Hello all and thank you for a fantastic forum and fish site. I have been gleening information for a few weeks here. It has helped me enormously! I have learned what fish are compatible, water testing, cycling...and so much more! I have been searching for an answer to a water problem that I am having at the moment and haven't found anything. So thought I would post and hopefully get some help with this problem. I have noticed what looks like clear and white spore like dust particles floating around the tank. Some are larger than others, others are just dust like specks. The larger ones actually look like a larvae of some type. It all started after one of my platys had fry. She didnt have much and what was there was either eaten by other fish or sucked up into the filter tube. I was able to see a few( less than ten) fry swimming around but were chased quite quickly and ate by the fish. ( sniff sniff...) It came so fast I had no time to do anything. Now days after that I see these spore like floaters. I scoop them out with the net. I am wondering if its possible that it is fry that is broken down by the return flow of the filter? Is this possible? Or is there really something else growing in my 29 gal tank? I have 6 platys and two dwarf gouarmI at the moment. The tank is 3.5 weeks running. I have been doing morning water tests with the Mardel 5 in 1 test strips. The readings are as follows: PH 6.4; Alkalinity 0; hardness 50; Nitite 0.5; Nitrate 20. I am doing a partial water change every five days, taking about 4-5 gals of water out and replacing with tap water (well)& treat with prime. I have no live plants, only silk artificial ones. I would like to add a betta to the group tomorrow but do not want to do anything til I know what these spore like items are that are floating around.... any suggestions? OHHh the only new thing Ive added before this problem was feeding them frozen blocks and I have the multI pack. I have given them one cube of the spirulina enriched brine shrimp. can this have anything to do with the spore like dust? Or have caused it? Thank you so much... I just LUV this site!!
