I appreciate it. Do you have my shipping info still?

Howdy,

Lov'n the S2 - harvests have been light; there are boatloads of 'pods' in there munching away most of the algae growing on the surface even though I'm fresh water spraying. It's still doing...

Yes, regardless of flow rate PO4 and NO2 will uptake at roughly the same rate as 100gph.

Your checker may be faulty, however, there isn't a baseline for uptake due to so many designs etc.. I wish...

Intensity of light seems to be more effective than time of light exposure, i.e., my 400 watt MH at 4 hrs can grow what T5s at 12 hr cannot.

As for P04, the sooner it's gone the better. Nothing...

Ahh to be new to scrubbing...

There have been at least one test using commercial fertilizer and an ATS to determine the amounts of each, PO4, NO2 that were consumed. I don't think the experiment...

It's been a few...years since I've been actively following the scrubber anomaly. I just picked up a "Surf 2" (Which is growing very nice and green on its second week plugged in; nice work SM!)....

I've been a busy lil beaver over the last year and have been incognito to say the least.

I know this was a debate, and hope no one gets butt-hurt bringing it up again. Anyway, what I recall...

I ordered some "pink" LEDs from aquastyleonline.com as well as Royal Blue, and near UV (380-420nm). Also, some more 660nm deep red.

I hesitated knowing that these would be "Chinease" LEDs, but at...

If dosing Cal Chloride and Sodium Bi/Carbonate an occasional water change will be nescessary. Depending of course on you're usage. More frequently if you dose Epsom salt - Mag sulfate.

If using...

Took me a couple cycles to grow the funky green stuff. I imagine any existing algae would compete with the green variant. Scraped mine real close to the screen to rid as much of the crappy brown...

I get a very strong feeding response with PE Mysis whole cubes. Some corals, milli's especially, are all fuzzy and crazy. I need to get a pick of it...

I agree 100% about being nitrate limited,...

Ran into the same issue. I did a 30% WC to reset dKH, it was around 14 and Ca at 380. I suspect the dolomite as the culprit. Since Mag is such a light ion (even at NSW lvls ~1200ppm it makes up a...

I don't care for BRS for the tediousness of daily dosing, and dosing pumps cost the same as a Ca reactor. I do it like that I know exactly what I'm putting in my tank though.

B-Ionic OTOH can...

Bulk Reef Supply is the cheapest source of Ca and Mag, for Carbonate it's cheaper to buy Arm&Hammer from the Grocery store (and better quality - food grade). Water changes must be performed when...

Hydrogen Peroxide dosing has shown to be effective on dino outbreaks. It will also kill sponges and "pods" so buyer beware.

My short list:
Zero light leak
Plug and play plumbing fittings (unions?)
Quiet
Zero micro bubbles
Quick release/easy clean screen
Mounting options (brackets etc.)
Full LED integration
Print...

Link is dead.

Distance from screen has to be factored in as well. I am currently @ ~3" distance. We should start a thread about this to pool user experience and best practices, e.g. what works and doesn't.

As Kerry said. You'll want 630-660 NM Red/Deep Red LEDs.

I personally use ten 660 NM Osram brand LEDs on one side and 100 watts CFL @ 2300K on the other. It's not even a fair comparison. The LEDs...

Use Kalk to top off, and correct with BRS. As for calculating you'll have to see what others are doing for an approximation then tailor the dosage to your needs. Kinda wish I had a separate ATO tank...

I added quite a bit of EC'ing to my nano tank that I plumbed into my 120. Things got very bad in both tanks. Huge dino bloom on the EC, and algae bloom in DT.

I'm certain there are silicates and...

Take the rock and flip it upside down - lit side down, dark side up. It's not the prettiest method, but it sure as hell worked for my bryopsis issue. Basically, same thing as light out without F'ing...

That looks like fun...gia! Hah!

Related: I don't think light is the issue, but I will prove it either way.

I just replaced two 400w Radiums bulbs at one yr old. Big difference. If light is the culprit I have now taken it out as a limiting factor in my system. I will report back in a month if my brown...

