We continue to get request for sump kits designed around the Triton sump parameters. We have a basic design drawn out, but we thought we would share it in the hopes of getting the insights of other reef keepers. In our humble opinion: The skimmer portion is easy. We can just use one of our standard skimmer sections with media basket, but with it installed backwards. This way the water must go under the first baffle, up through the media, then over the adjustable skimmer baffle. Triton says that because the water must go down and under the baffle, more proteins will rise to the surface and stay trapped in the skimmer section. I should add that all images below have the water flowing from right to left. The refugium section is a little more difficult for a few reasons. First, they suggest 10X turn over through the sump. This means a decent amount of flow going through the slots of the refugium baffle. Typically, the only way we’ve been able to make it completely silent is to raise the skimmer section level up to right below the teeth so that it doesn’t make any noise. The issue with this is that you now must run the skimmer on a stand, and that really defeats the purpose of having an adjustable skimmer baffle. Also, it makes you needlessly run the water level in your sump higher than you other wise would. This decreases the amount of water that the sump can hold when your return pump(s) are offline for cleaning, service, or power outage. Our solution to this is to add another set of teeth below the water line of the refugium baffle. To tune it so that only a tiny bit of water flows over the top teeth of the refugium, a sliding plate is installed over the slots. By raising or lowering that plate, you can finely tune the amount of water that flows through vs over the baffle. We have tried this before and it works well. The only issue in theory would be that when the pump is turned off, the skimmer and refugium section would equalize. If the refuge was completely full of macro algae, there is a chance that the water level could drop, and the top of the algae not be covered. However, this has not been our experience yet, and with a typical setup, both the skimmer section and refugium section are above the upper teeth of the refugium. But, it is something to keep in mind. The next issue we see is with the refugium being full of algae and clogging the teeth of the baffle. We have seen other designs where people would put a small plate in front of the teeth blocking light and broken off pieces of macro algae. Our design would use 4 sets of nylon (same thing the thumb screws are made of), either ½” or 1” long to mount a large plate to the front of the refugium baffle, covering both sets of teeth. We can see a few possible benefits. First, it would keep the large dense mass of algae from getting to the teeth. Second, it would act as a light blocker, cutting down on the algae that would grow on the teeth. Finally, with a typical setup, water would only be drawn across the top. With it being drawn from all sides of the place, it would also cut down on dead zones in the refugium. The final addition we are considering is a baffle before the refugium. Basically, it would be a baffle where all the drain water would flow under. The thinking is that if the water must flow from the bottom of the refugium, there would be less dead zones, and more water flowing over the entire algae mass. The negative is that it would eat up a few inches of the refugium section. On the 29 and 40B kits, that space is precious. In the 55, they have a lot more length for each section. The question is, would the possible benefit of better water flow through the refugium, and a slight increase in price outweigh the loss of a gallon or two of refugium capacity. Here are a few renderings of what the 55 kit would look like. So, what does everyone think? Is the design good or bad? What would you change and why? We want to hear from you guys, so we can turn out the best possible product at the best possible price point, and most importantly…..Get it right the first time!
