will this 120 g setup be alright ?

[youdontknowme]

4 ft x 2ft x 2ft.

no co2

lighting fixture : 4x54W ( highly polished individual parabolic reflector for every single bulb but will only be switching on 2 bulb )

light bulb : D&D giesemann powerchrome aquaflora 54w & D&D giesemann midday 54W

filter : 2 canister filter total ( 2300L/hour)

substrate : 45 litre of ADA new amazonia

stock : 16 cardinal , 6 rummy , 6 cories , 6 discus

-carpeting dwarf hairgrass , amazon swords , ( still thinking of what to add )

Not sure how well the DHG will do without CO2; I have always thought of it as a CO2 required plant. Maybe someone more knowledgable than me will chime in.

Otherwise I like it. If it were me though, I would choose either 22 of the cardinals or rummys and not some of each; one larger school looks better to me. Personal preference.


What kind of discus you looking at?

thanks for the suggestions. i would go for cardinals then. (most probably )
i already have discuses ( red map , LSS , golden albino , and a tiger checkerboard ) . just going to transfer them over as im upgrading my tank from 50gallon to 120 gallon .

now , do anybody know if DHG require co2 ?

I have seen mixed results reported on DHG, but I think it's possible. Low-growing crypts such as parva, willisi, and lucens (and hybrids thereof) work great with no c02 as a different option if you have the patience to let them grow out.

i see... any other alternative if were to carpet plants without co2 ?

[tomfromstlouis]

Don't forget to factor in temperature; most discus are kept at higher temps that restrict plant choices as much as or more than CO2 or not. At what temp do you keep yours?

Temperature is not a problem since im in asia, our temperature ranging from 26-30 and 28degree celcius in room temperature . In my 55gallon planted discus, the plants and discus are doing well but im using diy co2 and diy co2 is useless when i use it on 120gallon .

bumps.

anyone here can suggest what carpet plant ?

[discuspaul]

Carpet plantings will not likely do very well in the 2 bulb lighting you plan on (and without CO2), but more importantly, the use of carpet plants will probably significantly limit your ability to maintain a very clean substrate environment for your discus.

If you use pressurized CO2, that could also complicate keeping discus with the daily swings in pH that could occur. That's my .02

I would avoid doing any carpet planting in a discus tank - just keep things simple for best success.
