Prawn in the fish tank for cycling

[Yellowbelly]

Hi All

Since I can't get the guy I need advise from, I have to place it here for some expert here to help

I have place a dead prawn into my tank for cycling yesterday, but when I have a look at it just now in the tank it looks like a little bit cook to me after I have remove the shell?????

Should I remove the prawn ?

Stange eh

[Terryz_]

It is normal..

[blacknails]

Yup... Prawns that have been dead for some time will turn orange/red... wonder why is that ah?

[terryansimon]

yah mine also. feel damn tempted to eat it now.

[Yellowbelly]

Man, it makes my water stank a bit anyway to remove the smell ?

Saw someone use ambipure or something before.. hehee...

Just bear with it, no way to get rid of smell one... ventilate the room more loh

[Yellowbelly]

Ok , thanks.

Wonder why need to put a dead prawn in the sub tank?

Can we put it when the tank already stable?

Need your guy's advise thanks?

[blacknails]

Huh? Putting dead market prawn in a stable tank? That would screw up the water conditions and cause danger to all the LS!!

The whole idea of the prawn is to introduce some form of nitrogen and carbon into the tank by decomposition to start of the cycling process. It need not be prawn. Fish food, squid, urine, etc can be used. I think a small prawn for a 4' and more is just right. Smaller tanks should use half a prawn or something less to prevent the water turning anaerobic due to the bacteria bloom. Always prevent good aeration during cycling to reduce the foul smell of hydrogen sulphide.

ic thanks......good knowledge.....

[terryansimon]

Tanzy. for my tank, I threw in two prawns. is that an overkill? =\

Hi,

no need big size pawm,

small shrimp will do. (1cm or less type)

[terryansimon]

uh-oh. think I'll remove one of the prawns tomorrow. mine looks pretty big.

[blacknails]

Oh we can use urine? Aren't there other harmful chemicals in urine besides ammonia?

[Yellowbelly]

I threw in a Tiger Prawn too big for a 3ft tank ?

By now I am seeing a layer of some kind of whitish slime covering the body already. yuck

huh? wad shrimp/prawn to use for cycling the tank? those frm market and we eat one ar? dead one? or can we use those selling in LFS alive ones tat for feeding Luohans and arowana?

[Terryz_]

I jus put a bag of $1 feeder shrimp to my two ft tank to start tht process...

[aStRoBo|]

den put till when? till they die or wad?

[Terryz_]

Till they die and rot and disappear..

I just took out the prawn and the whole flesh just slipped out of the shell I have to use a net to sweep the water for it "exploded flesh "

Don't bother lah yellowbelly. When i cycle my 3.5 ft tank i think i threw in about 8 prawns not knowing it's too much. still ok in the end. cycling took 3 weeks. make sure you have sufficient live rocks and your water circulation is good

[SBS_Transit]

while cycling the tank with prawns, do we need to put in LR, on the filter,protein skinner and power head ????

[terryansimon]

of course the liverocks must be in there. if not, where will the beneficial bacteria come from.

some people don't recommend the usage of a Protein Skimmer, but I turned mine on nonetheless because mine is semi-cured liverocks. there are still living organisms in that darn thing, and probably waste will be generated. so its running for now.

powerhead for water circulation is a must if you do not have a return system from sump or a close loop.

Hi

thanks I currently have about 17kg of lr inside there and how do you determine whether your water circulation is good ?
