I have just set up, 3 days ago, a 5.5 gallon tank with CaribSea Flora Max substrate, najas/guppy grass, subwassertang, java moss, and a 12 inch Finnex Stingray LED light for yet to be purchased neocaridina shrimp. I have ordered some mini pellia to also add to the tank. I am soaking in separate containers some red lava rock for attaching the java moss, and mopani wood which is still leaching a lot of tannin after about a month of soaking and changing water out every few days. I have an extra sponge filter that has been in another established tank for about 4 weeks, and which I will transfer to the 5.5 gallon tank. When should I move the sponge filter over to the 5.5 gallon tank? I understand that the good bacteria will need a nitrogen source once I move the sponge filter over. What will be the best way to provide the nitrogen source? I have a master test kit and understand that I will need to test ammonia, nitrite, and nitrate to determine when the tank is cycled. And how long should the tank be set up to establish sufficient biofilm for the shrimp to feed on before adding them? I'm trying to determine the next steps for best success with the neocaridina shrimp, which will be new for me. I live in central Florida and maintain winter house temps to at least 68 degrees F, so I don't think I'll need a tank heater. Let me know what you think my next steps should be. I'm holding off on ordering shrimp until the tank is ready. Thank you.
