Questions about flow

[Okguy]

Check out some of this guys builds. He has some very cool ideas on hiding CLs and power heads.

you can also use something like this

just remember that the power cord will probably be visible when it leaves the tank.

Those fake rock ph covers look great. Any ideas on how to hide the cord?

I think another issue with a closed loop system compared to ph’s is the way the flow is distributed into the tank. Ph’s provide you with Tubular flow as apposed to a pump that will only provide you with laminar flow (flow in different directions apposed to straight flow). The flow that comes out of a ph will be way more comparable to the flow in the ocean. Not as big of an issue in a softy/lps tank but sill beneficial and will spread the flow way better in the tank. If I were you I would just buy a Vortech ph. That will give you enough flow combined with your return pumps, not have a cord in the tank and sill supply you with nice water movement, then if you decide to go towards an sps tank which is a likely step you will have the added benefit of a great ph. Plus cost wise, it would be comparable if not less then to drilling your tank plumbing the closed loop and adding a pump, not to mention way more power efficient.
That’s what I would recommend.
Check out the Vortech ph.

If i were going to go with a closed loop system I would look at the Red Dragon II with the ocean simulator. Or at least a variable speed pump then you can do more with it.

OK....just my 2 cents here...

Nobody has yet to mention the safety issue of having ph's placed in the tank. Can be a "shocking" situation if something faults and you do not have the right protection in place (GFI outlet for example).

I am a "purist" as well when it comes to tank appearance. I would rather go with a cl and a sump than have a single ph or heater in my display tank (which is the way I am planning my 90 g).

As for current...does anyone here run a SCWD cl? Is it worth it?

What is SCWD?

I agree with you: normal powerheads take up a lot of tank realestate. But I like my new vortech. I wanted a clean look in my tiny 45g tank and a single vortech did the job. If you ran one on each side it would look cleaner than the pipes sticking out from a closed loop and then you could have wavy looking action that'll make the polyps of your LPS and softies look cool.

It's hard to directly flow from a closed loop unless you start using locline and then you're starting to get clutter in the tank again. Vortechs pretty much don't need to be pointed.
