Fertilizer Ice cubes?

Odd idea:

Anyone ever think about premixing a dry fertilizer mix with water and then freezing them as ice cubes for easy dispensing? I realize that dry fertilizers can only be mixed ahead of time in limited quantities because stuff will begin to grow in them.

I doubt a single ice cube would lower aquarium temperature by that much.

Any thoughts?

It would work, but I really don't think that it would be worth the time and effort.

I think it would be worth it if you were to go out of town and had someone looking after your tanks. When I leave for a while, I have to pre-measure everything, because everyone over feeds when they watch aquariums.

So I think if you could just tell the person to drop in a cube every second day, it would be an excellent idea.

Is Hokey Pokey Really What It's all about ?

Make sure you have that ice tray marked and that it can be easily differentiated in case you have company at your house (so they don't get any nasty surprises in their cold drinks, LOL).

it's pretty likely that the dry inmgredients would come out of solution when the water freezes, don't you think?

I've suggested this for "soil mud cubes" for many years now.

Ferts will work, not sure what you hope to gain from it, the ferts will diffuse into the water column rapidly.

They always do.
Plants roots will leach them as well.
Plenty of experimental evidence shows this.

Soil is bound and slowly breaks down over time and tends to hold better, more organic matter is prefereable.

It's also......"dirt" cheap.
