Just put a ball valve on the line to the scrubber. Then you can adjust the flow just how you need it.

well, im going to put ball valves on all of the joints in the pvc so i can stop the flow for water changes, etc...
thanks!

I am not knocking here santamonica,
But I am not a fan of gate valves. Any that I have used have leaked at some point.
However yes, that is how it should be plumbed.

Alright just tested NO3 and ta da! 0 NO3! Awsome. Still have some hair algae in display but appears to have slowed down. My scrubber is still getting mostly brown slime and some green. Don't really care. It is working. Have to clean every couple days because it is growing so fast. Anyone who is debating trying -quit debating and just do it.

Update: FW cleanings
Pods eating the algae: The reason you need to run freshwater over your screen every week is because you want to kill the baby pods that start to grow and eat the algae. You may not see the eaten areas, unless the algae is very thin like this:

However, pods are always growing and multiplying. And they eat algae. The reason this is a problem is that (1) pods are constantly flowing out of your scrubber into the tank. If they eat algae first, then the nitrate and phosphate that is in that algae gets released back into the water, and (2) you now have less algae to do the filtering. Unlike the picture above, however, the algae is usually too thick for the eaten areas to be seen. The pods stay out of the light, in the underlying layers; so you don't see what they are eating. By cleaning your screen in freshwater, you kill the pods that are on your screen. They will start multiplying again within a few minutes, but at least you can keep them under 7 days old. And even if you clean only half of the screen each week, you still want to wash the whole screen in FW.

Successes Update:
sean48183 on the SWF site: "Alright, just tested NO3 and ta da! 0 NO3! Awesome. Still have some hair algae in display, but appears to have slowed down.

Anyone who is debating trying -- quit debating and just do it."
ScubaDrew on the RS site: "I built a small one using the basic plans posted in the first few pages. I used a dremmel to cut the slot in the PVC and used fishing line through the small holes in the plastic divider material to hold it up. My tank measured 0’s in all the algae related categories prior to building it, but my tank was still growing a lot of HA and some cyano. I’ve only got one florescent ‘flood’ style light on one side of the scrubber right now due to having placed it in an already crowded sump. I had a full coat of algae in about 10 days, and cleaned off about ¾ of what had accumulated at that time. Now I need to clean off a large, heavy, handful every week! With continued cleaning in my DT, I’ve really made progress in getting the DT algae free. Thanks for the info, I think the ATS will be a part of my system for a long time to come."
RiaanP on MASA site: "Scrubber running now for four weeks. NO3 0mg/l (first time EVER). PO4 between .025 and 0.5 mg/l. 4 weeks ago NO3 was over 100 mg/l and PO4 was over 2 mg/l. So a scrubber really works."

if i feed the pvc that is going to the scrubber from the overflow as the only pipe, wont the pipe get backed up since its a very small hole at the end?

You don't need any hole at all at the end. There has not been a single report from anyone of an overflow backing up because of a clogged screen. However, as is shown in the diagram above, if you want to include that optional drain-bypass at the end, you would make it the same size as your overflow, and thus it would be able to handle 100% of the water.

Part 2 of 7:
Taken from "From the Food of Reefs to the Food of Corals" by Eric Borneman
"Nitrogen levels in [natural] coral reef waters are typically extraordinarily low, with most being found as ammonia. This is in contrast to aquaria, where the dominant nitrogen species is usually nitrate. Nitrogen is the be-all end-all for zooxanthellae growth and reproduction [zooxanthellae is what photosynthesizes light into food for corals]. By limiting nitrogen in the form of excretion products, the [coral] polyps keep the zooxanthellae in the numbers and density that maximize photosynthetic efficiency for its own use. Using several released compounds, most of which are still unidentified, the [coral] polyp stimulates the zooxanthellae to release virtually all of the products of its photosynthesis, and these are then used by the polyp for its own needs. If nitrogen was made readily available to the zooxanthellae (for example, if high levels were present in the water and this dissolved nitrogen diffused into the coral tissue), it could then be accessed by the algae without limitation by the polyp, and zooxanthellae could begin to grow and reproduce like a phytoplankton culture. In this case, the symbiosis becomes less advantageous to the coral, and it will expel some of the symbionts to try and re-establish maximal benefit from its algal partners. As a practical note, when very high densities of zooxanthellae exist in coral tissue [because of to much nitrogen], the resultant coloration of the coral is usually a rich or dark brown color.
"Coral mucus, in turn, and as was shown in the previous article, is itself a food source to the reef.
[Skimmer remove mucus, but do not remove nitrogen]

Question:
Anyone know where to buy marine self-priming pumps? Several people are trying to build the top-of-nano scrubber I posted, but in order to put the pump in the scrubber (and thus not in the display), the pump needs to be able to pull water up and out of the display. So far, the only thing found is the Eclipse nano hoods with small pumps built in, and a few other HOB filters with small self-priming pumps built in. But these are built-in and molded to the other parts. What is really needed is a self-contained pump that is separate from the other parts, and which of course is aquarium safe, and in the 70 to 150 gph range (266 to 570 lph).

Look at the 501 ZooMed Turtle Canister Filter.

Will do. It has a pump which can be removed and used separately?
Think of it as a tiny Fluval. It can be keeped out of sight and used to take water from the tank and bring it to the top of the nano where your scrubber is. You just wouldn't use and filter media and use it more as an external pump.
