what kind of DIY Co2?
it should be fine
maybe you could grow out some anubias nanas or anubias nana petites on a piece of DW
if its a plant only tank.........i'd make sure there is plenty of ferts(which you have), Co2(which you also have), and good substrate...........maybe eco-complete? a bag is $15 at petco..........online
or maybe just pool filter sand at $3 for a 10G if they have 20lb bags
maybe you want to keep a few shrimp? well, they'd help with a few things, keep the water better, and a side breeding profit maker
various cheap plants which you can find at petco for under $4 each
amazon swords
crypts
rotalas
grass(they have weird ones that are doing well in my tanks
)
anubias
DBT
etc.
and other p[lants you may want
jungle vals
THESE GROW LIKE CRAZY!!!
I had 5 in my 72G with 4X54 T5 HO AND NO CO2(LOTS OF ALGAE
)
But in 6 months i had over 200 and sold like 1/2 of them for $100
