Certainly, that's what algae do. But the devil is in the details Thanks for those. You might think more is better, but there are other factors...

With more people wanting to use natural filtration for their tanks, we are going to look at the two main types of units that you can put on your system: Chaeto reactors (or "algae reactors") and algae turf scrubbers (ATS). We won’t be looking at refugiums however, since those have mostly a different purpose. This will be a multi-part post; the next post will start with the basics, so if you’d like anything in particular to be covered, let us know.

There are some actual product pics now... www.WavyFilter.com Here is ours:

Been a few years for me, and I want to see if anything is new or changed.

The pink/copper color is my fav.

Too hard to see. Next time put it on a white piece of paper so the water will drain off.

Might be coral polyps that planted themselves there.

It might go away, once the coral gets healthy.

Looks tasty

I think your local aquarium supply stores or websites will have similar floats.

You can always cool with a fan pointed at the water.

Is that a black gravel?

Did it work?

Still should clean inside with alcohol, and vinegar.

You could just cut up some floor tiles.

How does it feel being the center or the SG reefing universe

I think it shows however that reefs can adapt, and may be able to survive big changes.

It's good to realize that the food you feed has very large amounts of nutrients N and P. So when you feed, you are resetting the N and P ratio. Therefore, usually, there is no need to focus on the ratio.

Nutrient Export What do all algae (and cyano too) need to survive? Nutrients. What are nutrients? Ammonia/ammonium, nitrite, nitrate, phosphate and urea are the major ones. Which ones cause most of the algae in your tank? These same ones. Why can't you just remove these nutrients and eliminate all the algae in your tank? Because these nutrients are the result of the animals you keep. So how do your animals "make" these nutrients? Well a large part the nutrients comes from pee (urea). Pee is very high in urea and ammonia, and these are a favorite food of algae and some bacteria. This is why your glass will always need cleaning; because the pee hits the glass before anything else, and algae on the glass consume the ammonia and urea immediately (using photosynthesis) and grow more. In the ocean and lakes, phytoplankton consume the ammonia and urea in open water, and seaweed consume it in shallow areas, but in a tank you don't have enough space or water volume for this, and, your other filters or animals often remove or kill the phytoplankton or seaweed anyway. So, the nutrients stay in your tank. Then, the ammonia/ammonium hits your rocks, and the periphyton on the rocks consumes more ammonia and urea. Periphyton is both algae and animals, and is the reason your rocks change color after a few weeks from when they were new. Then the ammonia goes inside the rock, or hits your sand, and bacteria there convert it into nitrite and nitrate. However, the nutrients are still in your tank. Also let's not forget phosphate, which comes from solid organic food particles. When these particles are eaten by microbes and clean up crews, the organic phosphorus in them is converted into phosphate. However, the nutrients are still in your tank. So whenever you have algae or cyano "problems", you simply have not exported enough nutrients out of your tank compared to how much you have been feeding (note: live rock can absorb phosphate for up to a year, making it seem like there was never a problem. Then after a year, there is a problem). So just increase your nutrient exports. You could also reduce feeding, and this has the same effect, but it's certainly not fun when you want to feed your animals

I can see why you like it so much: http://animal-world.com/encyclo/marine/angels/GoldenAngelfish.php

Well I'm a fan of the great number of blue pastel colors you have.

Hi, can we do a giveaway contest too?

I've been posting this link around a lot, and almost nobody has heard about it yet.
