1. Size of aquarium (# of gallons) - 30
2. Is your aquarium setup freshwater or brackish water? Fresh
3. How long the aquarium has been set up? About 2 weeks
4. What fish and how many are in the aquarium (species are important to know) - Mollies (I think - they were rescues...) 4 white, 7 black
5. Are there live plants in the aquarium? no, but I'd like some (especially if that would help)
6. What temperature is the tank water currently? 73-75
7. What make/model filter are you using? Penguin Power Sponge Filter
8. Are you using a CO2 unit? no
9. Does your aquarium receive natural sunlight at any given part of the day? not direct
10. When did you perform your last water exchange, and how much water was changed? 2 days ago, 5 gallons
11. How often do you perform water changes? once - twice a week
12. How often and what foods do you feed your fish? Nutrafin Max Complete Flake Food, 3x per day
13. What type of lighting are you using and how long is it kept on? florescent 8am - 9 or 10pm
14. What specific concerns bring you here at this time? High level of Ammonia - other levels are hig, but not as bad
15. What are your water parameters? Test your pH, ammonia, nitrite and nitrate. I haven't had a chance to test yet this morning, but yesterday, I go pH = 8.2, Ammonia = 1.0
, Nitrite/nitrate = 0.2
16. What test kit are you using and is it liquid or test strips? liquid, Red Sea Fresh Lab
17. When was the last time you bought a fish and how did they behave while in the pet store tank? I got 13 fish from a banquet about two weeks ago (they were part of the table center pieces). The first night they were cramed in abot 10 gallons. The next day I set up this tank for them.
I've lost two of the original 13 (both the white ones). I think they are mollies, its what thiey look like, but I could be wrong. Per petstore people, the tank has Freshwater conditioning salt in it. I was running a heater (Hydor Theo Heater 50W), but it wouldn't turn off (temp got to about 79 when the thermastat was set to 72...).
My main concern is that I lost two fish to what appeared to be swim bladder failure. Thats what prompted the testing of the water.
I know I need to just keep changing out water, but is there anything else I can do to bring down the ammonia level? Would plants help? I've had fish tanks for years (though never this big - except for the pond) and I've never had this sort of problem before.
