Makes u wonder what went wrong......

The 1st picture is a picture of my fish only tank that prob got no3 of 50+ n high po4. the only equipment running is a skimmer and some cheap led lights. But coraline algae is growing everywhere.
2nd pic is my sps tank. No3 3 po4 0.05 dkh 8 cal 450 mg 1400. running radios g5s, skimmer, ats, clarisea filter, uv, but its covered with gha and dino.
Makes u wonder what really happened lol. I did dose my fish only with chloroquine phosphate.

Maybe fish ate the algae before it could get going in their tank

I feel like it’s because your lights for the sps tank are more powerful. If you were to use that light on your fowlr, I’m sure it would grow gha.

I’m a huge fan of algae scrubbers, they’re very effective and very cheap if you diy

Do you use a turkey baster on your rocks every now and then especially during a water change? You’d be surprised at how much stuff gets trapped in there leading to nuisance algae growth!

I do run a algae turf scrubber. It was so efficient, it stripped off all the nutrients to 0. That's why I'm experiencing dino atm.

Do it on a daily basis haha

On your "algae" - do you see any visible gas bubbles on them when the light i fully running?

I think that your example is a good example that the easy answer - high nutrient -> algae not always is the truth. As other have highlight - light intensity play a role - but IMO not a major role in this case.

Organic matter on the rock will not play any role for most algae - however it can play a role for cyanobacteria and some times for dinoflagellates.

First thing to do - try to establish if it is common algae or Cyanobacteria and/or dinoflagellates.

Look at this thread

I'm at a loss... SOS

Ok so I I'll try to make this short... My girlfriend has a 45G tank with a 20G sump thats about 1.5 years old. Her ex-husband set it up for her and then promptly left without passing on any information on the tank or how to care for it. I have literally never had a fish tank so this is all new...

Mentioned in my ori post that I have both gha + dino

 

[Lasse]

GHA is not an biological definition - it just says Green Hairy Algae - IMO there is many hairy cyanobacteria thats is misnamed as Algae with the common name GHA. Therefore I ask if you could see any gas bubbles in what you call GHA. If you can - I doubt it is an algae. How have you identified the things you call dino - by microscope?

Yeah they do have air bubbles.

You have a lot of advises in order to "starve" them out - you have also done a try with that - it did not works out well what it looks like.

If I was in the same situation - I would have mechanical clean the stones. going down with light, maybe only use the blue wavelengths for a while. Try to establish around 2-3 ppm NO3 and at least 0.05 as PO4. if they come back - clean again and clean again
