I still have to take the time to read the full article. I did a cursory scan and then posted it up. The MJ 1200 may very well be their new propeller pump, Jonathan. They released a new pump earlier this year that can be used like the regular MJ 1200 or like a propellar pump. Everything comes in one box. You can google it.

In the real world, not very but we all know that you "need" 20-40x turnover so the numbers are at least useful and now we can say X brand will need 2 powerheads to accomplish the goal.

It was probably a matter of just trying to get raw numbers. I would think that flow at 1 ft or 2 ft out would be so random that measurements would be unrepeatable. Also that far away you start running into aquascaping in a real tank which really affects flow.

hmmmm....I wonder how important that really is for hobbyists? I suppose to get accurate results across a spectrum of designs, that's a fair comparisson, but I would be more interested in flow/cu in. @ 1ft and 2ft. The article and study are amazing to be sure, and in no way am I trying to detract from that great work. Just curious about the measurement. I sure would like to see a Maxi-Jet 1200 mod in there too, but I am sure moded pumps would be DQ'd for all sorts of reasons.

Thanks for sharing Marc.

I'm a bit surprised by the Tunze's and Koralia's results.

Jnarowe; presumably, the distance the measuring device was placed downstream from the front; equal to the diameter of the pump face, i.e. if the pump face is 2 inches in diameter the measuring device was 2 inches away.

Awesome! So what does that mean, "distance of one diameter downstream"?

My next talk is this weekend in Little Rock, Arkansas. Thereafter, it'll be in Des Moines for MACNA. Charlotte hasn't asked me yet.

Marc, when you coming to Charlotte for a talk.

Hopefully I will be able to attend one of these meetings soon, I always seem to be out of town when happen. Will be picking up RO/DI system from you soon Marc.

So I have done that, and ultimately pulled the rock out of the remote tank. The issue was that the RT was a huge detritus trap. I suppose that suspending the live rock above the tank bottom and improviing circulation would have worked too, but I didn't think of that at the time.

Moon lighting sweet,seems to be a perfect shade for some romance! Maybe info best kept to your self.LOL

Yes a more open look gives the fish more room, has long has they feel they can hide if needed they will have less stress so less disease.Every one wins,I do feel live rock is a huge plus. The best of both worlds would be a open aqua-scape in the DT and lots of live rock in a remote tank tied into the DT system. IMHO

I know that montipora like higher magnesium, and I usually shoot for 1400 ppm. I don't dose it, and haven't dosed once since I set up this tank. It's already high in the Sybon Salt, and then my calcium reactor media has some magnesium within it as well.

great photography! i like the abundance of fishes. something i could never keep up with LOL . must take a lot of feedings?

Is there a downfall to having your mag that high? I kept mine up there for a few months to get rid of bryopsis and everything did great except the bryopsis.

Not sure I would say that Marc. Tanks like your 280 and BrDs tank are very similar because of the maturity of the tank. I will say I love the look of a tank that is loaded with fish.

I don't vacuum it, but I do take a credit card and work my way across the front to clean the area between the glass and sand every 60 days.

This guy's is much nicer than mine. It's quite a bit bigger too, I bet. There weren't any facts associated with it, in the description.

I have no idea. Maybe it was up on the rockwork and one leg ventured into the opening where the prop spins, and it got snagged that way.

It's beautiful! Made me think of marc's 280 and your tank brad.

Have you done any vacuuming of the sandbed yet? I think I waited about a year before I did. But now I try to vacuum at least the front part once a month or so. I hate the ugly look of the algea against the glass. Just my opinion though.
