Do you have baffles in your sump?
Umm..yes and no..
I have over three years of research into this build and i think my biggest mistake was believing the hype on the sump i bought. ..
I'm using a proflex model 4 ..with some mods,
mod one was i used limo tint on the outside of the sump , on the back, sides , and in the front only where the refugium is , this was so my stand doesn't look like the closest in poltergeist ..!
2. I installed a plastic bar and siliconed the adjustable door between 1 and 2 so it would not fall down in the event of power outage. .by doing this it caused a waterfall effect into the refugium, so i had to raise the out put from 2 to 3 ..
And by doing that...it caused a LOUD water fall into the sponge baffle between 2 and 3 .. so i added coarse filter media to quite it down ..
now onto 3.
in there i have a heater, a rack to hold my 46 ozs. Of chemi pure elite. My a.t.o. and protein skimmer. .coarlife super skimmer 220g.
With a bubble trap , and i added a 200 micron sock to the output last week..
now the skimmer has been running for at least 2 weeks and I have it set wide open .. but with no bio load.