The short answer is yes.

They will not interfere with a scubber much. Ca reactors, depending on the media used, can add Phosphate; which would fuel growth. Kalwasser has been shown to precipitate...

I'm pushing about 700-800 + GPH over a 9" screen.

I just got my LEDs set up and was toying with th notion of running them without a diffuser.

However, I have to keep fixing bad solder joints....

So we should crop our algae crop? Haha.

I don't see the relevance of the title to the quoted material. Or to Scrubbing.

Interesting to know the metric used to calculate human contamination of...

Used the multimeter and found the bad solder joint pretty fast. A lot of rosin on the pad. Thanks for the help!

I purchased 10 Osram 660 LEDs from rapid, as well as an LPC-35-700 driver.

Soldered and mounted everything on heatsink. Wired the driver in an electrical Junction box (waterproof).

Had it...

Your scrubber looks great. Give it a few months to really mature. The slime will relent to a form of solid algae once you get your lvls down.

So I finally invested in a Hannah Phosphate Checker. Got it today. And after some time I got a stable reading of .07 PPM Phophate.

According to:...

I can just plug the "clean" one in and get it going. Take my time on the one needing cleaning.

I assume the "stored" one would grow in faster too, since algae would begin to grow a lil in that...

Has anyone tried running ozone in a scrubber only tank?

I would love a non carbon option. It's an expensive hassle replacing it weekly.

Also, my SPS aren't nearly as bright they are for the...

It'd be a "cleaned" screen. flow would be off the scrubber box, and light spill from the box as well.

I'm gonna give it a shot. Not happy with my screen's roughness anyway.

Instead of jacking Floyd's disgusting thread :mrgreen:

Live rock is not alive, but houses a variety of life. Base rock is live rock that is devoid of life.

Live rock serves a many fold role...

Sorry as well Floyd.

As for surface area: It depends on a few factors. Grain size of sand, and porosity of LR. I'll use my system as an example of how LR has more surface area.

I have medium...

I don't know any reefers that syphon their sand. What would the point be?
Also, why would you want to clean a rock? I hear of people using a turkey baster to "blow" off their rocks. Seems pretty...

Had a thought I'd like to run by you guys.

What is the consensus on running two screens. One lives in the fuge, the other on the scrubber. When cleaning time comes pop out the full screen and...

Found a small white "egg shaped" thing stuck in my overflow grate. You never know what's going to turn up in a reef tank. Curiously, I fished it out with the aim to dissect it.

Laid it out on a...

What are the LED specs if you don't mind?

I'm building pretty much the same thing. My plan for light diffusion is sandwiching two acrylic fluorescent light diffusers together with a drop or two of Weld-On.

Same boat here, same lighting, same great growth, good PE on everything but my Millipora and 4 Acro colonies. Same Acros are a lovely shade of brown.
They were coloring up with the addition of GAC,...

Just ordered their ~9x~8" for 20$...

Will let ya know what I think when it gets here.

Sulphate is only part of the issue, and a small one at that. Magnesium Sulphate is not dosed nearly as often as Ca, or Carbonate, as such Sulphate's percentage of total solution is low, and may even...

Sorry, screen width is correct.

You're looking at it from the wrong angle. Think of it in terms of how much food you want/need to feed, then calculate your needed screen size then multiply by 35. Simple, right?

I find this reading interesting as I am scared of pressurized tanks in my living room. Its a very good option if your tank is not very big. (and even if it is big :mrgreen: ) ...

It's no different in that sense. Again, it comes down to the ratios of ions to each other. Nothing consumes Chloride/Sodium in aquaria. It's an easy way to think of if you pretend you're just adding...

Invented by Stanley, It's a unit of measurement based off of a semi-annual award given to a group of players who hockey the hardest against other hockers.

How do you figure the Kent Liquid CA reactor stuff is the cheapest? $34.99 for a 64oz container vs $11.99 for a 4.5 POUND jar of BRS Kalkwasser (that will last YEARS! Believe me, I bought one, 5...
