really? consider cheap la right? haha

is this the one http://www.drsfostersmith.com/product/prod...fm?pcatid=10109?
does not look like it has any 'crontol'thinggie to control co2 also.. :/ lol im so clueless

that one is checkvalve...u need that also..cost 1.50-2.00 each...there is another one called air control valve..look like this...

YES.....This thing can be found any LFS, e.g. EA, 88pets

owh.. okay okay cool all less than rm 5

hope when i start co2, my soon to be added shrimps & otto wont suffer

erhm.. pardon me, but control valve really need meh? the diy might explode leh... if the pressure reach too high...

cut on sugar amount.

if u want to control the co2 u have to have it..but i used to let it go half..not leakage so far..

oh.. i went without the control valve and no check valve. coz i find these 2 impede the co2 flow into the tank. even if backflow occurs, the tank will fill up the co2 bottle only. it wun spill over.

anyway, tats wat i did la... maybe a bit different experience.. hehe

You need check valve and control valve with 2 output.

One is connected to the diffuser
Another one is not connected to anything.

So you open the control valve that is connected to the diffuser in the morning.
At night you close that and open the other valve to let the air out.

Simple.

Valve actually have many many type. Plastic one can use for DIY co2, bcoz less pressure.
Normal ppl will buy metal one for co2 tank

thanks guys. learnt a lot today. haha..

here is a very good place to leran things, especially for new kaki

Today I saw a disposable CO2 system for like RM140. The refills were like RM20+. Normal price?

http://www.paraquatics.co.uk/contents/media/l_mc086.jpg

why dont u get one full set co2 tank , maybe get 2nd hand much cheaper. normally 3kg refill only rm 20 can last for 3ft tank min 6 months

ya i agree with derick, and if you are serious about planted tank, get a proper one, not those disposable type which cant last you very long.

yes, RM20 for refill is kinda normal depending on where you go, if you go to syarikat city in Sungai Besi, then you can get your tank refilled cheaper.

the co2 system as per your photo is really too small for me... but in your nano tank, I'm not too sure about it, but I think RM140, can get a decent 2nd hand 3kg tank easily like derick said. but without the manual regulator....

aaa i wanna that real co2 system + real good light + real filter too

Yea real co2 is good.
You should get it.

Im saving allocating my war funds for aros now.

Syafiq!
That day 1 snail only right? I just check like 5 mins ago and i taken out 7 snails already!
And 1 pair sumore having xxx there.
They sure do multiply fast!

i read and some said if i want less co2, add sugar, some said reduce yeast..
the valve and check valve, many opinions..

so i just plan to do it like this http://www.my-mac.net/forum/viewtopic.php?f=13&t=11047

now, im still not sure if i need check valve cause he does not have it.. but having one to open at night makes sense too..

also, since my tank is so tiny, 22x16x15cm & lacking of space, which type of diffuser/reactor should i use? the glass kind of diffuser? or DIY reactor

girls are just bad at these kinda things. LOL

Today is a sad day.

My gf's puffer named Puffi died.
He was okay this morning but he passed on.

Feel real sad coz we always go look for ghost shrimps or went catching some longkang fish for him to eat.

The little fella was a smart one too. We would often use a small green net to catch the feeder fish or shrimp and he swim into the net to eat them.
Eventually, he gotten used to the routine until everytime he saw us he would follow us around form inside the tank.

So RIP little one. Hope you have a better life in Fish Heaven.
We will always miss you~

mini puffers are cute
