Going to start treating my tank today. Any advice? Have enough on hand to treat for 4 days.

Will def be testing. Did a search here & read everything on cyano & that was one of the things Rivercats mentioned.

Good luck! Would be interested in results as have only ever used h2o2 on a small patch. I have a note that nitrates under 10ppm can encourage it and wondered if you had found this to be true?
 
I do think that s possible. I read that a few weeks ago & have been adding nitrates . But maybe they ve been low for awhile & that s why the cyano took over.

At the time my nitrates had dropped down and were around 10'ish and trending below so I thought this could be plausible.

Since then nitrates have always been up and never seen it but could well be other stuff going on.
 
Rodeo - Did you start treatment already? If not, then do a big water change prior to this. While siphoning out the water, remove as much cyano as possible. I cannot remember when a WC is recommended but I think I did not change mine for 10 days. Treatment for 5 days. Most of the cyano was gone by then. Even after day 6 the EM will still be active and the cyano will be in the process of dying.
Good luck!

Hi Fresh. Yes, started treatment yesterday, did a very thorough cleaning, threw away the DW & did a rock arrangement instead. The DW seemed to be Cyano Central.
Tested tonight , ammonia 0, nitrate 10, phos 2. Only had the funds for 4 days of treatment ?, but will def wait & do a WC in 10 days. Also set lights for 4 hrs.

Was going to wait 10 days for a WC but today's tests show ammonia .25, nitrate 40 & phos 5 so will do a 50% WC this am. Just need a little more coffee. Wondering if the high nitrates are due to cutting back a lot of the plants before I started tx.

Yeah, fish health comes first. Are you seeing a reduction in BGA? It may continue for the next few days even after the WC.

Glad the treatment worked!! did it fuss with the bio filter? You can use a 3rd party image hosting site, fresh can help with that. I'm lazy.. i just paid the $14 for premium membership;)

I have the paid membership, but mostly for the unlimited PMs. I have posted pics in my albums, but accessing the albums with a mobile app is a challenge.
I use Imgur as a photo hosting site. Sign up, create an account, upload pics, grab the URL/links to the pics, paste them in you posts. Was using an app called ImgurApp to do the above tasks but had trouble with it so now I am using an app called Pocketgur.
There are other 3rd party sites you can use such as Photobucket and possibly Flickr.

Just downloaded Photobucket so will see if I can figure that out. Thanks for the help & encouragement :). I didn t have the funds for the membership, hubby not working & 3 50g tanks to maintain equals no extra cash.

Congrats on beating the BGA and the photobucket posting. Tank looks nice.
