Algae from feeding corals

Algae from feeding corals

How do you guys deal with this? The day after I feed my corals my sand is covered with algae. I can siphon out but then happens again. I run GFO and algae was under control until I started feeding.
So any advice?
Here are some pictures. It clumps together. Was going to stir up sand.

Thanks!

 

What are the members of your clean up crew?

 

100g tank
1 fire shrimp
7 hermit crabs
8-10 Nassarius snails (not sure on total as some hermit crabs are now wears some snail shells)
5 Turbo snails

 

had a slepper goby but LTA ate it. Then had a watchmen goby die in overflow. I cant keep them alive.
But is it common to get algae after introducing coral food?

 

What we need next are nitrate and phosphate levels.
How long are your lights on for during the photoperiod?
What specifically are you feeding the corals?
How old is the tank, if I remember it's fairly young.

Yes if you are introducing too many nutrients you'll running into an algae issue. If you're using a frozen food rinse it first before introduction to tank. Cut back on amount of food, reduce photoperiod are all inteventions you can try.

 

if this makes you feel any better, that really doesn't look to be much algae (I can show you algae lol)...I'm sure it's not due to the feeding per se but the extra nutrients the additional feeding adds.

 

To me looks like diatoms algae. It clumps up if try to move it.

I leave lights on during work hours. So 6-8 hours. Then moon light from 6-9 and then off. Give or take.
i do that since clams need the light but now also my corals.
Dont test for Phos but Alk is 10 and Mag is 1250. Nitrates 0-5.
Tank is 11 months old. I only have this problem after I feed corals. I use this.


Part of me wants to stop feeding the corals. Most will be fine but rate of growth will be slower. And switch to mysis shrimp for feeding. I use that anyway.

 

Ha I bet!
I hate algae. I run GFO. I think it's diatom algae. How do I stop that?
I use a syringe I got from cvs. Barely use any food. But somehow seems to mess up the system

 

Thanks for helping me

 

Of it clumps, it's probably cyano. I find that cyano on the sand bed seems to go deep under the sand. I try to vacuum it all up, even if I take some of the sand with it.
