I just converted one of my shallow tanks to high tech. Originally I was going to buy some high grade blood marys for this tank but I've always wanted to keep caridinas like taiwan bees and am now fixated on the idea. I'd like some advice on if my water is suitable for caridina species, and if so, which sub type would you suggest? My first choice are taiwan bees, specifically shadow pandas, but I would also consider crystal reds if they are any hardier to my conditions.
My kH is 3-4 and gH 7-8 which is where I am getting hung up. It is literally just outside the suggested range for caridina shrimp. Given those parameters, are they able to comfortable survive? I'm not interested in having them breed as it is a display only tank.
I inject co2, approximately 30ppm as my drop checker hits the perfect lime green color. I do have it on a solenoid and a timer so the co2 turns on an hour before the lights and shuts off an hour before the lights shut off. It is a shallow tank with heavy surface agitation so good dissolved oxygen (that gasses off a lot of my co2 apparently because I'm running 2-3bps in a 5 gal).
I have an active buffering substrate (uns contrasoil) that is fresh but no longer actively leeching ammonia. The filter is very mature, it's just been rescaped 2 weeks ago. Water parameters are consistent. I also have to top off the water every day since it's open top. My pH before the co2 comes on is a 6.2, however when I take a reading while co2 has been on it just registers on API liquid kit as 6 but I know it's lower (test doesn't go any lower than 6). I'd assume probably in the low 5 range with co2 on.
I haven't been able to test TDS yet but I have a pen coming in the mail and will post the TDS after. Assuming that my TDS is within a suitable range, do you think I could keep caridinas (like tbees) in my tank? I keep fresh purigen in the canister if that makes any difference. I'm not interested in using RO so fingers crossed my tap is low enough in TDS that as long as I keep ontop of matinence and regularly test TDS in between water changes shouldn't be a problem right?
