I thought that it might not have been sitting properly, so I took it out and looked at it, cleaned it a little, and placed it back in a n umber of positions, ensuring the suction cups were adhering properly, and it still makes a rattling noise. I've heard of the same thing in a number of other posts on Reef Central an Nano-Reef.com... Also have heard of the pump failing on numerous occasions...
Can you explain why the increased suction through the intakes would be a concern? I'm not sure I follow you...
As for the excessive flow through the filter chambers, it's really only going up 1.6x the flow from the baseline... Will this make a huge difference? Maybe, depending on what I use for filtration. Remember, I have trimmed the slot that funnels the water to the back of the first chamber, and this allows for more even flow through the second chamber (and eliminates the option of using the trickle filtration with the bioballs)... Possible a little too much for a
refugium, but definitely not too much for chemical filtration or a
skimmer.
Thanks for your reply, you've got me thinking for sure!
