bioballs & heater?

If I put my 2 300 watt heaters on the bottom of my sump, if bioballs are on top of them, will they melt?

Thanks

Any particular reason for the bio balls? I really like my lava rocks, and if you put those on top of the heater they would act like passive heat sinks

Mostly because I have bags and bags of them, and trying to save on cost. What does lava rock do? I have never used it before.

Oh sweet!! have to go check that out! lava rock is just super porous rock, acts like bio balls, ceramic rings etc, just bio media. but since its rock it can hold heat and when the heater shuts off they are still giving off heat too. I think a cubic yard or half yard is only like 4 bucks at lowes

Posted mostly info about tank/setup and one picture, I should have my cam, back on Friday as it getting repaired and hope to post more.

hmmm lava rock, that good idea then, maybe I will pick some up and put that in the middle section of my sump and do away with the bioballs in that area.

Yes the bioballs can melt if they contact a heater, especially large ones like you plan.

However, you usually don't want to place the bioballs in the water itself. Typically they are used as part of a trickle filter design. It's very easy to get a length of 1 1/2" to 2" PVC pipe, and cut it into standoffs, about 3 or 4 inches long, and then place a cut sheet of eggcrate on top of the standoffs. That way you got plenty of room for your heaters, and they will cont contact anything.

As for bioballs verses lava rock, both work fine, but have slightly different properties when in use. It depends upon what you want out of the filter system.

It is possible to melt the bio balls if they are in the section where flow is under going up,, if there is enough flow to keep the heater from being hot. Then it wont melt. Times of filter maintenance when the pump is off. U would deff need to unplug the heater
