Current Tank Info: 400g mixed reef with refugium/sump, Orphek V4 LEDs, Deltec protein skimmer, Ecotech MP40s, phosphate reactor (now off-line), charcoal reactor, Apex controller, 3 part dosing.
My saga started 6 weeks ago. Before heading on vacation at the end of July (six weeks ago) I noticed what I though to be a little Cyanobacteria forming in my aquarium. This was a usual occurrence for me in the summer which always seemed to go away in the fall. My tank is in the main room of a loft and thus receives quite a bit of natural light. This seemed to happen every summer and I always blamed this excess light during these long Canadian summer days as causing my annual cyano blooms. I’ve always ran a fairly low nutrient tank as I believed what most sources in the hobby said. Consequently whenever I had any trouble I always did some large water changes and beefed up my carbon and GFO. Worked for the most part over the years.
This year, before heading away on vacation I decided to “really get on top of things”. I did a large 30% water change, suctioned the detritus out of my sump, suctioned my sand bed, rinsed my Chaeto, and replenished my GFO and Charcoal. Then I hopped on a plane for a 2 week vacation. Literally 2 days later the person coming to feed my tank sent me pics of this “brown stuff that was growing everywhere”. I thought it was just more cyano. I reassured them and told them to reduce the feedings. Of course this only made things worse. By the time I got home the tank was absolutely covered in brown slime. As the guys from my LFS who help maintain my aquarium from time to time when I'm away had seen this in previous years and confidently identified this as a type of Cyano I just assumed it was. When I got home after 2 weeks I went to town battling "Cyano". More water changes, aggressive suctioning and driving down any traces of nitrate and phosphate with a 24h Chaeto fuge cycle.... and yup, you guessed it things only worsened. I was getting nowhere. I was getting desperate. Over the years I strongly believed in the natural approach to dealing with problems and had never added any antibiotics or the like to my system, but I was at my whits end and decided to try Chemiclean for my "cyano". And guess what? It didn't work! During my experience with Chemiclean I posted some pictures of my tank and posted some youtube vids. From this someone said "I think its dinos that you are fighting, not Cyano". They were right . And looking back at pictures of my "summer blooms" I think I've been battling dinos for years and years. Just never this bad.
I bought a microscope and confirmed diagnosis (see below) and subsequently started reading everything I could on Dinos. @mcarroll I can't thank you enough for your thread. It's given me hope!
Thus my approach has been:
-Stop water changes.
-Take GFO off line.
-Change Charcoal frequently (q 5-7 days)
-Add UV sterilization (I first picked up a 12x turbo twist as that was all my LFS had, but have since added a 90 watt high output promax UV sterilized from lifeguard aquatics for a total of 126 watts. The 90 is now hard plumbed into my main return running at 600gph. The TT is running off a second parallel pump at 300gph for a total of just over 2x /h turnover).
-Dose Seachem phosphate and nitrate (this has been a bit of a rollercoaster so far. I started at 30ml / day of each and measured with my Salifert kits each day. After 2 days Nitrate showed a trace but phosphate was still undetectable so I upped it, first to 40, then to 50ml. Finally after 5 days I had my first positive reading of phosphate! I added a total of 120mls before I got my first + reading. I'm now at 5-10 nitrates and approx .5 for phosphates.)
-Daily night time blowing all the dinos into the water column with a powerhead.
Now it's really only been 2 days since I've had my nitrates and phosphates above my goal level and plumbed my UV sterilizers into the system so of coarse I haven't seen any improvment yet. WISH ME LUCK!
And if anyone has any criticism or advice, this is what I'm posting for! Fire away!
Video I posted pre-Chemiclean when I thought I was battling Cyano:
Attached are some pics of the aquarium when this all started as well as some pics of my dinoflagellates looking through my microscope.
Will update regularly.
