Dino disaster

jacobcoral · Jan 1, 2026

I’ve been dealing with alage for about a month now and have approached it many different ways. First it was terrible Dino’s and GHA, so I did a 3 day blackout and the it got rid of Dino’s but not GHA so I dosed Flux Rx let it do its thing did a water change 2 weeks later and then GHA was gone, but now I have Dino’s and maybe cyano. I have a pink Goni that’s been ticked ever since I dosed flux rx and won’t extend at all. I’m not sure what to do at this point and it’s very frustrating. I’ve been patient and tried many things and will give it one more shot. The kind of Dino’s I have don’t go away with uv that’s all I know. So I’ve been dosing bacteria, phytoplankton, and silicate for a diatom bloom. Anyone have any other suggestions?

How old is your tank? Maybe your tank is still going through stabilisation cycles. It looks a bit like it is an establishing tank. In that case the solution is to stop dosing anything and have patience. Keep the light low and ride through the “uglies”.

You can try all things to get rid of a certain type of algae, but if your tank is not mature (microbiome, copepods, bacteria,…) it is just restarting another battle and the next strongest type of algae breaks out. Make sure you have enough and the correct type of clean up crew. Add A LOT OF copepods, feed them some phyto and have them clean your tank. Get some snails. (Trochus, cerith, nerith, nassarius). If your tank is funning a long time have a look into a tuxedo urchin. And plan your fish stock with some herbivores that will naturally reduce algae.

What are your nitrates and phosphates?

It took me 5 months to beat dino's, then it took another 6 months for the tank to recover and for corals to start growing again. Quick fixes don't work, it is a long battle, it takes months to beat out any kind of algae really.

A full tank pic and more details on your set up will help. What are the parameters, how is the flow in the tank? How is the filtration, water changes, etc....
