Is Api algaefix safe on fish

[Mike7744]

Anyone using API algaefix, are there any problems with fish deaths? I am thinking about using this chemical but I am scared due to the possibility of losing fish.

Which problem do you have?

Yes it’s safe for marine fish. I’ve used it in my FOWLR. They say it’s safe for corals too but I wouldn’t trust it.

I used it in a tank with fish,sps,lps and zoas for a couple months no issue.

I think most would advise trying to get to the root of whatever problem you're having and fixing it more naturally without using things like algaecides. There's also many more than one kind of algae that persists in marine tanks, and some may be unaffected by that API product.

Can you post a pic of your tank showing the algae you're dealing with, and maybe give us your tank's parameters and I think that would help the R2R community better help you here.

Also know that having algae is a pretty normal thing in a new tank, and most go through a cycle and pass on their own, without much intervention.

Good luck!

I have green surface algae all over my tank. It's a Fowler tank. I only.
Have 5 fish, but they are big ones. I would be heartbroken if I ran into an issue using the algeside.

How old is the tank ? Sump ? Water source ?

Your tank looks good, and parameters are not bad. I love the skull ;)

Do you have any plans to add corals, or is this a fish-only for the foreseeable future? If this is tank will only have fish, you can use a product like Granular Ferric Oxide (GFO) to strip out all the phosphates, which should starve out that algae, and have no negative effect on your fish (they get their phosphate from their food). That's one idea.

Have you tried just cutting the light back, even going dark for a few days to a week? Again, the fish won't mind, but the algae should die back without light.

Have you tried adding some clean up crew snails? They may help keep that in line.

I've never used that API product, so I don't know if it's safe for fish (though I'd bet it is). You could remove the fish and keep them temporarily in something like a large plastic storage tote for the duration of the treatment, then add them back afterwards. Stock tanks from Farm and Garden stores also make great temporary tanks when treating things.

I hope that helps!

Thanks, yes, it is fish only. tank.I am not adding corals, i might put the fish in a holding tank while I treat with the algeside.

Been using it for 2 months on my 25g system to fight off chaetomorpha antennina. It has done a wonderful job and my glass hasn't needed cleaning the whole time. This is good and bad. Good for me but also bad for the snails in my system that rely on algae as food.

None of my fish have had a single issue and all corals are fine as well. I have been doing a half dose though and went super slow. I just recently went to a more aggressive dosing plan to see how it does with bubble algae

Take a look at the GFO option too. It's a good long-term solution for a FOWLR.
