Dinoflagellaten Part II

It’s about a year ago I have reported about a dinoflagellates plague in my aquarium and how I handled this issue.


At that time I was struggling with a strong dinoflagellate infection that took over a year to get rid of it. This was followed by a light cyano infection, that was gone after a short period of two weeks.

I had tested a lot of different approaches, to fight the dinoflagellates successfully. Finally I could eliminate the plague with a silicate filter that I installed in addition to my osmosis system.

Now about 15 months later a slight cyano and dinoflagellate infection appears on my sand. My previous experience has shown that cyanos are often followed / accompanied by dinoflagellates. As this situation can get serious it’s particularly exciting how this population now establishes. The most impressive study for me is the rehabilitation ability of these creatures, that can bee seen after vacuuming them within a water change and how long it takes to rehabilitate.


So why are they back again?

Since I posted the solution of the problem last year by the use of the silicate filter, it is clear for me now, that the ability to absorb silicate of the granulate is now extended/saturated. Over the last 15 month I produced approx 2915 liters with my Osmosis System + silicatefilter. During 64 weeks I produced 45 liters per week(25L waterchange and 20L refill). I used about 1 liter of granulate in the silicatefilter.

Now I’ve replaced the granulate at the weekend and I’m curious if / when sand will be clear of dinos.

What are your experiences with silicatefilter with respect to cyanos or dinos?
How many liters of water you can produce per liter of resin ?

I’m very interested in your thoughts.
