The grey rocks only left some fragments. Owner said coming maybe in 1-2months time
There weren't many grey rocks but I found some that I really like!! Except that now I'm worry my tank would become too hard and alkaline for my fishes.. I brought vinegar but there weren't much bubbling so I'm guessing that should be fine?
I bought 20kg of rocks and 5kg of gravel for only $15
Thanks for the update! Was it a long walk from the bus stop to the place? That's a really good price! Do post some pics of your loot when free
The walk is insanely long... It's impossible to go there and back by public transport... Yup I will when I'm home!

So here's how all the gigantic boulders are stacked.. I picked those smaller ones and smashed them to the sizes I wanted.

Ignore the toilet bowl but here's my loots! It adds up to about 20kg and the biggest one was in its natural shape while the rest were smashed with a sledge hammer and the power of Thor.
Anyways can someone help me identify what rocks did I just buy? LOL
WOW! 20kg...That is a good buy,just be careful when placing it in the tank
make sure you have enough thickness of sand,gravel or soil. You do not want to
crack the tank before you start..
HAHA wait I can't put the rocks on the tank itself?? And I was thinking of putting styrofoam board below the rocks! Will that affect my fishes?
Dont put the big rock on the tank without any media that can distribute the weight evenly.
Im not sure about styrofoam...
Dude.. Did you carry that to the main road to get a taxi? Hope you dialled a cab! Army training put to good use
Love the huge piece! Nice lines and colours. I'm sure will look awesome once submerged in your tank with lights on!
I went to another LFS at hougang today, $8/kg! Haha.. Guess I got to wait till Dec to try my luck at this "rock farm" as I want the grey ones.

HAHA lucky I still soaking the rocks... Hmmm what about bubble wraps? Are those possible?
And nope I called my mom to fetch me HAHAHAHA
how do you manage to break the stone into smaller pieces. i had a hard time breaking but unsuccessful.
No need lah for all that....just put thick layer of sand and that is it...done...
I used the sledge hammer and swung it over my shoulders with the strength of Thor and the power of Zeus HAHAHA
@AQMS you made me stress HAHA
The vinegar test would usually only fizz if its in direct contact with calcium or limestone surfaces, if it doesn't show the fizzing effect, it just means the rocks is not too calcareous. But the rocks can still have traces of minerals which it will release over a period time. Like what i mentioned earlier, the volume ratio of rocks vs water also matters too.Originally Posted by Ryan Peh
To find out how fast and how much effect the rock could have in your tank, you can soak the rocks in a bucket of water for a week, measure the pH, TDS and GH before and after, then see if there are any noticeable changes. If there are changes, then factor that in when using in your tank. If there are no noticeable changes to the parameters, then the effects will be slow enough not to be of concern.
If the water parameter are only noticeable over a week then I guess there shouldn't be a problem since I'm doing weekly water change of 20-30%?
Use those plastic egg crate/light diffusers to distribute the weight evenly. C328 sells them.
@grandweapon c328 got sell?? What do I tell them!!
Yeah, the week-long soak tests help to find out the speed and extent of water parameter changes, so that you can get a better idea of what to expect and how to manage it during your weekly water change/maintenance routine.
They are outside, next to where they place their rocks and driftwood.
Polyart next door sells them too. IIRC, Polyart has small pieces near the cashier area, and large pieces at the back near the filter medias.
this is how egg crate looks like

think you should buy 1 piece and put at tank bottom...
