Thanks Glenn!

Nice sump Terry

Thanks Anthony.

Just a quick update. It's been 6 days and my new Euro-Reef sump version is breaking in now and beginning to pull out gunk. I just took a quick picture - this is about 22 hours of skimmate:



Running a bit wet, but that's OK as I can adjust for that if I want to, by raising the skimmer or adjusting the plate on the bottom.

Robbert (nanoskim) - if you read this thread please give me an instruction on using the adapter on the bottom that covers varying sizes of holes. What effect does a large opening have versus a small opening? I haven't had a chance to try that adjustment yet.

Thanks

Reefmack do you have a large bioload in your tank?

[Reefmack]

Yep - not as many fish as I once had, but I'm still overstocked per most folks conceptions (or misconceptions ), plus I overfeed at times

Keep in mind that I really hadn't been skimming anything for 5 days, till the E-R started to kick in yesterday.

I would assume that one of the holes (probably the larger one) should be unrestricted so your flow is not too impeded, while the other one is the "fine tuning" hole that gets partially or wholly blocked by the rotating plate to produce more backpressure (like a wedge pipe or gate valve). What this accomplishes over simply raising/lowering the skimmer in small increments is unclear.

Just guessing though...hopefully Robbert can clarify.

I did notice when I first set up the skimmer that which holes were covered made a big difference in the water/foam level in the skimmer. But I can't remember if covering more of the holes raised, or lowered, the water/foam level in the cylinder. I think using the smaller inlets on the bottom raised the foam level, but cannot remember! There are several holes, varying from small to large.

Looks great Terry! Did you get the new design impellers in your Sump skimmer? Not sure Todd, Robbert have them ready to go yet.

[Reefmack]

Tom - nope - I just cleaned up the ones I had been using - same wheels, pumps, airlines & mufflers - just a new cylinder. I don't think the new wheels are available yet.

OK thanks!

Restricting the flow by any amount should raise the water level in the skimmer and produce a wetter skim.

My skimmer is a bit touchy with the height adjustment: 1/8" up or down can make a huge difference in the wetness of the skim. Not so easy to slide in small amounts. Perhaps the restrictor plate that you have is a more precise way to adjust.

If you need adjustment, I would have the restrictor block only the smallest hole first then progress to include the next smallest and so on. This should give you finer control than blocking the largest hole first.

I'm pretty sure when I first set it up I ended up having only the smallest opening uncovered, since at set up I think I was trying to get the foam higher, so that makes sense. I think that's also what I'm seeing if I try to see the plate through the side of the sump. I too have noticed that a height adjustment of as little as 1/4" can have the cup filling with water too quickly, or having the foam too low. The bottom plate adjustment would indeed seem to be the thing to use for fine adjustments. From what I recall, adusting the plate showed up as an immediate effect on the foam level. I'm planning on trying some plate adjustments this weekend. I've not wanted to do too much fiddling with things till the skimmer was through the break-in period, but I think I've reached that point now. Thanks for the advice!

Hi Terry,

My original intent for using the bottom plate adjustment was to allow leeway in the original (coarse) setting of the foam level in the skimmer since there is such a huge variation in water levels and organic levels from tank to tank which was driving me crazy. The bracket adjustment was meant to be the secondary finer adjustment... oh well, now it appears that different users have different uses for it which is fine as long as it works ok.

My suggestion is to set the foam level below the transition at the point where the bubbles start to shed water and get larger and leave it there or else you will find that the cup will fill up fast with water due to the large amount of foam trying to get out of a relatively small exit ( foam riser diameter).

Never a dull moment in this great hobby!

Cheers,
Robbert
