Trailermann Posted October 5, 2019 Share Posted October 5, 2019 This stringy stuff is most prevalent right below the Hydra 52. It brushes and blows off easily, then the tank is relatively clear for a couple of days. It does not match the on line images I searched for. (Fully cycled 20 gallon coral quarantine tank two months old.) What ever it is, should I be worried and do anything other than brushing it off and letting time take its course?

pdxmonkeyboy Posted October 5, 2019 Share Posted October 5, 2019 Looks like cyano to me. I wouldn't sweat it too much..Sent from my SM-G960U using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Optimusprime3605 Posted October 5, 2019 Share Posted October 5, 2019 I'm no expert, but it looks like dinos to me. PITA for sure, if it is.When I had dinos, I've always noticed my nitrates to be extremely low. Then, I would add nitrates to the tank so algae would out-compete the dinos. I'd rather have algae than dinos. I've heard of people restarting their tanks bcuz of them. Again, only if they are in fact, dinos.Carry on...

Trailermann Posted October 5, 2019 Author Share Posted October 5, 2019 Why is it so difficult to ID nuisance algae? No disrespect for you guys, but even on R2R when aquarists post photos, the answers are rarely clear. When I Google images of dino, cyano, and brown hair algae, none of the results look like my stringy filiments. Quote Link to comment Share on other sites More sharing options...
Bicyclebill Posted October 5, 2019 Share Posted October 5, 2019 I say cyano. Mad Mike taught me a trick years ago to turn off lights for three days while blowing it around. He used to do it up to once a month as needed with no ill effect on his sps dominant tank. Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

Because every tank, flow, nutrients, lighting, camera used are different for everyone so the same algae can look ten different ways in ten different tanks. Looks like cyno, do a blackout for 2-3 days and should clear up. Quote Link to comment Share on other sites More sharing options...
pdxmonkeyboy Posted October 6, 2019 Share Posted October 6, 2019 I called cyano because of the stringiness you claimed and the bubbles, the bubbles are often a tell tail sign. FWIW, in my experience cyano shows up when there is an imbalance in the ratio of phosphates and nitrates. This would also make sense in a newer tank as things... (bacteria) numbers tend to swing widely for a bit. Sent from my SM-G960U using Tapatalk Quote Link to comment Share on other sites More sharing options...
xmas_one Posted October 6, 2019 Share Posted October 6, 2019 (edited) Test your nitrate, if it’s zero then that’s most likely cyano. Especially with the oxygen bubbles in it. Fun fact, cyano is actually not an algae, but a photosynthetic bacteria. These guys are also thought to be responsible for the early oxygenation of our atmosphere.
