as noone else chimed in lol Im going to take yr advice. maybe a little under 2 tblspoons per 5g until this tank is cycled. Did 2 x 50% waterchanges yesterday and when I tested at 7am this morning nitrites were over 5ppm!! Madness

well after adding new bacteria from your old tank it will still take a bit of time to establish, but just start with a little salt and work your way up. bumble bees don't need too much salt, they just need something, depending on the species of course.

...and theres the rub. Its almost impossible to id these fellas. Even breeders have to put them under microscopes to see their bandings to id them. Ive done so much research and am convinced that BBG cant live healthily and for long in freshwater, but I do think I have been way too heavy handed with the salt lol.... Cant believe this little tank is causing me so much grief. Its the only darn tank Ive ever had that refuses to cycle or stay cycled and its had the top end equipment installed and according to the experts its pretty much a penthouse in the BBG world. I think yr right, the established media doesnt happen straight away as people lead one to believe. Its day 3 now and still the nitrites are over 4ppm :( I feel another water change coming on

Hello Brackish,

I also keep brackish tanks. I use a Instant Ocean hyrdometer. This one goes all the way down to 1.000, making it perfect for low end brackiish. I would have to do some reading up, to recommend a Specific Gravity for your fish. What brand of salt you are using and how packed down the salt is, can make a difference in the amount you use, so using the hydrometer is the safest route for brackish.

Some brackish fish, can be sensitive to quick changes in Specific gravity, so gradual changes are better for the fish and tank cycle.

I cycled my tanks with brackish water. Using freshwater established media, on low end brackish, (like you are doing) will help. Using freshwater media in high end brackish, you will have bacteria die off.

For now, I would keep up with the water changes to keep the tank as fish safe as possible. Feeding contributes to poor water quality, so stop feeding for a few days, or feed very little. Your tank, will finish it's cycle with time and patients.

speaking for most bbg species your right they do require some salt for healthy conditions, but the salt level is fairly modest. you can brows the internet for hundreds of care sheets that will tell you an optimum specific gravity ranging from 0.005-0.008, but i wouldn't want to link any source other then wetwebmedias articles to insure credibility.

anyway, 0.005 should do just fine for them. if you ever want to breed them just drain some water and replace it with cool freshwater.

thanks for yr help everyone. Im pleased to say that after many water changes and lowering the salt right down to 0.005 the tank cycled and has remained cycled! phew. You know what its like when you dread doing the morning water testing I would love to breed them but another member has told me that nitrates need to be very low in order to breed and unfortunately I live in an area where the tapwater contains 30-40PPM. I think that it scandulous personally and actually asked them to put it in writing as to begin with I thought my test kit was wrong. But no. hovers around 40PPM. My main tank is a very heavily planted tank which has helped to suck up some nitrates but hasnt had the effect I thought it would as that also hovers around 20PPM. Bummer!

Cool

. ...The tank seems to be going thru one cycle after another and I dont understand why. Ive barely fed them since the waterchange yesterday but am wondering if it could be the frozen daph thats causing these mini cycles and repeated spikes? its quite tricky to get the right quantity but they go crazy for it. I just dont know how much longer my poor little bumblbees can survive this.
Many thanks for anyones imput.
