Hey,

can anyone give me a key indication on how much plants i should put in my new setup.

Heres some plants that ive got atm:

5x 20-30cms Narrow leaf swords
15or so 10-15cm baby swords
1x 30-35cm Maple queen
3x 20cm java ferns

what other plants should i put in...

i was planing to put in some carpet plants...but later on... my first priority is to balance out the plants require so that i wont get hair algae disaster again.

My current tank is basically cover with hair algae on the gravel... and im going to bleach everything out...theres just too much so i'm starting again.

my new setup will have....
1-2mm sand gravel
co2 pressuirize injection
ehiem 2213
120watts of light
3x2x2 tank
