I would not say that your tank has overly high nutrients.
SM, you are directly contradicting what you state in your product description page, that the SURF creates a low-nutrient environment...
So it's been well over 2 months now, have you tested your N and P? Instead of looking at the algae and drawing a conclusion about what might be going on, you need to run a test and find out where...
I agree that all quoted posts should really include the link to the actual thread where the statement was made. But the problem then is that it becomes difficult to broadcast-post that across 100+...
SM, I think you need to read the OP again. Ricky wasn't asking for a generic list of testimonials about scrubbers in general, he was asking people to post their specific experience with UASs. You...
I would not have bumped the light up that much that fast, without a base of growth. You're causing photosaturation. I would bump it back down to 8-9 hours/day and let it grow - don't harvest it...
With chaeto or any macro that is grown in a fuge you need to trim it almost daily or every other day in order for it to be truly effective. For chaeto you need to rotate it to avoid shading. So...
Well I think the problem in general with LED PAR type lamps is that the LEDs are too tight together and this causes coverage issues. I haven't played around enough with them but there appears to be...
Or this one, just posted on another thread

except it's made in china of course so there are typos, like "9 pcs 3W" and "6pcs red 660nm+1pcs red 630nm+1pcs blue 460nm". So 6+1+1=9. Hmm. Interesting.
Now that looks like a good lamp
I would remove most of the chaeto but not all of it. Leave enough of the chaeto to do it's work in case there is something else going on that is preventing the scrubber from growing right.
But I...
That is about the most unscientific experiment though. Look at the beginning. He takes cellophane colored filters and puts them over each pod to filter out the other colors of light. That's no...
I didn't say that we use CFLs without phosphors. All fluorescent tube lighting is UV on the interior. The phosphors shift that light into visible light. This is why a UV fluorescent tube is...
LED 2700K is not the same as CFL 2700K. CFLs use phosphors to shift base UV light to visible, so there is a large spectral mixture. LEDs are element based and give out a completely different...
Why would he sell you something that was different than in the pictures. That's just odd.
That looks like it is just plain plastic canvas. It is the right stuff, but it is not roughed up, that's all.
+1 on my blues and whites. Those are too powerful and will just result in a burned...
I completely disagree with the turnover issue. I have multiple clients that will back this up. Increasing flow on a waterfall unit allows you to increase the intensity and/or photoperiod and...
Well even bubbles popping on top of the sump water will spray saltwater up as much as a few feet. It's not just the screen that can cause salt creep
I take it that you don't have something draped over the screen to prevent salt spray?
Did one of those start on fire/burn? Looks like one of the LEDs is actually off
A waterfall scrubber can be dead silent if designed and built right.
That is an older thread but the answers are:
1) no
2) yes
Good. Bump up to 16 hours
Ok. I think based on that, it doesn't sound like a flow issue. Add the second light and extend the photoperiod a little. With those multichips you have to be careful about over exposure, so bump...
a 6" wide screen should have about 200-250 GPH over it. If you pump is in the neighborhood of 800 GPH, and then add in loss (which might be dependent also on return pipe size - the larger the less...
Also going double-sided will help tremendously
So are you really putting 750+ GPH over a 6" wide screen? Is that the actual measure flow? because that's a ton of flow.
A you beat me to it with your post. Just checked out the thread.
Are you having tank issues? N at 10-15 is not horrible, but some corals don't like any nitrate.
I would say increase the...
Let's consider more detail:
1) did you err on your dimensions? 130x150cm is like 50" x 60". Did you mean millimeter? That would be more like 5x6. I'm thinking that is what you meant
2) your...

Well I run an L2 on a tank in a dentist's office which is a 144, packed full of LR and plenty of corals, they feed I think about 2 cubes/day of a DIY food (which is pretty rich stuff) and I clean...
Plus xenia don't grow that fast, so you need a lot of them. And I agree on the nuisance - and they will spread, for sure.
So you feed 2 cubes/day now, or is that what you want to feed?
How...
I guess my questions are:
What is your goal?
What problems are you having?
What are your N and P readings?
...because your tank looks awesome already!!
I don't think that's his tank, that's a stock photo
Note that a scrubber on a system with no fish load (after removal of fish from QT) won't need very much light per day, or else it will likely just turn white.
Can you post a pic of your LED array?
You probably read the 9 hrs/day recommendation from one of my posts somewhere as that is what I recommend starting at.
18x6 screen is 108 sq in, so if you...
correct
"Streamers" is the term I use for when algae grows up into the slot/screen junction and starts to block the flow. Literally, a stream of water shooting sideways. This can cause water to pool up...
+1 this is not a good idea That pipe will blow off under pressure. You want to weld in that slot pipe (use PVC) or have a union type connection.
Yes but for purposes of scrubber light fixture sizing, we use the term 3W. I have mentioned this in other thread that 3W is used basically for marketing purposes so let's not confuse everyone....
Looks good, I would drape the pipe and about the top 1" of the screen with saran wrap to prevent streamers from causing problems
No, you don't want to focus the light - you want it to be as spread out as possible since they are point sources. In addition, some LEDs come with different options like 90, 100, 120 degree "lenses"...
Capped. Otherwise algae will grow into the slot and clog it. Water pressure will force algae not to grow into the slot. For the same reason, this is why you don't put cross-cuts in the slot pipe.
Size. you are at 30 sq in now, just go to 45-60 sq in overall. Whatever width you choose for the flow you have available, divide that into the area to get the other dimension.
10x11 would be a...
Width is a function of available flow or lighting configuration, if you're locked into a specific dimension, one drives the other. Otherwise you can make it whatever you like.
I would use 3/4"...
I'd say the main issues here are 1) the LEDs and 2) flow management.
1) the stunner strips:
- not available with 660nw Deep Red
- 24 LEDs, 6 watts consumed, these are very low power LEDs by...
Neodymium magnets are fine, just get ones big enough and remember they cannot be exposed to water
Cree only makes 630nm Reds. These are not the ones you want, you need 660nm Deep Red.
Holy heat sinks batman!
