The existing filter can come out (rotate and unclip), I ran my Aquis 500 inlet through that hole. Had the outlet across the other side, poking through the hole the water flow from the original filter went through. It worked well for many years.

We have two distinct circus rides that happen with smaller slices of courgette floating on the surface. 1. The merry-go-round where 2 or 3 little Bristlenoses all latch onto it and end up spinning round in the water like a carousel. If it was me in there I'd get dizzy and throw up! 2. The rising/sinking tide. Depending on variables the carousel will start to slowly sink when more BNs join in. The downwards drift reverses when one decides to go elsewhere. Up and down. I have had my 77 year old father sit in front of the tank and count the number of up-downs in a rowfor us (he was loving it). 12 cycles before the teenagers enthusiasm diminished and some of them went looking for algae.

One question; do you find that the courgette dissolves into soft soggy bits, if not eaten, and clogs up your filter at all? Any solutions or tips to avoid this? Perhaps more BNs??

But with a good supply of BN you don't need to store them for long...
