The filters (with the bacteria) etc would still be running in the old tank happily with the shrimp and the old substrate as it had been? Could some dirty water (with sponge squeezed in to it) be used in the bucket?
The instructions for the JBL soil I am using is:
Use: Rinse the substrate briefly under tap water to wash away any abrasion caused in transport. To avoid accumulation of minerals in the water, carry out a 50 % water change every 2 to 3 days in the first two weeks after filling.
It isn't actually anything I need to do soon so don't want to waste too much of your time, but it would be much easier to have a bucket in the bathroom with the soil for a couple of weeks etc if you need to keep doing water changes every few days until the soil has settled down, ie the (above mentioned) mineral build up cleared and/or some soils I believe have an ammonia spike (doesn't this mean the soil must contain ammonia) etc early on so would that still happen in the bucket without filters and heater etc?
JayC don't waste too much time on this (I appreciate your time) as I expect I am just not experienced enough to understand!
After more observation, i can confirm that they react less to my presence in the tank than both neocaridinas and caridinas babaulti; i have not performed testing for "out of the tank" visual stimulation.
I know this is a bit out of date as a topic, but I have been wondering for some time about this.
Can you just put new substrate in a large bucket with dechlorinated water (no heater or filter or anything else) and let it do its thing, cycle, ammonia spike etc, change the water weekly (or when an ammonia spike happens). Then put it in the shrimp tank setup afterwards so as not to 'risk' the shrimp or have to set up another tank to transfer the shrimp too etc.
I'm sure there must be a reason why you can't just do this as it sounds way too simple, so wouldn't everyone do it??
