Alright, Well I now have some updates for some more help. I lost my last Tiger Barb. So now here is all the fish that I have... 2 red Wag Platties, 2 Fancy Guppies, 2 Dalmation Mollies, 2 Kissing Gouramies, and 2 Blue Gouramies. I tested my tank this morning after I got off of work and here are my results...Nitrate 20ppm, Nitrite 3.0, Hardness 150, Alkalinity 120, pH 7.8 and Ammonia is between 0-.25. Those are my updates. Then I did a water change of 50-60%. It's a 29 gallon and I took out about 12-14 gallons. I also got a make-shift filter that I cut to fit, and it doesn't have any carbon, and it is now running with the filter that is hanging on the back. I'm not currently using my UGF with the powerhead unless you guys recommend me to. I also added freshwater aquarium salt (5 Tablespoons: Directions said 1Tbsp per 5gal. of water) and I turned the heat up. I currently don't have the tempature, hence I'm waiting a couple hours for the water to circulate. Any more suggestions are helpful! I haven't got the problem solved yet, but am I on the way?? Thanks!
