I have a heavily planted 55 gallon tank (Val, crypts, rotallia, several small swords) with dozen cardinal tetras, 5 rummynose tetras, 5 emperor tetras, two pearl gouramis, 6 Corydoras sterbai and five juv angelfish. My tank is lit with two 110 watt (VHO/Icecap) bulbs.
The tank has been running in this configuration for about a year and a half. I've had extremely good growth w/o CO2 (I need to pull vals every other week, crypts are multiplying, though the Rotallia isn't as bushy as I'd like).
I have a CO2 Reactor I purchased on Aquabid that is a PVC drum (6 inch diameter) with an airline valve on the top. It's about 10 inches high, and I fill it with 2 cups of sugar and another 5-6 cups water.
I have had this hooked up to a small powerhead in the past, but haven't used it for about 6 months.
1) How will adding a Power Reactor (from Plantguild) help? Is it incrementaly better than the small powerhead?
2) Someone suggested that I have 2 yeast reactors feeding the tank, mostly so I don't have to worry about production drop off (staggard maintenance/refill schedules). Is one PVC reactor enough, or should I think about adding another?
3) If I add a second yeast reactor, can I hook it up to the same power reactor/defussior?
4) Do I need to worry about CO2 production at night? It is too impractical to shut off CO2 manually every night.
5) Any other suggestions for get the most out of a DYI setup for my 55? (other equipment or configuration)
