Billy be very careful with those new lumenmax elites, people are reporting they put out a ton of light a lot more then the regular lumenmax and some have even bleached their corals.

Also is that the Large cone skimmer or the new medium?

Looks like a really nice job! Can't wait to see it in person!

Thank you for the heads up. I will start with the pendants high and slowly move them down. They do seem to put off a tom of light and it looks like they spread it very well.

The skimmer is John's large.
 
On a Dart they will restrict the flow of the pump if only using 2. The oulet on each eductor is only like 1/2".

I know that. I'll see if I can find the article, but according to my research an increase in head pressure (restricting the pump) will make the eductor more effective, the ones I was looking at work the best at 10 psi IIRC. I'll try to find the article. It may not matter if you are using a different type of eductor though.
 
:thumbsup: looks like it is working fairly good for the load.

Picture time.

I keep becoming more and more amazed by these cone skimmers. I started it when i got home today and here are pics with it only for 1 hour with just the dry rock in the tank. I cant wait to see it perform when the tank is stocked.

Looking real good Billy. I wish my house was layed out in a way to do a cool setup like that.

Thank you. It really worked out to be a perfect spot.

OK, I found it.

That is why I am curious, if more head pressure would result in more flow in the tank even thought you are returning less water, or if you get more overall flow using 4. I'm planning out a system for my own that will be around a 360gal tank and was looking at the eductors/penductors to increase flow without adding more pumps.

I read that when i was researching the eductors myself. I understand what you are saying about the more pressure to each eductor increasing total flow. I decided to go with 4 because after reading that info and looking at the Darts flow chart i didnt want to restrict the pump because it quickly loses flow through the pump with increased head pressure. They shutoff at 12' head which is equal to 5.2 psi. This is my first time using the eductors and i didnt really know what to expect from them. I was trying to get any extra flow i could with the Dart i had so i could try to stay away from powerheads.

I think if you want to try to get the most out of the eductor i would go with a pressure rated pump like the Iwaki's.

Thanks for the answer. From what I've seen going to a pressure rated pump raises the wattage so much that it seems counterproductive compared to a Tunze Stream or a Vortech pump. Same reason I've been leaning away from a closed loop, I think you could get more flow for less watts that way.

Do you have anyway to estimate the flow you are getting? Tank looks great BTW!:cool:
 
I agree. If you dont mind the look of the Tunzes or vortechs then that is the best route to go. You cant beat the flow you get from them for the wattage. I will probably end up with 1 or 2 powerheads eventually. For now i am going to see how 2 waveboxes and the returns do. I never liked the closed loop system because of the power to flow ratio.

Going by the flow chart on the dart the pump should be pushing about 2000 gph. For how much extra flow i am getting i couldnt say. If you are ever in the St. Pete area let me know and you are more than welcome to come by and see them in person.
 
Unfortunately i had a little set back. Either my stand itself settled or the tile under the stand settled and it caused the the bottom panel to crack.

Marineland has stepped up and they are replacing the entire tank. I am also having a steel stand built and taking up all the tile that is under the tank area. The old tank should be moved out saturday, i should have the stand sometime next week, and i should have the new tank within the next couple weeks.

I would just like to say Marineland is a top notch company. They didnt have to replace the tank but are doing so anyway.
