nobody can help? from when i post till now still same colour leh
hi guys, anyone is using the sera co2 test kit?
i just bought 1 at NA 2 days ago.. set-up my tank yesterday and started using it..
i set my co2 BPS at 2. base on the test kit. blue = too much co2, darkgreen = good co2 level and light green = too little co2.
my co2 is dissolved via a ADA beetle replica ceramic diffusor. produces alot of very very fine bubbles. and blown around the tank by my rainbar. i would say 80% of the co2 is successfully diffused.
anyway.. its been half a day upon running this test kit, but the colour was at yellowish greenish colour(same colour as the liquid that was given to drop 3 - 4 drops into the co2 indicator.
so i up my co2 to 3bps. after running for hours.. the colour remained.. i deicded to pour away the current water in the indicator. and redo the test again.
so today, im back from school and i still see yellow colour despite my co2 running 24/7(manual regulator on co2) i decided to once again up my co2 to 4bps.
so from 2+pm till now.. my co2 has been 4bps but the co2 test kit indicator was still at yellowish colour(the 2 photos i provided on top, just taken minutes ago.
i believe my endlers inside the tank helping to cycle the tank was gasping for air..
so now i tuned down my co2 back to 3bps.. is there anything wrong with this test kit? or do i have to wait till the colour change? i check for the expiry date and the closest date for expiry was 02.2012 which is 4years later.
i always thought that sera test kit was one of the best.. but seems like it isn't?
can anyone help? thanks in advance.

Normally blue means too little CO2 and yellow is too much CO2. Your tester label probably telling you that blue need to plus (+) CO2 and Yellow need to minus (-) CO2. Try taking out the tester from the tank it should turn blue after a while.
By the way, you should use water with kH equal to 4 instead of your tank water. There was some discussion on this.

ohhh.. i did'nt know that! anyway.. why should i use kh equal to 4? that means i need to buy kH test kit? omg...
You need DI or distilled water for mixing the baking soda or just get the standard solution via retailers offshore via the web.

hmmm... petergwee.. i don't really understand what you are talking..
anyway.. i'll go get a kH test kit ASAP. so i just use normal tap water.. add some baking soda and test if the kH is 4 then i can use the water for testing my co2 level?
hi guys, went to buy distilled water and API kH test kit today.
my tank's kH turns out to be ~3. so i added little bit of bicarbonated soda and played around with the distilled water till i get kH 4. managed to keep 500ml of kH 4 distilled water.
anyway.. my sera drop checker now is dark green colour. while my co2 is set at 2bps. i think i have to wait for a few hours for the drop checker's colour to stablise?
I think it will took around 6 hours before it is stabilize.
