All's you got to do is ask.
PH is steady 8.3. Back when I first go these things, November I think it was, I raised the PH to 8.5 using Kalk for about 3 weeks. No change in dino growth. PH has been known to help but usually in combination with "lights out". There are also many species observed to be unaffected by PH. I also use carbon regularly, I syphon out dinos on an HOURLY basis. And as for water changes I have tried no water changes and daily water changes. They definitely get worse with more water changes. I do use a filter sock, I use 4 in fact. I change them out every other day.
Sewage run off is a theory but is by no means endemic since the first recorded incident was in Canada in the 1700's... The following is from wikipedia
Causes
The occurrence of red tides in some locations appears to be entirely natural (algal blooms are a seasonal occurrence resulting from coastal upwelling, a natural result of the movement of certain ocean currents)[12][13] while in others they appear to be a result of increased nutrient loading from human activities.[14] The growth of marine phytoplankton is generally limited by the availability of nitrates and phosphates, which can be abundant in agricultural run-off as well as coastal upwelling zones. Coastal water pollution produced by humans and systematic increase in sea water temperature have also been implicated as contributing factors in red tides[citation needed]. Other factors such as iron-rich dust influx from large desert areas such as the Saharan desert are thought to play a major role in causing red tides.[15] Some algal blooms on the Pacific coast have also been linked to occurrences of large-scale climatic oscillations such as El Niño events. While red tides in the Gulf of Mexico have been occurring since the time of early explorers such as Cabeza de Vaca,[16] it is unclear what initiates these blooms and how large a role anthropogenic and natural factors play in their development. It is also debated whether the apparent increase in frequency and severity of algal blooms in various parts of the world is in fact a real increase or is due to increased observation effort and advances in species identification methods.[17][18]
I wish it were as simple as sewer run off b/c then the task of finding a reliable limiting factor would probably have already been discovered, along with specific tank parameters that inhibit their growth. Problem is you can find anecdotal evidence of dino blooms from just about every style of SW tanks. However LNS are definitely more inclined to allow them to grow.
