Cyano problem - 0 nitrate & 0 phosphate??

[Randy Holmes-Farley]

Do you know of anything else I can do to address my nutrient problem?

I too would try good sized doses of GFO.

If low nutrients can solve a cyano issue and cyano is a bacteria, why do other bacteria grow in low nutrient tanks?

They all do, but presumably not in plague proportions.

This is the product that my LFS carries:

Kent Marine Phosphate Sponge Filter Media

Is it acceptable for this purpose?

Is it considered a GFO?

Randy, can you help me here?

 

[Randy Holmes-Farley]

No, that is not GFO, it is aluminum oxide. It may work OK, but I'd use an iron based one such as Phosban, Rowaphos, Salifert Phosphate Killer, etc. They are all red to black in color.

i have one spot of cyano. it is in a high flow area (basically the whole tank is high flow) and i only 5fish and feed lightly. even if i fed every other day it still stays in that one spot. i use decent sized doses of phosban and Rowaphos (mixed) in a 2 little fishies reactor and dose AZNO3. AZNO3 was used to see if it would help win the battle on bryopsis.

so i still have high nutrients? many people think i have too low of nutrients..so low that my corals are light colored

thanks

Randy, correct me if I am wrong, but would dosing AZNO3 not provide a carbon source for the cyano and possibly make a cyano problem worse??

BTW lunch, there are many other factors that can cause light colors other than nutrients. I wouldnt say that just because you have light colors that your tank has rock bottom nutrients, though I agree, they are likely not very high....

 

[Randy Holmes-Farley]

I do not know whether it helps cyano, or robs nutrients from it. I've not heard of it causing cyano to get worse.

I placed an order for some gfo, chemi pure and 10 additional cerith snails to hopefully help with the nutrient export process. Hopefully this coupled with macroalgae & skimming will help solve my excess nutrient problem.

Randy, I quickly read your article on Iodine and macroalgae and was wondering if iodine has anything to do with cyano. I currently dose Lugols weekly because of the benefits I have heard it has on SPS tissue. Perhaps I should stop since you don't generally recommend Iodine supplementation at all.

 

[Randy Holmes-Farley]

No, I don't think iodine supplements will impact cyano one way or the other. Same for SPS.

So if you get your nutrients low with respect to hobbiest levels, how does that get rid of the cyano? It sounds like the cyano multiplies as fast as other bacteria which survives in our tanks?

I ask because some people with excellent husbandry still can't get rid of the cyano.

low nutritient --> rinse frozen food before feed. stop using filter feeding food for a while. Efficient skimmer --> min 3 cups/week

Well, it usually works for both cyano and green algae, so apparently, cyanobacteria and green microalgae are not the most efficient organisms in the tank in terms of nutrient uptake.
