I would not put the canisters in series as during maintenance, you will need to power off both of them.

It will be better for you to service the canisters one at a time as it will reduce the impact on the population of the BB.

i would rather using each sets on it's own.. i would set up each canister on each side of the tank.like wat bro Alvin said is true, better wash 1 canister at the time to prevent lost of BB.

yes you will want to wash one cannister one week then the other the next or next month even. also i wouldnt suggest using them in series as if the first gets cloged you will run the second empty and this will shorten the life of the cannisters alot.

With different layers of media fo each cannister, it is almost 100% sure that the flowrate input and output is different for the two canisters.

Whichever has the slower flowrate will have more tear and wear on the motor and blades.

Not a good way to connect them in series. You will have more damage to ur equipments.

I agree with above suggestions.

I wudn't prefer to link 2 canisters, as you can obviously see why from our bros comment.

what I concern fm my input is your media arrangement. put your bio media before mechanical media is not recommended. Your bio media such as bio home, micromec will clog super fast.

I suggest for the first layer you can put ceramic ring as mech/bio media and disburse water evenly to next layer.

then you can put sponge/fine wool in second layer. pls note in mind that quality of wool itself can affect how fast it clogs.

you can put full of bio media to next 3 layers, so you got mech filtered water that flow through bio media. this wud ensure your bio media long lasting fm clogging.

pls note that clogged bio media, wud slightly decrease its surface capacity for BB to cultivate.

just my humble opinion

When ever i service my filters i will always add bb powder back to the system and no wc for around at least a wk. So i don't think it matters a lot.
Just my humble opintion. Thanks for all of your opinions

I will always take note of the flowrate of the water back to my tank, This should settle the problem right?

Oh ya i for got to mention there is a layer of filter mat in the first tray of the first canister and also there is another at the last tray of the second canister. So is there still a problem?
