An aquarium is as close to mimicking the ocean as all those 'naturally' flavored fruit drinks you see at fast food places are to real fruit juice.. you know, the ones that state 'Contains 0% real...

It was just too weak.. I use a full size screen, and 8" away from the screen I still had a 6" spotlight over a 10x13 screen. It barely grew in the spot, nothing on the outside. If I pulled it away...

Nope, the bulbs I got stated they were 660nm/460nm, but when I tested them under a spectrometer the reds were actually 630nm. Still red, but not 'deep red'.

Looks at these 2 links, pretty much the...

That bulb in the first post does NOT work at all. I tried 2 of them for about 6 months trying to make them work.. I ended up putting 2 23w CFLs back in and the screen exploded with growth within...

99% of the liquid tests as well has the Hanna Phosphate meters ONLY test for inorganic phosphates. You can test your water and have it say 0.03 phosphates while at the same moment you are dumping in...

I have a different reason for the placement of my skimmer. I put it after my ATS (which is on my overflow). My reasoning is that algae releases oils, lipids, etc... and all those things are...

That is a different type of phosphate though. Organic phosphates are not the same as inorganic. Organic phosphates are something most people never test for and I don't consider organic phosphate as...

All I ask and have ever asked from you is 'to prove it'. Show us some scientific paper, some personal experiment you video, anything to back up what you are saying. I have shown from a link that what...

Yup, you got it right Floyd. Under high pH, phosphates in the water will form precipitates. When you dose Kalk or the 1st part of 2 part, Alk, it creates a very high pH zone in the area it was dosed...

Have to disagree with you. In this picture I used rock that was fully saturated with N/P when I setup the tank.. half the rock came out of my 10 year old 29G that was a 'rock wall' aquascape for a...

Can anyone show me one valid link to show phosphates have the ability to 'leach from rocks' in a normal saltwater aquarium setting (pH 7.8-8.2)? The only possible way for phosphate to 'leach' from...

cyanoacrylate ... ie 'Super Glue' is safe is it not? I certainly wouldn't use anything that has the gooey glue like the stuff that comes on the back of some velcro in an aquarium though... bad bad...

I can't say with 100% certainty, but I can't find any info on them eating any type of meat. The opposite actually, they require algae to live.



And
...

Of course there are.... they just don't come in fish form. One of the most popular herbivores I can think of off the top of my head is a lettuce nudibranch.

How about some details. ;) What are the CA/Alk readings once it is dissolved in x volume of water? How is it better/worse/cheaper than using Kalkwasser?

Am I the only one thinking the 'green grabber' method is taking a step backwards? I see it as a huge negative, not a positive. Reason being is 3 fold, 1, algae is going to grow more dense, leading to...

I really need to get off my butt and make my new ATS. I am thinking of calling it a Pyramid Scrubber. Basically 3 screens in a chamber, 2 almost vertical but with a slight angle so the top of the...

Sorry, no pics or vids, made it many years ago and ended up giving it to someone else. It was just a larger 'MAME' skimmer like this video shows. Instead of the air pump/stone on a 12oz soda bottle I...

Too bad the pump is epoxied to the bottom of the skimmer. Raising the skimmer up so only the bottom 2-3" is in water along with a stronger needle wheel pump would have made that work, but I am sure...

Anyone else catch why that skimmer wasn't functioning properly in the video? The water level was way to high in the chamber it was in. Same thing would happen to a $1000 skimmer.

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:
http://ccreefs.com/viewtopic.php?f=47&t=124

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.

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...

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...

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...
