Macro Algae Growth

[GMeWu]

What happens when there is too much growth on my macroalgae? If i cut some or pull some out, wont it release toxins into my reef tank?

Also where can I buy Chaetomorpha online? From what im reading that seems to be a very good macro for a refugium.

I was looking at the refugium flora kit by inland aquatics http://inlandaquatics.com/prod/prod_refu.html. What do you guys think of it? Thanks~!

Also I am using my old 10000k/actinic lighting for my refugium. Would I need to switch to 6500k?

I have 5" mud bed for my refugium 20 length x 12 width. What types/mix of macro's should I plant and where can i buy them? Thanks!

When you prune your algae, you should try to pull entire strands from your substrate without breaking any. If you need to break it, pinch it in two to help seal off the broken ends. Personally, I have unceremoniously ripped out tons of grape caulerpa without noticeable changes in my tank, but after reading the risks of doing that, I try to be more careful!

eBay is a good place to get chaeto. Ofter, you can find it through fellow reefers who are looking to thin their stock.

That refugium kit looks like a very nice one.

Your 10,000K light will work fine for now. You'll have faster growth with something closer to 6,700K (true daylight), but if I were you I would just wait until the bulb burns out. Even as the bulb gets old, the spectrum will shift over to something algae prefers. You will still have great growth under your bulb.

As far as what types of macros, it looks like you'll get an assortment in your refugium kit. They will all work well. I use an array a caulerpa, but I do this knowing the tendency of caulerpa to go sexual and the risks therein. I am getting some chaeto today also. It is good because it doesn't go sexual, but it doesn't have a root system. I think a variety is good because each species will uptake different amounts of specific nutrients.

Very good job asking questions! It seems as though you have done good research and are looking for real life experience to back it up! Kudos!
