Weighing down homemade sponge filters

[Lydia]

So I'm making homemade sponge filters for certain tanks...I have found all my materials locally and very reasonable....made filters for $1 a piece! Everthing is great except for weighing it down. Have thought of several solutions but figured I'd ask the forum! Please send me our solutions! Thanks a ton, Lydia

Lead weights

[Lydia]

I thought about taking fishing weights and dipping them in the plasti-coat stuff to make them aqua safe, but was trying to think of something that was usable as is??????

[eklikewhoa]

They use to sell strips of lead to use as plant weights, I've used them before and haven't ever noticed any ill effects.

Another option is to silicone rocks/pebbles to the base.

[Lydia]

Yeah, I saw all the lead strips for plants and all the controversy...... I siliconed stones to bottom of sponge to begin with, but they didn't seem to be heavy enough for the size of sponge. Thought I could find some kind of plastic or vinyl coated weight somewhere without having to do it myself????

Hahaha you're making DIY sponge filters but don't want to make your own coated weights.

fishing string and tie it down

You could attach suction cup to the bottom. If your using bare bottom tanks.

I bought 2 different kinds. One is a huge yellow sponge from Lowes, pure nothing on it, and I cut in half. They are $2. Now I buy big sections of foam from Joann Fabrics. Its even more economical, you can cut in any size/shapel have white, green and black foam!!! I started these for shrimp tanks, now use for fry, guppies, bettas, breeders, etc. Use 1/2 pvc. Pm me if you need more info.
