Using SCWD's

[J McCauley]

Hello all!!! New to SW and to this forum......I have started to build a 125 system and planned on using a closed loop system for water movement. I have read where the SCWD would handle 1400 gph and will purchase an Iwaki with Japanese motor with this out put. Has any one had any dealings doing something like this. I have read old posts on subject but nothing new as of late. Concerned that the fast swithcing of the SCWD will not have the impact that I am looking for.

Thanks

The larger the volume of water you put through the SCWD the faster it will switch.

Welcome to Reef Frontiers!!

Depending on your budget there are other options available. Sea Swirls are pretty cool and provide a sweeping motion, Here are a couple of others:

Motorized Ball Valve

Oceans Motions...Have you all seen this thing?

I have SCWD. And I recommend it if you have a small tank like mine which is 25g. Also if you have several SCWD on your tanks, then go ahead. At least 1 SCWD per 24 inch lenght of tank.

Why? Like you said, the speed between two outlets are really fast. Mere 8 seconds on my 500g/hour pump.

Or, if you want, you can use it by pointing it directly to the corals, then you dont have to worry about the fast transition.

Like Nikki said, I think Sea Swirl is very nice addition.

But if you already have extra submersible pumps, then just add a wavemaker device like the "wavemaster pro" or the "natural wave" for a cheaper alternative.

That motion item looks like something I could go for!! Do you know of any actual users of it yet? Concern is for sediment build up bringing it to a stand still.

I have currently put in three .75 bulk heads for retun but I can easily find room for one more and get the 4 out put model.

One buk head is coming off the bottom to enable me to put a line in at the bottom of the base rock the other two are coming in at the back of the tank near the top.
