We are in the 6th week of fish in cycling on our 29g tank and have to do almost daily 50% water changes at this point due to ammonia spikes of 1-2 ppm. Still no signs of nitrites or nitrates. Is there anything else we can be doing here? We will not add any more fish until we have cycled. Have 2 guppies 2 swordtails and a very small cory catfish. My 12 year old is just aching to get her community tank going.
