Yes they do @Wookii you simply unscrew the unions and those sections slide out. Allows the lid to be removed or for the whole box to be lifted out for maintenance (every three months).
The water level is below the sponges deliberately, this is controlled by a) how many holes you drill for the trickle plate and b) the size of holes you drill. 1mm-1.5mm holes are plenty big enough and with enough of them flow through will be more rapid than you would expect. Water doesn’t really get a chance to build up in the box.
Water falls down onto the sponge and the noise is suppressed as there is no water breaking/bubbles bursting to create noise. Just hold a saturated sponge under a running tap to experience this, exactly the same inside the filter box.
The holes drilled into the bottom of the box also trickle gently onto the K1 media underneath. The system is silent. You would have to open the cabinet door and put your head close to the sump to hear water movement. It was a priority of the design as it is located in the living room.
So do the sponges in the trickle box not act as pre-filters, given 4 weekly cleaning - is that done more via the black sponges in the overflow? How often do you have to clean them?
Reading more and planning on my own sump, your idea with the sponges in a sealed container looks real good especially that it is quiet as you say..
Just for a bit of perspective this is 4 x Kessil A160’s @ 100% through 2ft depth versus two ONF Flat One’s @ 35% through 1ft:

Fully aware I’m being an utter child but it’s still making me giggle. Can’t even get a clear shot.
As for growth:

When everything that got planted 48 hours ago is as tight growing as the H’ra in the foreground (that went in a week ago) can see this being a lot of fun.
PVC plumbing. Now... I can confidently say welding PVC plumbing together in your shed, by torch light, in a respirator mask, at 3am, not only raises a few eyebrows from the neighbours.
But if you do it whilst drinking beer it invariably leads to some mistakes:
For those in the know you’re already laughing
For those that don’t, those nut thingy me jiggies are meant to be on the pipe before you weld the ends on.
Always a good idea to buy extra’s with PVC if you’re a plonker
Looking great... Trained your young Padawan well you have!Ethan’s trim not too shabby for a six year old on a set of steps
Nothing wrong with that John boy.gone all FarmVille lately
Where do you get your co2 from mateMonitoring the Co2 situation before starting up the AS1200.
Yeah with social distancing cant really scape with Dolores lol how are her tanks coming alongI think the comp tank idea has well and truly been shot to hell.
That would be tight for a 1200If supply becomes dependable on gas then will likely plant the AS1200 out using plants from the AS600 and the 10l shrimp tank that is comprised of specimens from the old 4ft tank
We are all good jemma is still at work so been home with ollie for 5 weeks now love him to bits but I've never had 5 weeks of work so struggling with the boredom a little lolHope you and yours are keeping well.
