The pH of the 150 is kept at 6.4 with pressurized CO2
. It goes down to 6.0 overnight as the plants outgas CO2
when not photosynthesizing, but the CO2
controller does not turn on the gas until the pH reads higher than 6.4. It does not take very long once the lights turn on for the CO2
in the tank to be consumed by the plants, and the pH begins to rise.
I'll not give specifics as to what I paid for the fish, but they were not cheap fish by any means. The angels were priced at what I'd consider a good deal on discus (they are just about the same as discus in terms of their care and requirements). All I can say about the catfish is that it was ridiculously
expensive. 8O It's the kind of fish that you have to feel very confident that you are able to meet its needs, lol.
The catfish right now is obsessed with Hikari sinking wafers, or really any sinking pellet. I generally feed him with forceps to be sure of what he is getting. He is not very maneuverable and has to scooch around, unable to turn very well - picture someone lying on the floor trying to get around while wearing a straight jacket. :p
