i cannot seem to get the water clear. it has a milky cloud to it although its not severe. i have 2 banana plants, the rest are fake. the filter is clean and working. i've done water changes etc. i dont believe i am overfeeding and i've used water clear drops several times. i cant kick it. i've read about bacterial blooms. how does one get rid of that? i think its affecting the inhabitants as 2 frogs came down with dropsy and died, one green tiger barb wasted away over 7 days or so, and the other green barb is starting to show wasting away symptoms. are the green tiger barbs more delicate?
