Best rocks for anchoring

Just curious, what are the best, aquarium safe rocks that people use to anchor down driftwood? How many pounds does it usually take to keep down a medium piece?

I don't use any. I just put a new piece of driftwood in my tank this weekend. I boiled it for about 5 hrs or so and then let it soak for another 24. When I put it in my tank, it sank on its own.

Many use slate. You can drill a hole in the slate and screw it to the driftwood. You can bury the slate in the substrate if you don;t want it to be viewable.

This worked for me, Make sure you use Stainless steel screws.

the only problem with slate, is that unless you place it in the tank before adding substrate, it gets hard to bury it, making it difficult to plant around it (at least ime).

Of course this all depends on the type of driftwood you are using. Some driftwood will float, some wont. My Columbian driftwood just sinks, even if I don't boil it.

Please let us know what type of driftwood you are getting. You may not need to take extreme measures to weigh it down depending on the type you are using.

Has this wood been soaked? Is it new driftwood? You should probably pre-soak it in a plastic tub, or boil it if you have a pot big enough, to let any tannins leech out before you put it in your tank.

Tannins can be easily removed by using Seachem Purigen. That stuff is awesome and works wonders!

Tannins + Purigen = No Tannins

It is driftwood I bought on ebay. It was already pre-boiled and brushed.

It's been soaking for a week and has yet to sink. Not sure of the type.

I just thought of an idea. Why not just take a suction cup, run a sturdy string through it, and then tie that string onto the driftwood. Make sure that you have the correct length in the string. Suction cup to the bottom glass perhaps.

I dunno, it sounds like a "smaller" method to secure driftwood to the bottom. You could also tie a magnet to the suction cup, and suction to the bottom. Tie another magnet into the driftwood and that way you could just stick it together through magnetism. It will also make it easier for you to adjust the position and/or length of the string by just adjusting the string on the second magnet which connects to the driftwood.

I dunno, just a thought....

I actually tried the suction cup method before, to not great results.

The cups didn't really hold on that well. I used several of them for one piece, and if one came uncupped (don't know if that is even a word) then the others would soon too because they couldn't handle the pull.

Trying to re-suction a cup in an established aquarium was almost impossible because you needed a clean surface with the glass. There would always be a piece of gravel that slipped in.

Plus, the metal clasps on the cups soon rusted. Couldn't find any with stainless steel hooks.

How about this.... Use a magnet underneath the tank.....

Sort of like the MagFloat glass cleaner. Tie a string to magnet inside the tank to the driftwood. May even make it easier to reposition the driftwood.

Also, pebbles and other stuff wont really affect the magnet like it would suction cups. I would give this a shot. Of course use more magnets instead of one huge one. You dont want to break the glass underneath the tank.

I think this method may work real well..


Good luck.

New driftwood can leech other things which are more harmful than tannins, and while I agree Purigen is good stuff, and will take impurities out of the water, why risk it?
