Excess Nori

[Bartman]

I was just wondering; will excess nori pollute your tank like other foods? It's just seaweed but I know my fish don't eat it all before it ends up getting blown around the tank.

Give them less nori &/or less often. Yes, any uneaten food will pollute your tank.

If you aren't folding it up a lot before clipping it, try that. It will keep it together longer and give them a chance to eat it slowly.

I find my tangs tend to eat a fair amount at first but then leave some, which ends up floating about the tank. During the day the go and graze it until it is all gone. So I don't find that a bit of nori floating in the tank really pollutes it as it does get eaten throughout the day. Just my opinion.

I've always gone by the rule that it is always better to feed too little rather than too much.

It would be better if all the nori was eaten, as suggested go smaller amounts of nori. You could try smaller amounts more often, they might eat more that way too.

It also depends on you system, to me some left over nori isn't going to cause a problem, but in smaller systems with smaller skimmers, no fugesetc, over time it might contribute enough waste to cause undesireable algae blooms.
