CO2 needed for a low-light tank?
Hello all,
I've recently renovated my low-light tank (27 gallons
nominally, 30 W fluorescent lighting). That is, I've removed
all the plastic plants, 'enriched' (with Profile) the
substrate and increased its depth, and added lots of real
plants.
Assuming I keep the various other plant nutrients in the
proper range, will injecting CO2 benefit the plants in this
tank, or is it too 'slow' a tank to derive much benefit from
CO2 injection?
The plants in the tank are
- java fern
- 'christmas' moss (thanks again Mr. Loh!)
- mexican oak leaf
- a variety of crypts
- two different anubias species
- bolbitis fern
- two different types of swords (E. Bleheri and
E.Peruensis, I think)
- Bacopa caroliniana
- Hydrocotyle sp. (leucocephala, I think)
- Hygrosperma corymbosa 'compact'
- Saggitaria subullata
Water from the tap has
- total hardness as CaCO3 140-175 mg/L (=ppm)
- total alkalinity as CaCO3 106-127 mg/L
- calcium 36-48 mg/L
- magnesium 12-13 mg/L
- potassium 0.51-0.64 mg/L
- phosphorus <2 ug/L
- sulphate 35-44 mg/L
I have a pretty high fish load in the tank currently. All
the fish seem happy with all the new plants though.
Thanks for your advice,
T. =8)
