Updated parameters.
NO3 = 0.5 ppm PO4 = 0.06 ppm KH = 8.2 dKH It seems that I should reduce the feeding a little bit and/or increase the vinegar a little bit back to 27 ml/day. Or wait a couple more days to see how the system behaves. |

Well, the results are ambiguous to me. I'd probably leave the system unchanged for a bit, but I don't know what will happen.

It seems that the new dosing pump was underdosing vinegar (perhaps 20ml instead of the desired 25ml). I made some adjustments, which applied yesterday and today.
Updated parameters: NO3 = 0.25 ppm PO4 = 0 ppm KH = 8.4 dKH * Perhaps time of day impacts the measures? The previous one was taken around 12:00 and this one was taken at 19:00. I also fed less in the last couple of days... I keep dosing 2 drops of Cyano Clean, as per instructions. No noticeable effect yet. The cyano is still there on the sandbed and some on the glass. Green algae is very little, mostly on the back glass. To the point that I'm a little worried for an urchin that I have. The corals look happy. Last edited by rsucre; 02/06/2018 at 06:46 PM.

The dKH might vary a bit throughout the day due to the timing of the doses and a varying rate of growth, but the difference should be small. Phosphate might make a bit of a spike when food is added, since most foods are going to release some phosphate immediately.

Further to this and as always with nothing more than anecdotal evidence... 1. I found non substantial academic research showing vinegar is the worst carbon source vis a vis other carbon sources. 2. I continued to blow all of the cyano off all rocks and vacuum from sand, continued no carbon dosing, and did a series of 20% water changes whilst all cyano detritus was suspended in wc. A total of 50% water change was conducted. I continued to dose cyano clean and micro bacter daily. 3. All residual cyano has now gone for a period of a week which is longer than prior periods, there has been temporary decreases in NO3 or PO despite the water changes, increasing back to original level, this is surprising however may be a die off in bacteria due to suspending carbon dosing. The rocks and sand look noticeably cleaner. 4. I have resumed carbon dosing at 25% of original 0.8ml/gal dose amount. |

Update: After a few days of monitoring closely making sure that the new dosing pump is dosing 25ml vinegar daily I got the following results:
NO3 = 0 ppm - Red Sea Pro PO4 = 0 ppm - Hanna Phosphorus ULR KH = 8.6 dKH Cyanobacteria still there, as usual. I have dosed the 2 drops of Zeovit CyanoClean daily. No noticeable effects yet. Last edited by rsucre; 02/09/2018 at 09:09 PM. Reason: typo |

Hi Dan, I'm happy for the undetectable PO4 and NO3, but unhappy with the lack of results from the Zeovit CyanoClean. Will keep trying.
I will now increase a little bit on the feeding of Reef Roids and Reef Energy. Little by little, to see if I can get to PO4 = 0.02 ppm and NO3 almost undetectable, maybe 0.25 ppm. |

That's good progress. Finding a bacterial strain that can always outcompete cyanobacteria in a tank is going to be difficult. Please keep us updated on your results!

Cyano is bacteria so you’re likely feeding it by overdosing carbon. Also, do you have chloramine in your tap water? I struggled against cyano for the longest time and tried everything then found out my local water source uses cloramine. Once I added an additional stage to my RODI filter to filter that out, the cyano went away. I always know I need new filters when I start seeing cyano/algae/excessive bacterial film.

If the RO/DI reads zero, and it's sufficiently precise and accurate, the water should be close enough. There are exceptions: silica can pass through RO/DI to varying degrees and I'm sure there are others, but I wouldn't suspect the RO/DI much as of yet. Chloramine can be an issue in some cases, but most setups actually can handle it well enough:
http://reefkeeping.com/issues/2003-1...ture/index.htm You could check the ammonia level in some of the RO/DI if you are very worried. In addition, getting a second opinion on the TDS meter might be useful, if that's not too hard.

My current setup has a sediment, carbon, RO, DI filters in that order. Maybe the buckeye replaces the regular carbon filter? |

It should go after any filter that has a larger pore size, as a first guess. What is the rating for the current carbon block?

Assuming the sediment filter pore sizes are correct, install your carbon blocks with the HIGHEST CAPACITY block first in order of water flow. Russ |

1. 1 micron sediment filter 2. 0.5 micron carbon block filter 3. Filmtec TW30-1812-50 TFC Membrane 4. Spectrapure Maxcap 1-stage resin I get 5ppm TDS after the RO membrane and 2ppm at the end. Questions: 1. Should I just replace the existing 0.5 micron carbon block filter with the buckeye carbon filter? 2. If not, then where should I put the new buckeye filter? |

Update.
NO3 = 0 (Red Sea) PO4 = 0 (Hanna) KH = 8.1 dKH Cyano still there. Little algae on back glass. Still dosing 2 drops of CyanoClean per day as per instructions. Not doing anything noticeable yet. |

Are the animals doing well? How thick is the cyanobacteria?

The animals are doing well. Fish, corals, hermits, all happy. The cyano is just a brown mat over the sand bed and some film on the glass. The brown mat seems to diminish greatly at night, then comes back at daytime. Sent from my iPhone using Tapatalk |

That sounds more like dinoflagellates than cyanobacteria, or at least a mix. Dinoflagellates often show that behavior.

I don’t know for sure, but we are assuming that it has chloramines. I’m having a cyano issue even with very low TDS, zero PO4 and zero NO3. Someone suggested that chloramines could be the culprit. Sent from my iPhone using Tapatalk |
