35ppt Posted February 16, 2017 Report Share Posted February 16, 2017 I set up a new plant only 29G tank a few months ago. Somehow I forgot about the fact that there is no nitrogen cycle, and I put 2 ghost shrimp in there. I do not have another cycled tank I can move them to. I do have a 10G with 2-4 RCS in it. I set this tank up a few months ago with fresh substrate and switched to remin. RO. I used the established filter from the old tank. Shrimp seemed fine at first, but eventually I noticed the numbers just droped one by one. I really have no idea why these shrimp are dying. So I don't want to put the ghosties in this tank. However, I did take a sponge from the RCS tank to try to seed the ghost tank. But I don’t even know IF the RCS tank has a cycle going at this point with that amount of shrimp in it. There has to be a minimum amount of nitrogen to start & sustain a cycle, right? I don’t even know how to check a tank for cycle, now that I think about it. Even kind of wondering if you can keep a small amount of shrimp in a large volume of water without a cycle. Just thinking about the small jars and bowls people keep with shrimp + plants and no filtration. So I really don't know what to do about either tank - the 10G with 2 RCS or the 29G with 2 ghosties.

chappy6107 Posted February 16, 2017 Report Share Posted February 16, 2017 how heavily planted is it? if it is pretty full, some tanks will not need to cycle as the plants take up the harmful ammo/nitrite/nitrate faster than the bacteria can. and you need a test kit to check the tank for completed cycle.

35ppt Posted February 16, 2017 Author Report Share Posted February 16, 2017 Good point. The 10gal is lightly planted but the 29gal is heavy. NitrAte is zero on the 10gal, and I will of course be checking the 29gal now that I've shrimped it. Quote Link to comment Share on other sites More sharing options...
