I think I overdid it with a Stream!

[pjr]

I was pleased to find that my Stream 6060 had arrived while gone for a short trip. I hooked it up last night and was blown away by the performance of this product! First class stuff!

However, I think I may have overdid it... seems that it's a bit too much for my tank and the inhabitants ara a bit overblown as well. My tank is a 5' reef and the Stream is mounted on one of the trapezoid-shaped overflows. The tank does not have a lot of rock structure... wanted room for the fish too! The soft corals at the opposite end of the tank are getting totally whipped -- not an expected result.

Any advice? I know, I should have purchased a 7210...

Interesting how much the flow depends on the reef structure. I have lots of rocks in an 82 tank and I got the Stream 6100 oscillating between mac blast and min in 3 sec. intervalls. I also have an 7300 oscillating. My soft corals are just nicely swaying. Ok, perhaps one acro frag is getting to much it's placed right in the jet-beam. We'll see.

pjr, I have my 6110 mounted on the overflow of my 6' tank along the back glass. At first I had to point it slightly towards the back glass (rebound effect) because the flow was to great for some of the corals (and sand) in a direct line.

You will have to try some different flow directions, and placement. It really should not be too much. Bear in mind that in my opinion the flow we are used to in our aquariums is all wrong, anyone who has been to the sea will tell you the force of the water will toss you around, the corals are used to more flow in the wild than we provide in our aquariums, in addition this flow is of the wrong type- narrow jets. Their are several ways to remedy this but try different angles and positions first, also give the corals sometime to adjust. Rock does have a great impact though.

I've had a stream 6060 hooked up on my 72 for a few days and it's definitely not an out of control flow IMO. Actually I have it running in conjuction with 2 sea-swirls (one hooked to a Mag 9.5 and the other to an Ehiem 1262) and I finally have about what I was looking for flow wise. Tunze if you are listening :thumbsup:
pjr give it some time and I think you and your corals will be happy in the end run.

I've got a pair of 6080's in 30" X 30" cube tank, quite impressive flow. Although I might be considering adding a pair of the 6000's with a multicontroller to them. Looking for some really serious water movement, I think.

No substrate, no fishes. But really happy sps corals.

I just finished re-installing the 6060, this time in a different loction. The leathers are now behind the Tunze, so they get flow only after its returned from the other side of the tank. Still lots of current, but not trashing them as before. The LPS aren't the happiest, esp'ly the Bubble coral that's been thriving. I moved him, we'll see how he does.

The tank has more noise now... it's the Tunze waves bouncing at the top of the tank! I just can't believe how much flow comes from this small pump. Anyhow, we're going to try it a few more days.

Pjr, placement is the whole key. I have mine attached to my AGA overflow pointing directly across the length of the tank (4'). The flow hits the far side and bounces back across the entire reef. When I first had it set up it was drifting sand but I now have it positioned so that sand drift is manageable. You're right I can't get over how much flow these things put out. I've got a mixed tank of leathers, Xenia, LPS, and SPS and everything is responding well. Obviously you don't want to blast anything too much so try different placements until you get one that works. My fish absolutely love the current. I would give it some time before bailing. If it can work in my 72g it can work in your 100g IMO.

Even then, before you give up send me a PM, we can discuss some other options of last resort.

Thanks Roger! I'll keep you posted.

One question: I've put the unit on a timer. Is there a maximum number of times the 6060 can be shut on and off in a 24 hour period? I remember duration (it should be at least one hour intervals), just don't recall if there is a frequency limit.

24 times a day once every hour.
