I’ll get more pics tomorrow. It’s kinda brownish color. I had green hair algae about 2 years ago and it always stayed together and I was able to pull out of tank, this sort of melts when I try to pull any out.Pictures are not clear, it look like green hair algae...is it long hair like or is it slime?
Test kitWhat's your twat kits?
Take better picture for the algae please.
Take some of the algae out, out it in a cup of salt water and take a picture you might get better picture.
I have not seen it. I’ll search for it.Yeh the microscope pictures really look like a strain of cyano. Btw cyano is not always red. There are brown cyano.
There is a cyano vs dino va distom test method I have put on a post a while back..it involve testing using a cup and a filter..have u seen that post? If you have, can you do that test so we get more data?
How are you testing your po4 no3 then?Test kit
Kh = Hanna
Ca and KH was Red Sea until I realized it is expired by 2 years I got a Salifert and my calcium was well over 500 and expired Red Sea was giving me 450 result.
Now everything is salifert.
Thinking about ordering the ultra low phosphate Hanna because the light colors are a killer, but it’s pricy...
Salifert right nowHow are you testing your po4 no3 then?
This sounds like a great experiment! I’ll have time this weekend.To identify dinoflagellates you'll need to siphon some algae into a container preferably with a lid or cap. After filling up the container shake the water up vigorously to break up the algae. Then filter the water through a paper towel or filter sock, the water should be rather clear. Leave the water exposed to ambient light in this container for 30-120 minutes. In my experience dinoflagellate algae will be the only type that aggregates back together quickly in the container
Dinoflagellates will disperse in the container completely after being shaken and will pass through the filter almost completely with only detritus remaining in the filter. Once the filtered water has been left sitting in ambient light for about an hour they will organize back together into their typical slimy appearance. Dinos seem to be the most neutrally buoyant of the three.
Cyanobacteria will typically stay matted together even after shaking the capped container vigorously with lots of small bits resembling torn paper. Most of the algae will be caught in the filter with the detritus but the filtered water will still be discolored. The algae will not organize back into colonies after an hour. The water tends to stay brown but sometimes the cyano settles on the bottom of the container. Cyano seems to be close to neutrally buoyant most of the time.
Diatoms will disperse much more than cyano when shaken vigorously into a brownish tint but sometimes tiny bits stay together like the cyano. Much more of the diatoms will pass the filter compared to the cyano. The diatoms will not reorganize after the filter and they tend to be more negatively buoyant than the cyano or dinos so they settle on the bottom of the container faster.
I have a hunch your po4 and or no3 are not really zero.Salifert right now
