What did you do with your tank(s) today?

As to crashing the filter, in the past Ive had bacterial blooms if I did too heavy of water changes so I try not to exceed 50% so my tank doesnt turn white. Just past experience with my tanks.

That probably says more about the input water than anything about your filters. I never do less than 50% water changes, and often considerably more than that, and have never seen anything like you describe.

That could be something there, I have had problems in the past. One time I lost a school of roseline sharks within two hours of a 50% water change because I forgot to dose with Safe. Lakewood says they get water from underground aquifers and make it sound as if they are not doing a whole lot but they must be doing something to the water.

That's remarkable given that these Cyprinid fishes (a. k. a. Denison Barb) tolerate such a wide range of temperatures, as well as pH and hardness parameters.
