I only mentioned these filter bags because someone mentioned that 7" was the largest size.
I only have two fish. But I will be using a large holding sump. It would be silly to use small filter socks with this sump tank.
With the large grids on my external overflow boxes, any uneaten food will go straight into the sump.
I'm aware of that. Am considering doubling up on them. Want to make my own bags, but haven't found the appropriate material. Plan on using four or five in my sump. The main purpose will be to catch any debris passing through the overflow boxes. My main mechanical filtration will be from six Pentair Rainbow RTL-100s. There will be seven 1 1/2" uptakes in the tank which will hopefully, pick up the majority of the debris.
I was planning on using the sump as strictly a holding tank until I saw these large filter bags. In addition to using these 5 gallon filter bags, I'm now going to throw in 20 L of Pond Matrix for some redundant biological filtration. After thought filtration
Your going to use 6 of these filters? At 180+ a pop is crazy. filter replacement has to be around 70 per filter yes they can be cleaned but still seems a bit redundant and overkill for filtration? Don't get me wrong its your tank, but do you need that many?
