Drop off reef design - Starphire

I might also go with a matrix of gyres, but I don't know if the flow would be sufficient or if the inlet/outlet design would align with the use of an acrylic separator.

just seen those pumps at fishstreet... nice copy^^

I need to optimize the flow/$ again. It's a lot of flow and a lot of $. These are $130 with 4500gph. The WP-60 is $63 for 5300gph. No idea if the pressure ratings match.

That's a lot of $$$ alone in flow...

 

[karimwassef]

72 recirculating pumps... But I'm hoping to get a deal since I don't need the controllers (I'll be doing that with Arduino) - or the power supplies (I'll take care of that too). I hope I can get the WP-60s for $30 for the pump only. That's $2160 in just pumps.

There are Expensive Pumps that cost that much for just ONE pump.

Wow! The pump budget matches a lot of people's total reef budget! Sweet!

LOL
Here are the pumps I wish I could afford

Tunze 6580 ...

One pump would be enough for a quadrant, but I'd need to make the flow uniform.

So. My pump budget = your whole reef budget = half the price of one of these pumps

Start a gofundme! :lol:

For a Tunze? That costs more than the car I drove in college.

18 distributed pumps actually give me a better distribution of flow. Any feedback on the design?

A woman started one after she spent all her families money on the powerball ticket!!! :lol:

I think 18 pumps will provide better distribution, however I think the Tunze will still do a pretty great job

18 pumps per quadrant = 72 pumps total. If three quadrants are turned on at 100% at the same time, that 3 x 18 x 5000 gph = 270,000 gph being pulled into the fourth "intake" quadrant. That's why I call it a "storm"

I would never actually do that for more than a few seconds, and I would ramp it slowly to give the water enough time to build to that kind of momentum.

It's good that the design is fully circulating so it's all contained in a closed loop inside the tank. Otherwise, most of the water in the tank could be blasted out of it.

But in this configuration, the only way water can be pumped out is it is first drawn in my the pumps through the back.. and that water must come from the "intake" quadrant... there's nowhere else for the water to come.

Still, when experimenting, I'll have to develop a lid - just to see what's possible.
