mine are similar to tubs in this same section but didn't want to overtake his thread and instead opened mine as the situation is a bit different.
i had requested confirmation that the below was indeed GHA in a separate thread:
https://www.livingreefs.com/green-hair-algae-and-prognosis-t41782.html
but only yote responded that it possibly could be.
this is what it looked like originally:
i followed his advice and removed about 80% of it that i could which left a perfectly white sand underneath.
that lasted 12 hours before small islands the size of quarters of the same algae began growing again and now has come back worse than it was before.
for the last week, i've cut back my feeding to 3/4 a cube a week.
i replaced my GFO six days ago in case it was time, i tuned my biopellet reactor off in case they were clumping and causing an outbreak.
i change 35% of the water every week, this is in a 46g with four fish.
phosphates are reading .02ppm and nitrates/nitrates at 0ppm. pH at 8.4
light is on for 10 hours a day.
there is plenty of flow over the area with 2 mp10s (one at max 100% and the other 80%) covering the space.
two days ago it looked like this - the islands had gotten much larger:
now it looks worse than the original photo at the top.
can anyone confirm that this is GHA?
can someone else offer advice on what to do or what to check?
should i invest in some turbo snails (my crabs have killed and eaten all mine off)?
should i just keep removing what i believe to be GHA?
could a dirty skimmer be a catalyst for something like this? there is some green algae and coralline in my skimmer cone.
thanks for any help you can provide!
