I was wondering if these rocks are safe for aquarium? I mean that the rocks might have chemicals? Sorry for being such a noob because I have a 5ft tank and those rocks just look tasty......

So far i have used their grey rocks and black lava rocks in various tanks (including shrimp tanks), no significant issues encountered so far.

The black lava rocks seem to be mostly inert, no measurable effect on parameters.

The grey rocks do release some minerals though, so the tank GH will naturally increase slowly over time.

But do note that i wash, scrub and then soak all the rocks in a bucket for 1-2 weeks before usage (doing multiple water changes and testing the TDS). So that helps to remove the majority of residual stuff that might be on the rocks.

For other types of rocks, i guess you'll just have to test and see.

Had purchased several kgs of grey stone and found out to be too big for my 2ft tank. anyone has any ideas on how to break into smaller pieces? What are the most effective methods? Had tried using hammer but nothing happens.

You need a much bigger hammer and more muscles, aka the Might of Thor.

As what you've seen in the first post...



There is a reason why the rock distributor has a large sledge hammer at the rock pile (not a small tool hammer). You need the extra mass and weight of a large hammer to smash the rocks into smaller pieces for packing.

Hi guys, just to let you guys know, when you're going to Jalan Lekar to buy rocks, remember to bring alone your own sledge hammer. Last time I went (about 3 weeks ago), there isn't any hammer around. Luckily, I met 2 uncle, they brought along a sledge hammer. End up I got to borrow it from them to smash the rocks. And I got a tip from them on how to smash the rock, when smashing the rock, use the sharp part of the hammer head (the part between the front and the side, sorry can't really describe) to hit the rock, it will be much easier.

I was thinking whether any aquarium shop in Singapore have the big hammer that can be borrowed to smash the big rocks.

anyone have been to this place recently? As I intend to go there see see look look for some dark grey rocks with light/white strips for my 90cm...

Just went to this place abt 2 weeks back. Was looking for black lava rocks and bought eventually 15kg of it. Just to share, I paid $1/kg. It is no longer the 60-70cents per kg pricing. Not so sure about the pricing for other rocks as I did not ask. That said, even with the slight increase, I'm not complaining as its still a very small fraction as compared to those of LFS.

[Urban Aquaria]

Yeah, they don't sell smaller quantities at the lower bulk price per kg anymore, the price is higher if you buy in loose pieces.

It's only if you go for the 25kg bags which cost $15, then it works out to around 60 cents per kg.

Big hammer is one thing. Are there any big dogs around his vicinity??

Dropped by here recently, just to update, there are tons of black lava rocks most likely just shipped in. As for Marine rocks I did see some in the shelter with the coral chip looking rocks

Hi UA, for those grey rocks u bought, do they still have bubbles when in contact with vinegar after several wash? Read about the vinegar test method. If there are bubbles does that mean definitely not suitable for shrimps (not high end type but fire red)? Or still ok? For gh increase, I assume weekly water change should help? Thanks!
