I recently acquired a 12 gallon Aquapod and decided to convert it into a new planted community tank. I did a little bit of research on what community fish would be good for a small tank like that, and ultimately decided on getting 6 harlequin rasboras and 6 pygmy hatchetfish. They seemed to be nice, compatible community fish with similar requirements. Both fish species like soft, acidic water - especially the hatchetfish, which likes a pH of 6.5 or lower.
I read that the hatchetfish can be a little bit delicate, so I'm somewhat concerned with the water parameters in my tank. Unfortunately, even with a hunk of driftwood and blackwater extract added, the water in my tank is sitting at a solid 7 pH. I'll be starting up the CO2 again tomorrow, but I'm not expecting great miracles out of that. Is there anything else I can do or add to the tank to get the pH down? I don't just want to go and dump Seachem Acid Buffer in the tank if there's a better way around this.
Also, I read somewhere that hatchetfish like dim lighting - I already keep the tank in a poorly-lit room, but should I also limit the amount of time that I keep the light on for the plants? I have a type of compact florescent bulb in my tank that is on a timer for 8 hours a day.
Thanks in advance!
