Given the lack of formal reviews out there on this Coral Box line of DC skimmers, I figure I'd start this thread for current Coral Box skimmer owners to show off their skimmate, share their settings, reviews, and as a place for people to ask questions.

:thumbsup:
 
I have the D700 on my 120 with a 40B and it is working great so far. Pulls a very dark skimmate (especially since I started carbon dosing) and is very consistent. The adjustment is super easy as well and I maybe tweak it every few weeks but that is usually because either I or my son bumped it. The skimmer is in about 6.5" of water with the pump turned all the way up.

Overall I like the D700 more than my old curve 5 just based on the ease of adjustment. Seemed like I was constantly tweaking the curve 5 as it was difficult to get it just right. Then again, the curve was my first skimmer so it may have been my inexperience that led to the fiddling....
 
The d700 is working well for me. Suprised by the g.reat build quality. So quiet, and easy to adjust. Great space saving design. I have only one complaint, the skimmer cup is hard to remove.
 
I agree with everyone about how quiet it is. My D300 was dead silent at first but slowly developed a very slightly humming noise that can't really be heard unless you stick your head close to the sump with the doors open.

I'm still trying to dial mine in... Will post skimmate pictures shortly~
 
which coral box skimmer would fit a 80 gallon display and a 30 gallon sump with medium bioload? at some point i think the bioload will get heavy though.
 
I'm currently using a D500 on my 40, total volume of around 50 gallons, and with fairly heavy bioload. Pulls skimmate like a boss.

The cup has gotten a good bit easier for me after taking it off about a half dozen times for cleaning. The first few times I thought I would never get it but now it is not bad at all.

I've noticed similar with my D500. It still makes me cuss it every time, but not nearly as badly :cool:
 
Waiting on a new Bubble Magus Curve A5 - it looks very similar to the Coral Box D500. My vendor does not have the Curve A5 in stock and I was debating cancelling the order and getting the D500 instead - it if for a 75 gallon FOWLR that I am setting up - any advice would be appreciated.
 
I had the curve 5 for almost 3 years with no issues but have only had the D700 for a few months so I can't say much about its longevity. Honestly, I would say they are fairly similar with the D700 taking a slight edge on ease of adjustment.

Thanks
 
Finally took some time to take some pictures of my skimmer's performance so far. After a few adjustments, I finally got it to skim fairly dry. Could be drier though!

I have a d300 on a 60g cube/40 breeder setup. I have not yet had a chance to set the water level with a skimmer stand, but I am extremely impressed with the performance. I've used dozens of skimmers and I would recommend this to anyone. Addictive Reefkeeping has these as well for a bit better price than fish street. They are my go to for jebao.
 
Bump
I got a D500 running at 8 inches of water. Seems to pull dark coffee colored skimmate out , but amount varies all the time. 8 inches at 100% gate about 40% closed
 
resurrecting this thread:
Got a D300 a week ago, looks sleek, super quiet, not pulling out much at first, but getting better day by day.
However, after five days the pump is rattling LOUD, sounds like rocks are in there. Still skimming, but who else has had these pumps start becoming more noisy?
 
My 700 has been quiet as can be for over a year now except for the times snails or other foreign objects got sucked into the impeller. I would take the impeller intake horn off and make sure it's clear.

Thanks. I took the skimmer completely apart and just had the pump run, shook it around some, it stopped making so much noise. Then put the skimmer back together a piece at a time, plugging in the pump as I added each piece to see if something was rattling. Got it back together and now it is dead silent. Will watch it over the next few days, maybe something got stuck in the impeller and fell out when I shook the pump under water?
 
I have a D700 on my 90 gallon sps tank. I've had excellent results from it. It's super quiet, uses very little energy and has been easy to work with.

I did have to replace the bottom screws because the factory ones strip out easily. I changed them to hex nut screws that I can remove with my fingers rather than needing tools.
