w/o realizing its over 2500 posts already... hooray!!!

most co2 indicator will instruct you to use aquarium water to determine the co2 levels. from the colour changes ie blue (high ph) to green (mid ph) to yellow (very low ph), it will give you an indicator of co2 inside the tank.

Now, using aquarium water in the co2 indicator is ok, but less accurate (this is as i understand from much reading on the internet). to use 4dkh water, its a better way of telling the co2 being dissolved inside. reason being that 4dkh is a reference water (think universal where everyone is having same 4dkh water) while your tank water has got different ph compared to other people's tank. in fact, by adding the indicator solution + tank water, u r just saying your current tank's ph is so and so range, when the co2 is turned on, i should get to the yellow-green range to get the 30ppm target...
*please correct me if its inaccurate*

also, to make it clear, it is an indicator only. its not super accurate. it takes roughly 1-2 hours to get the colour changes. the tell tale sign is to look at your fishes. if they are breathing heavily + on the surface, its too much co2!! this can happen even though your indicator is still in the green level...

personally, my indicator has always been dark yellow. it does go to bright yellow at some stage but my fishes are still happy with it.

look for kiminha's explanation on why there should be 2x co2 indicator using different dkh solutions. u will get a more accurate reading of co2 in your tank.

btw, dun get confused between tank's ph and the co2 indicator's ph. adjusting the tank's ph does not give you co2! injecting co2 and change your tank's ph using other methods are 2 different things!

cheers.

oh, over 2500 posts, who wanna do v12?

nice info! thanks for sharing mate.

Well, the thread has reached its limit. Better to sit down and spam in newly created thread

Someone please create V12.
Please copy the information from first page of V10. This version front page is not complete.

Please do your work nicely if you want to host this topic. Lets gather all information for planted tank and share among all members !

I think the next thread should have proper image linking and a more detail guide on aquarium cycling.

Has anybody ever bought fish from pets lover centre in ikano? They have new batches of fry of most fish but Ive never had any experiences with them.

I'm abit skeptical because the other day I was looking for tweezers at the herp/reptile section and I saw the feeder mice eating one of their own in plain view of children. Like 5 mouse cannibalising on the corpse of a sibling, blood everywhere and stuff like that and i was like nope.

so yeah they kinda suck in their reptile section.

Or am I better off somewhere else?

Are you referring to their services or the quality of the fishes they selling there?

Quality of livestock. Large petshop services are.. well, they are a business so can't expect much more from there.

well, most of us see from LFS and then read up then seek advise (from LFS n counter check online) then only purchase. yes, they have a business to run but again there are responsible business people too.

best you get yourself equipped with info that you need.

My LFS, the only healthy fish they have is arowanas and kois and the plants. Yes they are cheap, but they are also very oldskool if you know what I mean. Ive checked out most of their other fish and they don't look healthy. So i'm looking around.

My messy 2ft tank.
Riccia here and there kinda messy ...

Damn overstocked bro

V12 is launch. please close this version.
