Just noticed you said 'thinking of adding tigers, would caridina work as well?' or something of the sort, just checking that you are aware that tigers are a species of the genus caridina? Those parameters should work brilliantly though for tigers and probably most other dwarf caridina (as opposed to like aussie natives or amanos and stuff). Tank looks fantastic!
That looks great and I'm sure shrimps will be very happy exploring and grazing in there.
I look forward to hearing how it goes this time. I don't think anyone over here is sending shrimps (or fish) at the moment so I am not planning to get anything here soon, the fish are doing well in that tank, and there is 1 red steel shrimp survivor which shows itself occassionally?
Good to see you back and hopefully this time all will go well!
Tiger shrimp would probably be best as a TESTER as they are less fragile and more adaptable to different parameters than Taiwan bee, so I would get a small group of those and see how that goes at this stage, you can change (or mix?) to the Taiwan bee if all works for a few months?
With the correct parameters the PH should stay stable unless there is something like rocks that alter the PH. Using RO water plus the shrimp minerals will provide all the parameters at a set balance.
I'm not aware of any changes since you posted the pctures back in April so can only assume it may be file size related, can you do one at 1mb or below?
