Hello Everyone. I have been following this website for months. This is my first post. I have been in fish keeping hobby since over 20 years. But i started my first nano saltwater tank (24g) in July. Cycled with dead shrimp method and everything went according to plan. Cycled completed. Added a clownfish and a blue green chromis and a mandarin goby along with a cleaner shrimp and 5 snails as cuc. Tank parameters have been great. Added a few hardy corals. Like xenia, gsp, candycane, zoas and a torch. They been doing great too. Since 2 weeks i have been seeing dinoflagellates in my tank. They seem to be gooey slimy with bubbles. I dose 2 part also. My lfs guy told me to do a wc which made things worse. They are mostly in the highest flow area but now spreading on sand too. I notice the bubbles return when light is turned on. Bubbles go away when lights are off but brown stuff still there. Been researching alot i came to the conclusion that the wc did it worse as there might be low nutrients in tank. I got water tested. Nitrates were 10 and phosphates 0.8..i use rodi water only with 0 tds. Redsea reef pro salt.
Parameters:
Nitrates: 10
Ammonia: less than 0.05
Nitrites : 0
Calcium: 480
Magnesium 1200
Phosphates: 0.8
Alkalinity :8.3
Salinity 1.025
Temp 24c
Im running a skimmer and have a small refugium with chaeto algae. Seeing dinos approx since 2 weeks. All fish and corals fine and snails too. No deaths so far. Increased flow too by buying jebao sw4 wave maker.. tank is becoming browner each day. I tried to cover everything if i missed anything lemme know. What am i doing wrong or what should i do to eliminate them. Kindly help.
Also tried to manually siphon them worked but they came back. ( can't get it tested under a scope in my area)
Attaching pics and video.
