No CO2 for a few days?

[szesteve]

Would like to know if it's okay if my tank goes without CO2 for about 3-4 days when I top up my cylinder?

Also, how long will a 2 litre cylinder last at 5bps at and average of 8 hrs a day?

[tawauboy]

why not go to a lfs that provide on the spot co2 top up?
bioplast is one of them.

if you have to go without co2, it may be better to reduce lighting and fertilization.

if you're running your tank at 5 bps, I would really advise you to get a bigger tank... its much more economical this way.

Not only it economical but less troublesome too. Go to Bioplast (refer to lfs list). They do on the spot top up. Anyway, 3~4 days without co2 is not the end of the world. If you're worried you can actually prepare a DIY set just to pull thru the time. Try using lots of yeast to give it a strong production rate. Afterall, this is juz a temp till you get back the co2 tank.

Hmmm...u mean bioplast does it on the spot???

I didn't know that....well, i guess that really does solve my problem. I really don't wanna buy another cylinder lah...hiaks...

Thanx guys.

Oh, one more thing. Would it be an overkill to run a 2026 and a 2224 filter for a 4 x 2 x 1.5 ft tank?

[sherchoo]

steve,
I think a 2026 is enuff at the mo..... if you have heavy bioload then go for the extra 2224.

[szesteve]

Sherwin, what do u define as a heavy bioload?

I'm looking at 100 malayan shrimps, 60+ cardinal tetras and about 5-10 algae eaters like ottos and SAEs.

bioload = amount of fish/tank size
you've only told us your amount of fish
i doubt anyone can tell if you're overloading

fwiw, my 4ft tank has 1 discus, 4 keyhole cichlids, 60 odd cories iirc, 80+ cardinals, currently 100+ malayan and 50+ yamatos
i feel it's at the bursting point
but water conditions are A-ok, so i'm not perturbed
nevertheless i still would want to do water changes

so...
how big's your tank?

4 ft x 2ft x 1.5ft.
He mentioned in the earlier post.

Your bioload is okay.

[szesteve]

thanx.

Btw, why do so many ppl like to put corydoras in their tanks?

Is it adviseable? What's their role actually?

[Allen_1971]

Well many people find the corydorus "cute". Also, they come in many varients. In addition, they are bottom feeders, so they help pick up whatever food gets missed.

[coryfav]

corydoras are sooooo cute, that if you're to keep at least 6 of EVERY types that's available in s'pore alone, the chances of overloading your tank will be quite high! []

yimin, after seeing your bioload, i can consider my own 4ft 'ok' now. [] and i've only 12 types with some less than 6.

[stormhawk]

coryfav, i either keep a pair or a trio of any cory species i can find. don't wanna overload my tank.

[eprouve]

Incidentally on the topic of Coryduras... does that small bumble bee (very striking yellow/black fish scientifically know as Brachygobius xanthozona) belong to the coryduras family?

[DEA]

corydoras is the family name, not the common name
ergo, brachygobius doriae doesn't belong

[sherchoo]

Eprouve,

It's a type of goby which requires brackish water conditions.

[szesteve]

Okay,

But won't corydoras eat plants? Or mess up the gravel and plants?

[DEA]

apparently not
mine are very tame
some say in the beginning stages of planting they'll uproot plants
I find that so long as you place the plants correctly the plants will stay exactly where you put them
