i thought this was gha and was treating it with h202 and water changing but now im wondering if it may be dinos. and what are the steps to get rid of it thanks!
update tank is looking a little better corals still not opening up alot and i have been doing 4-5 hours of light a day they seem to get really bad when the light is on
Its Dinoflagellates. The problem arises when conditions in the aquarium break the biological balance and some dinoflagellate species spread uncontrollably, smothering the rest of the aquarium inhabitants. If the dinoflagellate species in question has the ability to produce toxins (usual in ostreopsis, gambierdiscus and prorocentrum to name a few)
The problem often arises when we try to bring cleanliness it to the limit, in order to improve its appearance and color of corals.
They tend to occur suddenly when the aquarium water reaches an extraordinary cleanliness, in which most microorganisms perishes for lack of food. With no other organisms that can stop them, this type of dinoflagellate can multiply so fast that when we realize it's late and we will find an aquarium full of brown and ochre slime suffocating fish and invertebrates. These dinoflagellates possess chloroplasts enabling them to synthesize their own food even under a minimal amount of light. Some species can form cysts called pellicles which allow them to remain in the aquarium for months although we have completely sterilized or kept in complete darkness. Once the light or the right conditions come back, they will reappear and thus problems.
Most of these dinoflagellates have a very curious behavior, typical of pathogens and parasites. With the presence of light they secrete mucus which adhere to any surface, including algae, coral and fish. They spend hours synthesising food and extending vertically in search of the light source (if we turn off the pumps in the aquarium we can see brown filaments grow towards the surface). When the light source disappears and can no longer synthesize food, it begins to diminish to none.
Prepare by starting with a water change and blow this stuff loose with a turkey baster and siphon up loose particles.
Turn lights off (at least white and run blue at 10-15%) for 5 days and at night dose 1ml of hydrogen peroxide per 10 gallons for all 5 nights. If you dont have light dependent coral- turn all lights off.
During the day dose 1ml of liquid bacteria (such as bacter 7) per 10 gallons.
Clean filters daily and DO NOT FEED CORAL FOODS OR ADD NOPOX as it is food for dinos.
Day 5,, you can start with blue lights - ramping up and work your white lights up slowly
i have been dosing 1m of hydrogen peroxide the last week and keeping up with water changes. i have barely had whites on and have not been feeding and have been scrubbing it every day. i appreciate all the help!
