don duncan Posted July 23, 2009 Share Posted July 23, 2009 maybe Im thinking about this tank to much. So I have a 215 brick that I will be setting up. I am trying to explore all options before it is set up. What would you suggest. Closed loop or not. I already have a wavebox and korilla 4 powerheads. The tank is not drilled for a closed loop.

Robb in Austin Posted July 23, 2009 Share Posted July 23, 2009 If you sell all the powerheads/wavebox, will it pay for setting up a closed loop? If not, I'd keep the current goodies. I really like the way a wavebox looks. Quote Link to comment Share on other sites More sharing options...
Gonzobob Posted July 23, 2009 Share Posted July 23, 2009 Just my opinion but I'd do closed loop. I'm doing a wavebox / power head setup on my new 120 but only because it's rimless. Quote Link to comment Share on other sites More sharing options...
johnoburns Posted July 23, 2009 Share Posted July 23, 2009 (edited) Does it need to be drilled for a closed loop? I thought you could make one like this http://www.melevsree...closedloop.html which hangs on the back.

Zarathustra2 Posted July 23, 2009 Share Posted July 23, 2009 I plan on doing a closed loop for my 90 when it gets put together. I like the control and look of it with a canopied tank on the tanks I have seen with them installed. I also want to have the tank kinda split in half with one flow on one side (say around 15-20x) and the other side have about 5-10x. I think doing this with two independent CLMs, each with 4x nozzles pointed at each other for turbulent flow will be the best way. Quote Link to comment Share on other sites More sharing options...
dustint21 Posted July 24, 2009 Share Posted July 24, 2009 Dont do the closed loop! Its not worth it..... You have the wavebox and PH's already. If you drill it may break... It will also cost you more to run the large pump over the equipment you have now. Plumbing is a pain. You WILL have dead spots. Its just not worth it unless you are building something HUGE.

mFrame Posted July 24, 2009 Share Posted July 24, 2009 So you're saying in a 90g don't do a closed loop? The alternative is just multiple power heads? Quote Link to comment Share on other sites More sharing options...
Zarathustra2 Posted July 24, 2009 Share Posted July 24, 2009 You can do it as an over hang situation but reccomended is to have a drilled point in the aquarium. You can also have the pump in your tank using a high end submersable pump.

dustint21 Posted July 25, 2009 Share Posted July 25, 2009 IMO I wouldnt use a CL on a smaller tank. Its just a pain to drill all the hole and taking a chance with thin glass. Also If I were to have a CL I would want to be able to drill the bottom..... Good luck finding a tank without a tempered bottom. A CL is also a pain when it come to aquascaping. If the tank was going to be Large and Inwall I could see using a CL, but on this setup I think you will be happy with the wavebox and a couple powerheads.JMO. Also if you look at alot of CL tanks you will find they are using PH's, wavebox's, and vortechs...... Dustin Quote Link to comment Share on other sites More sharing options...
mhart032 Posted July 25, 2009 Share Posted July 25, 2009 cracking would be my fear.
