To Make Waves or Not?

KMP · 09-19-2006, 02:09 AM

Just hooked up my third MJ900. One has constant power and rotates a Hydor-flow. The other two are plugged into a Natual Wavemaker and currently set to alternate every 50 seconds. Just wanted to hear from the pros on which is best regarding the two pumps on the timer - wave movement by having the two on a wavemaker or having all three running at the same time for increased flow.

I have a 24g Aquapod so whether the water flows from front to rear or side to side would be the same. Stock it had 295gph flow, with two MJ900s it has 460gph, if all three were running it would have 690gph (minus reduced flow rate for bends of course).

I would estimate that the increased waterflow from front to rear would do more harm than good. Sounds like your MJ's are more than capable of handling your 24G aquapod current needs. Sometimes more is not better. I suggest kiling the hydor and sticking with the Wavemaker on 50 Sec intervals. By the way...Get rid of then dang damsels!

^ I talk to you day in and day out about this stuff and you never have anything to say. Then I get the dang pump, hook it up, and you have an opinion

Yes, I need to get rid of the Damsels you talked me into as "bait fish" to test my water. No, I will not flush them. And while we're at it - take the poll!

At IMAC at one of the presentations about flow, it is best to have a circular motion of the water like right cirlce than reverse the flow to left circular.. I have no idea how to accomplish that, lol... But you could go like 3 minute intervals in each direction...

It is also a good idea to have flow at the top of the water to create oxygen exchange. I dont know if "waves" are actually needed all the time..

You got a huge amount of flow for that size tank..

i prefer side to side cross waving.

Kensn · 09-20-2006, 02:07 PM

I think an alternating flow would keep you from having dead spots in the tank and keep debris in the water column to be skimmed or filtered out. As far as what type of alternating flow..... I don't know...

KMP · 09-20-2006, 11:59 PM

thanks for everyones input - except for 12gDude

i had a closed loop going around the top of my tank with two outlets in either corner pointing to the rear of the tank. i began thinking about water direction when i noticed one front corner seemed as if it were not getting much flow. my intent was to add another pump and have it running continuous. however, since i hand the natural wave maker powerstrip i was able to have the pumps alternate - front f/50 sec and then rear f/50 sec. now i can see the frogspawn in the once dormant corner swaying as the the outlets in the rear are pushing water towards the front of the tank.

i agree, side to side would be best, but in my case front to rear and side to side is the same since it's only a 24g tank (Aquapod).

such a small tank,,,hard to do

Out of curisosity what was the presenters basis for the circular flow vs right to left or up to down or any other direction for that matter?

I do agree that it is very important to have turbulant water up top to increase gas exchange. In addition to making the halides look "purdy."

quick update.

i still have the pumps on a timer so the water circulation goes towards the front for 50 seconds and then to the back for 50 secs. so of the 3 pumps; 1 is constant and the other 2 alternate which accounts for 460gph flow.

my pom-pom xenia is more upright than before, the sun coral is out more frequently, and the frog spawn is fuller than before.

regardless of the science behind it; the change in water circulation has been a benefit for all inhabitants.

till the new tunze nanostreams hit the market

Charlie97L · 09-22-2006, 03:18 PM

do we have specs on those yet?

are they controllable?

KMP · 09-22-2006, 07:43 PM

any links?

boozeman · 09-22-2006, 08:43 PM

did someone say link?
