replacing fluval fx5 outter sponge blocks

[arowfan]

Hey guys, I have 2 fluval fx5s running on my 300 right now, and its time to change the outter sponges on the baskets (see pic below). All 3 baskets (at least 2 baskets) are filled with either scrubbies or ceramic media on both fx5s...Question is, can I replace all the outter sponges (2 to a basket-so 6 in total per fx5) on an entire unit...then wait about 10 days, and completly replace all of the outter sponges on the other unit, or should I do something like replace half, then a couple days later replace the other half?
Thanks,
John

i would change it all out if you have at least 2 layers of bio media. if you wanted to be safer, change out half one week and the other the next week.

either way, the bio media will keep your filter seeded and continue filtering the tank.

yeah, just to be safe, I think I'm just gonna change 2 baskets sponges, and then wait a week to change the last one...thanks man!!!

Why are you changing the sponges?

Since you have 2 FX5's, just do one unit at a time. The sponges are mostly mechanical since you have the baskets filled with other media.

I would just wash the sponges if they are really dirty put them in the washer on gentle cycle and no soap then let air dry

+1 Why not rinse them off? That's what I do and it works great, are they torn or something?
