Hardware Advice Scwd Device

[dave_gray2077]

I'm just started gather my equipment to make my 100g Reef tank.

Just want to know peoples opinions on the above device. Seems like a good little device to get turbulent water movement in a tank. Without using electricity as well or expensive wave makers.

Thanks

Can a mod move this to the hardware section?

SCWDs are good at creating a wavemaking motion, especially the newer larger ones. They're really best suited for use on a larger tank (like 100g) with a big sump pump or on a closed loop. They're somewhat limited in the whole two-way only thing, but you can come up with creative plumbing solutions for that.

I was going to use a Eheim 1260 pump. On about a 20-30 gallon sump. Does that sound about right?

Tanks is in the planning stages at the moment and i'm scouting for equipment. I have the 100g tank and a v400 skimmer so far.

Next on the shopping list two nano Tunze 6025 pumps. I'm going to do some mods on them to get the flow rate up. Some clever people over on reef central have some interesting mods for them.

You could use the 1260, but that's on the low side for flow. Definitely err on the side of the 30 gallon for the sump, 20 is going to end up being/feeling much too small.

OK.

Thanks for the help

edit to add. what about the Eheim 1262. I intend on having a fuge/DSB in my sump aw well. Will this pump at 3600lph be two powerful and produce to much flow for that sort of setup.

No because by the time you have head loss, you're at ~30% less flow. You will need serious bulkheads on this but it should turn out good (probably 1.5" for drain). The 1262 with its bonus head pressure is probably what you want to work well with the SCWD
