i had a fish kill when i just washed them and the filters for my 350gph are 10 bucks a piece (it holds 2 filters).
I know i am spending too much on filters, that's why i started this thread.
I don't think that people are looking at the amount you spend per say, I think they are questioning the practices that lead to spending that amount.
My guess would be the fish kill resulted from washing the all cartridges at the same time, wiping out a vast amount of the bio. Alternate washing one cartridge a week. I did this for many years using HOB water fall type filters.
In all reality a large
sponge filter and a air pump would be enough for your bio, which would allow you to keep one of the water fall type filters for mechanical filtration and maintenance would be just washing a filter element. For a filter element in this type of set up, I have used every thing from AC110 sponges(cut to fit)/floss/pads stuffed into the area for the cartridge. Cost of maintenance is next to zero when doing this, as the filter elements can last several years.
The best thing to do is get away from the proprietary filter element for what ever you are using. AC110s are great off the shelf filters that are cheap to maintain, which is why they are being suggested.
I just bought my first new round of mechanical filtration material in 4 years. Cost $26.00 for 6 tanks: one 125g, two 90g, two 55g and a 10g. All I use is the blue bonded polyester filter material. I buy it by bulk via Graingers locally.
