how do you know you have dinos??


it is very hard to get rid of dinos if you have it, most times people mistake it for cyano. to my knowlege dinos can only be id'd under micro scope;)

cyano also cause similiar bubbles to dinos:)

Well, if it is cyano I'll be much happier. :)

I wonder if the red slime remover that I picked up today would nuke brown cyano, too?

Interesting. My new fox face eats cyano. He's picking it off the Duncan.

Thanks :)

I was hoping it would be more accurate than that, but at least it will tell me if my media needs changed or not.

i dont think they can make it that accurate because there has to be a difference between your reactor and your display.

if phosphates are added to your tank, which is inevitable, the reactor turns them into zero. there has to be the change over period.



ive heard of fox faces mucnhing cyano before so thats a good thing:)

yup it should for sure:)


just follow instructions to a tee:)

You have to find what works and just stick to it, I have a 90gal heavy fed and 500ml BRS HC GFO changed every 3 weeks works for me, I regenerate my GFO to save money.

Hmm. I don't think ROWAphos can be regenerated. I'm going to have to investigate. It was quite costly, and that certainly affects my willingness to change it often.

It has to be high capacity GFO to regenerate it, the reg stuff disintegrates too easily, I don't know if rowaphos can be regenerated.

I know you want phosphate to be as low as possible but what is the accepted maximum for an Lps reef

0.03 is the number i see commonly quoted as a targeted level for PO4. Your test accuracy, as earlier mentioned, is about this, so anything from 0.00 to 0.08 would be within a range I would be happy with. If it was on the higher range in there and I were having algae issues I might try running more GFO, but I would say with your current levels changing it now would have little to no noticeable affect. Pulling PO4 lower than about 0.03ppn will likely result in bleaching of sps and slowed growth as PO4 acts as a seed crystal in the coral's calcification process. If you are running a system that is having algae issues with PO4 around the 0.03ppm, look at your sources and sinks for PO4... you can have low levels while still cycling a lot through the system, it just gets taken up quickly by your sinks. In terms of cyano or Dino's, I often see issues during summer with them in many tanks. I suspect it has to do with increased silica levels in the tap water as my RODI system seems to get plugged with brown scum much faster during summer months and tank blooms seem to be much more common during summer (from what I've seen). I have had less issues since running RODI, but that's just me :)
