  1. Chaeto Reactors compared to Algae Scrubbers

    Will consider, thanks.
  2. 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.
  3. DIY Internal Algae Turf Scrubber for Biocube 29

    Both of those are way too big ... they are 12" across. A small 6 watt LED grow light would work.
  4. Automatic Brine Shrimp Hatchery

    I thought at first you meant a ready-to-buy unit, which I've been looking for. For yours, it seems a sticking point is flow into and out of the bottle, when there should be no flow.
  5. Mushrooms bad with sps?

    Just start your sps out small, and see if they grow. If they do well, they will do even better when bigger.
  6. The many methods of training Dragonets

    Not really. But got a chance to reach the first post and it was great training info.
  7. Using Seaweed to get rid of nuisance algae in your aquarium or pond, part 2 So how does photosynthesis "pull" the carbon it needs out of the air or water? Doesn't CO2 or other nutrients just "soak" into things by themselves? For example, doesn't CO2 just soak into trees? Meaning, if you have more trees, won't more CO2 just soak into them? No, not really. CO2 and other things do "soak" into water, but the reason that the water does not "fill up" with CO2 is because organisms in the water "pull" and "eat" the CO2. What organisms might these be? Algae, of course. Or more specifically Photo-Auto-Trophs (photoautotrophs), which means they get their food (carbon) all by themselves (auto), without needing to eat other animals, and they do this using sunlight (photo). In the open ocean and open lakes, all this is done by free-floating algae (phyto plankton), but as you the get to shallower areas of the reefs and lake shores (and in streams and shallow rivers), it is done by benthic (attached) algae on the bottom surfaces. We will be calling all attached algae "seaweed", even if it's in freshwater lakes, because saying "lakeweed" is a bit odd. The faster that carbon is taken out of the water by the seaweed on the bottom surfaces, the faster CO2 can continue to absorb into the water at the water's surface. This is an important idea to understand; it forms a CO2 "gradient". This idea is easier to explain by thinking about an oven: Standing far away from an oven, you might barely feel the heat, but as you move closer to the oven, your temperature rises. So even though the oven is making the same heat, the amount of heat you feel depends on how close you are to it. With seaweed on the bottom of the reef or lake, the amount of CO2/carbon the seaweed "feels" depends on (among other things) how close the seaweed is to the surface of the water where the air is, because this is where CO2 is being absorbed into the water from the air. This is one of the reasons (besides light) why all the phytoplankton lives near the surface of the water. Seaweed however is far from the water surface, and water that is next to the seaweed (say, 1 cm away) has had so much carbon removed that there might be little carbon remaining. So by making the air more near to the seaweed, it feels and has access to more CO2/carbon. This "near-ness" of air to the seaweed is what makes things work for our filtering needs.
  8. Bowing tank question

    Could always lower the water level to make a Volcano Tank, and if it leaked it would not be much. Could keep the corals too.
  9. Eshopps Curve Refugium light

    If you can use red or plant-grow LED's, you will get faster growth (filtering).
  10. Red sea peninsula tank coming!

    Love peninsulas
  11. Flow question [?]

    That seems super strong. Might make some softies mad.
  12. Bowing tank question

    If you could past an arrow on to the pic where you see the bowing, and take a pic longways, it would help.
  13. dried rock with coralline algae

    One trick to seeding is to blend someone else's coralline in SW in a blender, then mix it into your tank.
