saw a $50 co2 kit in petco - the Ista kit, but read some bad reviews on here and don't really have the money to invest in anything else. Good to know if it would be a waste of time with the HC

Sand doesn't cap over fluorite--sorry. Finer particles will always filter down; generally far faster than you would ever expect.

Also, HC *can* produce a carpet without c02, it just takes a lot of work and patience--more than most people want to put in.

Knotyoureality's right. I tried to cap a flourite / pool filter sand mix with black sand. Now I have a flourite cap over a black / pool filter sand mix. It works well enough...

lol ya, my flourite has mixed a bit with the sand in my 4g tank, the look works in that tank, but I understand what you mean if someone would want a real sand cap
