Unfortunately, my tank is not looking very good at the moment... Have been battling what I initially thought was cyano... But after 4 weeks of treatment with KZ Cyanoclean and no improvement, I really started to doubt the initial diagnosis.
So as I learned from the other thread, these are dino's (most likely Prorocentrum). Since I started with dead rock, I most likely went to fast and now have to pay the price. Patience does go a long way...
Last Friday I started what seems to be proper treatment for this. Nutrients have been near zero/undetectable for a week or two, which seems to counteract the treatment, so increased feeding a bit. Nutrients are now at a slightly elevated level (NO3 is 19ppm, PO4 at 0.08 ppm)
Putting a filter sock in the sump each night and with a turkey blaster I am cleaning the rocks and sand. I repeat this in the morning (and let the filter sock run for about 20 mins), than I take the filter sock out.
Besides this, also some positives, I received my RFG, so will be installing as soon as I have some time to upgrade my loc line (measured wrong, so will upgrade to 1/2"to fit the RFG).
