ok so i use poland springs water, i buy it as a 6 gallon case at bj's wholesale. i dont use city water at all because i can smell the chemicals is it. i figure if i dont drink it my fish shouldnt live in it.
the only chemicals i put anywhere near my tank are fish safe. i clean the outside with
API safe and clear, i also use their stress coat and zyme.
i have been experimenting with new foods like
brine shrimp and tubiflex worms. these suplement blood worms and tetramin crisps. i feed the corys hiruki sinking wafers, and an ocasional algae wafer.
the acctual tank set up is a 55 gal tank i bought off a local fish store while they were upgrading their tanks. i use a fluval 405
canister filter, a tetra 60 air pump and an AGA 100watt heater.
the 3month old angels were the last living thing i had added to the tank. although i did add 3 more fake plants and a new bubble wand about 2 months ago.
before each fish died they all started hanging around the same spot against the back wall. it is a very sheltered spot near the bubble wall. the only bulge i have ever noticed with my angel is a swelling in their belly after they eat which is normal.
as for the hardnees of my water i am unsrue of that, i have nothing to test it with.
