Ummm, I don't have to worry about sand with my wave maker. ;)

Old video/bad quality but you can see the wave.

I have tried both of them. The second one in the video in the first post looks like a chinese knock off of the 'Hydor Flo'.

From my experience, unless you do bare bottom, they don't work. 1 grain...

Great design cdm2012! Only issue I see which you already mentioned, is using it with an ATO on the system.

To answer the 3 questions in the OP.

1. Produces less skimmate
2. Produces darker and much stinkier skimmate
3. More temperamental, as it can go weeks and not skim more than 1/2" in the cup and...

Looks like a major disaster in the making if you ask me. Using silicone to bond acrylic, DIY bulkheads, china driver and LEDs, using optics, and using the wrong epoxy (Loctite, which doesn't allow...

Just turn them in to Fish and Wildlife. I would in a second if I knew of something like that going on. That type of blatant illegal activity gives everyone/entire hobby a bad name and gives fuel to...

As long as those readings are stable I would not worry about them at all. They are perfectly acceptable IMO.

Since this seems to be a chart posting thread I thought this was an informative one. ;)

Once you learn how zoothanthellae grows (nutrient and lighting requirements) the answer becomes crystal clear to the 'browning' issue.

Bottom line, if you have brown corals that look healthy...

I got one when they first came out. ;)

My review here:

I think a 'simple' method for making a horizontal that works decent would be to put 2 small powerheads on each end of the tray and use something like a Hydor controller so the powerheads pulse back...

Tebo, I would HIGHLY recommend you moving that computer power supply away from the water. They are not sealed and will pull it humid salt air easily. That picture scares the crap out of me. I don't...

Around the house, yes, I would use them everywhere. On an aquarium setting, no, can't think of a good use for them.

Million dollar question, I wish I had the answer. I know the deep sand bed in that tank is one of the factors causing my issues. I have tried numerous things to resolve the issue (taking out...

Looks like some scientist finally cracked the age old question of why do xenia corals pulse?

I was using dual 42w CFLs, cost $10ea at the time, so it got very expensive replacing every 3 months. The LEDs I use take 28w vs 84w in CFL, so that is exactly 1/3 the wattage and I get much better...

Update. Moved all of them into 1 tank once they got old enough to not kill each other.. then dummy me thought they were strong enough to handle a small powerhead and woke up the next morning to half...

You want just the screen or weekly harvest from the entire system? LOL. I just pulled out at least 2x as much out of my display compared to what I just cleaned off my screen. I don't have a scale to...

I don't think it is really even debatable comparing a surge system vs a constant laminar system. A washing machine comes to mind... take a dirty piece of clothing and hang it then dump water down it...

A couple good scenes in that documentary above. Garf, what are your thoughts on the 'freshwater on algal cells demo' they showed. I wonder if/how that translates into how we clean our screens.

For...

Honestly I think that has to do with better husbandry all around. In the 80's, it was crushed coral, lava rock, and undergravel filters with little water changes, and when water changes happened it...

You're welcome again. ;) http://www.bbc.co.uk/programmes/b01rtdr4

As always, I appreciate all the research and sharing you do. :)

My thoughts on your last post... I wonder how much bacteria is contributing to the organic P uptake. Since there is a symbiosis...

I would not attempt to regenerate aluminum based phosphate remover (Phosguard).

Seems putting a plastic cover directly on to the algae mat on an ATS, like the picture shows, would inhibit gas exchange? I understand what you are trying to do, I just don't think that is going to...

If you are using a dedicated pump you can just place the effluent of the reactor right next to the intake on the pump. If it is from your overflow, then drilling a small hole in the top of the slot...

Hmmm.. thought of this many years ago when I built my first ATS, which was double screens (at the time was recommended). I decided against the idea and instead split my overflow into 2 separate...

You're welcome. ;)

Thanks for confirming it Floyd. Always good to have multiple people try things to confirm or deny results.

Here are 2 vids that speak for themselves. If there was any type of oil or wax I should...

Couple observations just going off the video. The algae doesn't seem that strong judging by how easy you were able to scrape it off. I literally have to sit there and scrape hard over the same spot...

Well after seeing SM's new signature banner, it all makes sense now. Still bollocks though about the screens.

After hours of searching and asking around, I can't find anything about wax being used in the Mfg process of the screens we use. As a test, I have a few sheets of brand new screen laying around. I...

I wonder that as well as my Koralia power cords that are in my sump are always covered with hair algae, more than anything else in the sump, so I think there is some validity to your question.

Great article! Not sure how much it helps our needs, but I am also a huge bio-fuel/algae supporter and this seems like a huge advancement for that field. Thanks for sharing.

Just to give you a little piece of mind, I run 14 LEDs off one of those drivers, 6 reds (OSRAM 660nm) + 1 blue (Cree Royal Blue) per side. It has worked perfect from day 1 for me.

One thing I...

Are you living in Syria today? If you are, you would have to be one of the most dedicated aquarist on the planet due to what is happening in your country.

To answer your question, you can use...

Ummm?? http://www.coralrestoration.org/

Thanks to humans, the Staghorn acro, which was nearly wiped out by nature (massive sea urchin disease/die off was one major factor), that coral is now on...

Just ran across this product on RB, Aqua-Crobes. If it works, this is the type of product I was hoping for as we learn more about the microscopic processes in a reef tank. Step 1, figuring out a...

Day 6 is still rotifers.. day 7 I start to add a tiny pinch of OTO-A, and ween them off rotifers between day 7-14. Usually days 12-14 is when they go through meta, get their color and head stripe...

You also have to take into account even with all the work, and finding a Kiln to cook the carbon in afterwards (a critical step from what I have read other places), you get an extra 10-25% more use...

Citation needed?

Carbon (and Purigen) works via the pores that trap the stuff you want to remove from the tank, it is a mechanical process. The only thing kneading it will do is 1. Break up the...

Only thing I know of that works similar to carbon that works in SW is Purigen. Chemi-Pure contains 'ionic resins' and it has been proven to be a joke in SW. Just google it. ;) From what I remember,...

This diagram shows why the CW/RB combo lacks bacteria.. that combo of lighting lacks the spectrum under 450nm and above 630nm, which as you can see is where bacteria colonize the most around algal...

Good call rleahaines. I had that problem happen to me once as well... city dumped a TON of chlorine into the water to sanitize it (so much it smelled like a swimming pool when you turned on the...

I believe the tests above are similar to the tests used in this article. I just want to be able to take 1ml of water and culture the slide to give me an idea on bacteria count in my tanks.

I have had a feeling for a number of years that a key piece of the puzzle missing for us hobbyist is the ability to test bacteria levels in our tanks. There have been plenty of studies showing that...

I have noticed this as well on one of my systems.. the screen grows very well, but also catches a TON of detritus. So much than when I wait a week and take the screen out to clean the first minute of...

The only time I have had a screen turn to mush and crash my tank was when I tried to use Biopellets in a BRS reactor.

With cyano, isn't there a special ratio of N/P that encourages growth while...
