I,m not sure if I will. Never did on a Duraso before but if I do a bean style I will. Dont know where they sell them, perhaps MOPS. Also if you look on Rich,s site I posted on your thread, you will see the ones he sells but also very nice looking long strainers for them. I have made many but am going to order two from his site along with the strainers if thats the route I go.

The stacks pictured are only half way up

Bulk Reef Supply is where I got my strainers.

Bean would be nice if you're willing to drill the extra hole. I had read a lot on the Bean, and now that I've used it, I'll never go back to anything else. I ran Durso's on my last reef, but when a plug up occurred I woke up to a sopping wet floor. I like the idea of the emergency drain and back up plan, not to mention how quiet it runs without any salt creep.

Yes, I could drill another hole for sure. Left my drill kit somewhere in Brandon though so need a new one from Dan at MOPS, I guess.

I have to go read on them. If I made a 1.5. in drain pipe, which is around a 2.25in hole for bulkhead, would that be my main drain and the other two back up or why the three drains?

You plan on building an overflow box right?

Anyways if I was you I would, and just run both drains as drains and run a herbie system. I have no clue why people run bean animals I don't understand the concept over a herbie system. I have a durso right now and its a PITA.

I guess if you were to go with 3 holes in your overflow and drill another I would add the 3rd as a return. I would drill the 3rd hole to be bigger then the other 2 and use the bigger of the 3 as the emergency drain.

Yes Im building an overflow box. I already have 12mm glass cut for it. Forgot one thing on drilling. I believe its all tempered, so no go on 3rd hole me thinks.

So if going herbie, then my main drain would only be 3/4in. below the tank and to the sump. I suppose ok, if I dont push a lot of water.

What sort of problems are you having with your durso? I've been using them for 5 years on a few different tanks and have never experienced a single issue with them. Plumb it in, drill an air hole on top and you're done.

Thats what I thought. Never had a problem either and been using them since Rich first showed us on RC. I figure with two I wont have an issue with plugging up.

Of course if the flow exceeds one of the stacks and one plugs then still overflow right. Soooooooooo, if I have to keep flow at a capacity max of one duraso, then may as well do herbie........:lol:...Im going to pour a vodka

Because there isn't constant adjustments like with the herbie. If my intake strainer on my pump starts plugging up with bits of chaeto and detritus, and my pump starts moving a little bit less water, the Bean self corrects for the change in water. If one of the drains gets partially plugged with a snail, or dead fish, or sheet of Nori … or any other number of things that can potentially plug a standpipe, the bean auto adjusts and allows the second drain to become full siphon, plus there is still an emergency drain in the event that both manage to plug. Not to mention, in the event of a power outage, my system starts right back up with zero fiddling around or adjusting, and runs dead silent with no salt creep.

They need to be adjusted, salt creep can cover your air hole, they're noisy, air goes into your sump causing a ton of salt creep as the air dissipates, and there is no back up in case something plugs the drain.

Vodka solves all tank problems!

Not sure how I would ever adjust a durso, a piece of hose in the air hole prevents salt creep, never had a noise issue, my drain went into the sump water with a tee and a 90 above the water to exhaust the air so very little air went into the sump so no salt creep (probably also what made it so quiet), I still had an emergency drain for peace of mind on each system but never needed it.
