I havent had time to change water in about 5-6 weeks due to some work and
family related issues. Took time to add treated water though. There seems
to be no ill effects and the water readings are pretty good and consistent
with the exception of the water being a little hard. The water is becoming
somewhat cloudy. What are some of the problems I might come across with not
changing water for long periods?

20 gal. tank
Clown Loaches
1 Pleco
3 Black Molly
2 Swords
4 tetras.

1 real plant (Cant remember what its called but its long and thin and
grows very rapidly)

Thanks

reduction in water clarity is a big one
also the water can lose the ability to hold as much oxygen
the main prob is the water becomes less like the tap water and the fish will
stress more from a large change if you have to do one.
