Welcome to AquariumAdvice.com!!!
My suggestion is that you do a "fishless" cycle. There is some good info in the Articles section at the top of the page about it. Cycling with damsels is a pretty "old school" technique and now considered out-dated. Plus, it is very hard on the fish to be exposed to toxic and poisonous conditions. You would be best to bring them back to the LFS
. Cycling using the fishless method is very easy and usually takes less time then using fish. Simply go to the grocery store and buy a raw shrimp. Throw one or two in the tank and wait. As the shrimp decays it will feed the cycle. Test water parameters (NH3
) every couple of days to see your progress. There is no need to do any water changes during this time as there are no fish in the tank. This is what makes it faster. The "Cycle" product will not really do much to prepare your tank for long-term habitation but will not hurt much either. I would consider adding more LR
if you can, or purchasing BR at the very least. Good Luck!
