I wouldn't add anything until the cycle is finished, especially shrimp. If you have a tank that's already cycled you can add some of the media to the new tank filter to help speed it up. Another option is put your new filter on your cycled tank for a week then transfer it back to your new tank. Any which way you slice it I would not add shrimp until you get 0 ammonia/nitrites and have your nitrates under control.
Just my opinion.
My filter was already transferred , ive got a sponge filter running atm on the old tank and thats it. There is no filter media but could i just use some of the substrate and put it into the filter its the JBL greenline M, so its got a compartment.
Or if there are any liquid quick starts to convert the ammonia?
