this is for saltwater i guess then? I would think they would need to be changed out alot more frequently then u think. but idk maybe it will work....
heyty for the info on the fishDMWave45 said:I would say it was a waste of time personally. You would probably have to change the ice packs out every ten minutes to have any real effect, and even then I would say the temp. drop would be minimal. I would just use that filter on the tank normally for extra filtration. Also, your fish are mbuna and you have several of the very most agressive species. Watch out as they mature because it may turn into an all out war.
