Aquarium putty

[PaulVerrall]

Any recommendations? Must be able to use on wet rock and set quite quickly.
Fed up of rearranging my rocks every water change, so want to build a few structures.
Super glue no good as I have lava rocks and not enough surface area for glue.

I used brown HA6 silicone when I made my lava rock structures a few years ago (2016) when I had the Roma 240.
I must admit that I made them outside the aquarium.
Here's a couple of pics



All the best

Cheers mate, that's exactly what I want to do, just on a larger scale but was hoping to do it without killing all the bacteria on my rocks.

Handy stuff! My mate bought me some recently to help with the warhammer models (posing/adding scenery) we’ve been painting

Got some coming tomorrow, using superglue at the moment with limited success

I will warn you @PaulVerrall that Milliput sets white in colour.

A better but more expensive choice would be D-D Aquarium Solutions Aquascape Epoxy. It's far more pliable, becomes semi hard in 3-4 hours, fully cured in 12 hours and comes in different colours.

I bought the black one, from what I read it sets a grey colour which wouldn't be too bad, I'm going to try and hide it as I have big rocks anyhow

Miliput also comes in different colours, soft, fine etc, and half the price for the same product.
