My sump is designed the same as his and I don't have any issues. My experience was when I have enough light for the Chaetomorpha to grow it renders the skimmer useless. I took out the reef octopus skimmer I bought because there was little to skim anymore. An expensive lesson, since it's sitting in my closet unsused now.
I have 2 18watt 6500k spiral compact flood lights (spiral bulb inside a flood bulb "75watt equivalent") over a very small refugium section (8x12x10) and the bulbs are only an inch or so away from the surface. I grow chaeto so fast I haveto toss a huge clump every 2 weeks, and have had undetectable nitrates since the first 2 weeks. For your setup I'd suggest 3 to 4 bulbs and much closer to the water than you have now.
I'd nearly guarantee the sand in the return is causing the majority of the cloudyness. When the water level gets low in the return side the water running down the baffel will shoot straight into that sand and stirr it up. My water level in the return section goes down several inches in a day.. It's due to evaporation. I haveto top off a gallon a day (65gal display, 20gal sump) That spot should be the ONLY area where the water level changes. if it changes anywhere else for more than a minute or so there is a problem.
As long as you can turn off the pump and the sump doesn't overflow; the baffel height is fine.
how do you thing this will work.. lights about a little less that 1 1/2 above the water
only problem i got is i got my return pump hard piped and cant get the pump out to remove the sand... any ideas how to get it out without cutting my pipe
but my big concern is about my lights... what do u think
