Curious. I have a bad/recurring case of Cyano in one tank in particular (which may have also cross-contaminated to our two other tanks? Unsure there...looking for advice to end this completely in all. All that being said I also have a question that relates directly to this AQ Coop Blog: https://www.aquariumcoop.com/blogs/aquarium/blue-green-alga
Simply the blog states: "To begin treatment, scrub off as much of the blue-green algae as possible and remove it with a siphon. After vacuuming the substrate and refilling the tank, add one full dose of Maracyn (which is 1 packet per 10 gallons of water), and let the aquarium sit for one week before doing another water change. The earlier you treat the outbreak, the easier it is to eradicate. If the blue-green algae is very thick and widespread, you may need to repeat the treatment several times to completely remove the colony."
So on the Maracyn packet, it states to dose for 5 days? Wondering did I read something wrong in the blog or on the Maracyn pack? Or is the direction different in the blog as it writing towards the purpose of killing the Cyano vs. curing fish?
And to provide some extra background info: I did do this about 1.5 years ago. When I did so, we went on vacation and my brother & nephew maintained the last day or so of the tank meds. Upon return we had lost 1 frog (2 survived). Unsure if that was due to the meds or otherwise. Also upon return the tank appeared to have No signs of Cyno? But maybe something was re-introduced, or other-wise.
A few more details about the tank. I chose the Maracyn route as I understood it is considered generally safe for the African Dwarf Frogs and and the Cyano was all over more or less. I had initially thought it was just algae and that I needed another snail. 😞
Also the sand has plants: some low growing Valisneria (it never grows high, maybe due to the cyano?), a few/two? buce plants, and a sand substrate (horrible with the cyano!). It's a 20L with an Aquaclear 30 filter. There is also an Volcano with some air pumping through it.
Currently this tank houses 6 cherry barbs, 2 ADF's, a pagoda snail, 2 horned nerites, and 1 kupa nerite.
Much appreciate the assistance.
