Ok, Ive had my mate had a look at this and he has made quite a few improvements, can I do anything else or does this look ok?

Thanks,

looks good ,but why so many sections of bio-balls and rings?
and also what is going to be your water level,reason i asked,is how will you distribute the water flow evenly over the last sections of bio media or are they submerged?
 
Leave out the last divider next to the pump and raise the media onto a platform to allow for this. You want the water going under a divider rather than over the top as you will likely get bubbles in your pump reducing efficiency.

Prob because I am a sump newbie and being using cannisters for years, so I am stuck with the cannister mentality ;)

All the media will be submerged, except for some of the pads on the top in the first chamber.

Better now? Thanks.

From the way I look, there is no way the bioballs can be in a W/D setup while the sump is running as the tall second baffle means water need to rise up in the first chamber (high enough to submerge the bioballs) before being able to overflow into the second chamber.
 
i would also make the baffles within the bio ring chamber lower to reduce any falling water noise.. other than that, looks good.

There's only 1" gap between the bottom and the baffle in the bio ring chamber. Did you mean I should reduce this? or are you calking about the baffle in the middle?
 
I would suggest reducing the number of baffles and look very hard at lowering the level of the baffles. With tall baffles, you have a high water line, and that reduces the amount of overflow you have for the tank to drain in the event of a power outage. I would also suggest that less is more when it comes to baffles.

However, if you are keeping the baffles, I would suggest a raised baffle as the last one (closest to the pump). This will allow the water to flow under and eliminate the bubbles from water splashing over the last baffle.

Personally, I think you will find your design to be a nightmare to clean. There will be an accumulation of detritus, and it will be a pain to get out of all those small chambers.
