How do macroalgae reproduce?
Compared to higher (vascular) plants, macroalgae have quite complex life cycles, and a wide variety of modes of reproduction; most algae reproduce by releasing sexually or asexually produced gametes and/or spores (propagules) and by vegetative spread and/or fragmentation (breaking off of plant pieces to produce new …
What kind of algae is in a refugium?
When it comes to algae, I recommend Chaeto or Chaetomorpha. This is the standard algae for refugiums, which is for a reason; it is easy to care for, grows fast, and is very effective. You can choose a different kind, but for a beginner, Chaeto is the way to go.
How do macroalgae grow?
Macroalgae grow both intertidally and subtidally. Because they derive their nutrients by diffusion through their tissue, the water movement across fronds has to be continually refreshed and by being anchored to the seabed, they increase their chances of this.
Do Refugiums lower phosphates?
Refugiums and Algae Scrubbers An algae reactor/scrubber or refugium with macro-algae are both excellent options for phosphate control as well. A refugium with macroalgae will remove phosphate, nitrate and other nutrients via the fast-growing macroalgae.
Does macroalgae lower ammonia?
This is the biological process that keeps our tanks inhabitable for marine life. macroalgae can reduce nitrates which is the end product of ammonia.
Should you clean out your refugium?
The point of having a refugium is to remove grown algae. If you don’t remove algae you aren’t removing the contaminants. I do agree 2 months is fairly new and you could wait a little longer but you get my point.
Does Chaeto eat ammonia?
No it does not absorb ammonia. Bacteria breaks down ammonia into nitrite and other bacteria break nitrite down into nitrate. Nitrate is then a source of nutrients for algae and other things.
Will a refugium remove phosphate?
What is the mode of reproduction in algae?
Many small algae reproduce asexually by ordinary cell division or by fragmentation, whereas larger algae reproduce by spores. Some red algae produce monospores (walled, nonflagellate, spherical cells) that are carried by water currents and upon germination produce a new organism.
How long does it take for algae to reproduce?
Microalgae grow fast, and some can double in size in 24 hours. The other type of algae, macroalgae, are more commonly known as seaweed. They are fast-growing marine and freshwater plants that can grow to considerable size.
