Never ending cyano battle! Help!

[Jonesyg]

I have been battling red cyano ( I believe) for the best part of 6 months, I originally thought it was due to excess nitrates and phosphates. I addressed this with a refugium and a reactor with gfo which has brought down both the phosphates and nitrates however the battle is ongoing. Any suggestions or advice or do I just admit defeat ??

Steps taken

• Increased flow all over
• Removed all the algae from the sand and rock works and have blacked out the tank only for it to return.
• Removed white spectrum light
• Removed red spectrum light
• GFO reactor
• Refugium with chaeto
• Dosed nopox (now not dosing)

Parameters

• 525litre
• Salinity 1.025
• PH 7.8-8.1
• Alkalinity 8dkh
• Magnesium 1360
• Calcium 420
• Phosphates 0
• Nitrates 1.5ppm
• Feed one cube frozen food per day

i'd highly recommend Vibrant. I've used on my older existing tank vs Cyano and Dino's and again with a newer 200G tank. If the outbreak get's pretty bad, i'll use it 2x per week (1x per week is their reco for a "dirty" tank. Works wonders and no visible problems with corals or fish.

Proper biodiversity will keep the algae in check.

Truth be told that cyano isn't very bad.

This is 2 days after a black out and removing every trace of it from the tank.

I have tried "red slime remover" which didn't work, would rather find the cause than use chemicals. But if its my last choice then maybe

Here is something to consider. Indonesian Trochus snails. My nutrients became imbalanced which lead to a nasty cyano outbreak and because my tank is SPS dominant I didn't want to try any chemicals that could potentially harm my colonies. I read trochus snails eat it....I took the risk an ordered 25 for my 300 Gallon from Live Aquaria. I received them yesterday and wow...where ever cyano is they are. This morning I took a look and my tank has improved big time. It is important they are from Indonesia, my understanding are the ones from Nicaragua aren't nearly as effective. I hope this helps.
