Help: My bioblock keeps floating off! (Help me build a better bubble trap?)

[chaostactics]

So I have a older Red Sea Sump running on my SCA 80 aquarium. I just upgraded to a Red sea RSK 300 and I hate it.*

The sump has a double baffle before the return chamber. I have pieces of bioblock cut to fit in there but as it traps bubbles it gets boyant and tends to float up in the baffles and even rotate some times. I'm so frustrated with a display full of micro bubbles.




*The bottom discharge design means the outflow can't be redirected to another chamber or some sort of bubble trap.

Have you tried putting some live rock on top?

Honestly that would be a pretty good/easy solution. I haven't but mainly because I have trouble getting pieces small enough to fit between the baffles but big enough to be heavy... maybe time to revisit that though...

Cut some filter pad to fit in there. That’s what I use on my diy sump. You can get a 10 ft roll for like 9 or 10 bucks when it’s on sale.

I'm not able to easily reach the baffles. It would be a 15 min job to change out filter pad.

I would break up like 2 larger rocks with a hammer and just drop them on top. Wash them off in some saltwater tho because they can make a dusty mess when broken.

I didn't really have any large chunks to do this with but I forgot that about a year ago when I started my tank I put a whole bunch of rubble in the chamber where my drains enter my sump to give out to new reefers to seed their tank. I had stopped giving out rubble and actually were giving out small chunks of extra by a block I had that crumble off the pieces I put in The baffle. I was able to come up with enough that I think The block is now pinned down well enough.

@Brandon3152134 while I had the sump Apart to rearrange the by a block and use Rubble to keep it in place I came up with this idea for a bubble trap/ biofiltration with forced water /skimmer riser. https://www.reef2reef.com/threads/d...p-and-bio-filtration-2-1.772364/#post-8153920
