Brew Green Water In A 2ft Tank Options

[HappyBuddha]

Plus, I had to remove the green water because it started to smell too.  I don't like the smell for indoors.

I have a green water tub in my airconditioned room and there's no smell, or very little of it. In fact, the clear water tank in another room is actually more smelly (in the usual aquarium tank kind of odour.) If you think about, it shouldn't smell at all if the green water is in good condition.

How often do you change the green water? I change mine once a week without fail. The longest I could stretch was 10 days. It was way too intense and starting to smell like a clear water aquarium. I have to change it and not push my luck any further.

yes, i think we can safely say that once the green water starts to turn brown/smell bad, the fish is either sick or the algae are dying/decomposing

None of my tanks have any smell at all. They are perfectly cycled. The only time they smell is when I do water changes. Then the algae in the glass is exposed to air... algae smell.

The green water indoors starts to smell like algae invasion. I don't like it. Maybe it was too green. I always do at least a 40% water change every week for all my tanks and ponds.

after 3 attempts, finally succeed in brewing green water. i know algae boom after seeing algae spots on sides and bottom of the tank.

water stinks cos of high ammonia level and decomposed particles. ranchu breathing heavily near the surface of water and seems to be trying to jump out of the water. so i transfer it back into the big tank and switch on PL lights for 12hrs. next morning water turn green.

After work on the same day, i cleaned up the algae spots and change 65-70% of water. again i switch on the PL lights for 24hrs this time, water turn virgin green and does not stinks.

Tested PH level around 8.0, almost the same as the big tank and transfer the 4" ranchu into green water tank. Did the same, switch on PL lights for 12hrs.

Second and third day after transfer the ranchu, green water turned darker green each day. Four day it's so dark that i can't even see it unless it's swimming towards the sides of the tank.

Feed it with lots of pellets and switch on PL lights for 12hrs after that. This is the seventh day, green water doesn't stinks although it's very dark green in colour. Ranchu not breathing heavily anymore. Going to change 90% of water next time.

Woo hoo!

Congrats man.

So why do you think you finally succeeded in your forth attempts? You seem to imply it's the long hours of lighting? On the other hand, you also seem to imply you actually kept the high ammonia level in check by removing your ranchus?

BTW, why is the pH of your main tank, presumbly a clear water tank, so high at 8.0?

It's been two weeks since you successfully cultivate your green water.

How is it now? Are you having any problem with it?

hi all,

i've been trying out green water since the start of dec 03. my set up is as follows.

-2x2x12" 10mm tank
-1 no of 55w 6500K pl
-1 no of 55w 12000K pl
-both the above pl is in 1 casing. 12k pl turned on only 2 days to kick start the green water.
-1 no 2260 ehiem pump to spray bar all four sides of tank. bar is 1.5" above water
-no filter.
-water level only 10".

stocking level. (incl tails)
2 pcs r/w short tailed rhukin 5"
2 pcs r/w buffalo head ranchu 3.5"
5 pcs r/w and red ranchu ranging from 2.5" to 4"

-pH 7.6(start of wk) to pH 7.8(end of wk) buffer with 1 Tbspn bicarbonate/wk
-green water kicks in the 2nd day(mon). by the 4th day(thurs) i can hardly see the goldfish from the top. smell is only evident on day 1 & 2 and disappears from the 3rd day onwards.

BUT, i've noticed that during the end of the wk on the 5th or 6th day onwards, the goldfish tends to have red spots on the under belly, from below the cheeks onwards towards the anal fin. can someone kindly advise what is this sign linking to. i find that changing the water 100% and seeding 2 litres back helps to stall the problem, than it starts again for the next week.

what am i doing wrong? i also see that the color is starting to "crack" and it starts to be "speckled" and not full as when i bought it. in fact the red color is giving way to orange.

kindly advise. many thanks.

regards,
tm

Your bioload seems abit high doesn't it ? Maybe u might want to take pH and Ammonia reading, then Nitrite and Nitrate for comfirmation that they don't exist.

way way way overstocked..

hi all, 
 
i've been trying out green water since the start of dec 03. my set up is as follows.... 

This is a long reply.

I'm glad you documented your setup. It sounds just like my desktop green water tub except both my of PL lamps are 7000 Kelvin only (and I also turn on the 2nd one only on day 1 & 2).

At 10 inches water height, that's 94 litres. I feel that you're overcrowding the tank. The ammonia load may be way too high for the green water to process. The redness you're experiencing could be ammonia poisoning.

I'm amazed that your PL is able to cultivate green water when the depth it has to penetrate is massive 10 inches. But you mentioned you have installed a pump that circulate the water. That could be the reason why the PL is able to cultivate the algae; the pump actually brought them up to get light. Amazing discovery for me!

I would suggest shortening your water change interval from 1 week to 4-5 days max. This should keep the ammonia level low. By right with green water, the ammonia level should be nil but since you're overstocking the tank, at least try to keep it low. The best way is, of course, to reduce the stock load. Overcrowding clear water is bad (unless you know how to keep the water parameters in check). Overcrowding green water is suicidal.

I don't understand what you mean by the colour is starting to crack. But I notice the pH averages 7.7. That's like... clear water kind of pH. One benefit of green water is the pH will be high, typically mid 8 (some even claims theirs hit 10!) The high pH protects the slime coat, which in turn not only make the fish less susceptible to diseases but a healthy shine as well. Maybe you want to consider using more BS to boost your tank's pH (and hence kH)?

2 pcs r/w short tailed rhukin 5"
2 pcs r/w buffalo head ranchu 3.5"
5 pcs r/w and red ranchu ranging from 2.5" to 4"

my goodness, my green water holds roughly the same volume as yours, and i only put in 2 3+ inch ranchu. and ammonia could easily go into warning on the Seachem Ammonia Alert if i am not careful.

or put it this way. i wouldn't even put 9 goldfish in a 100L FILTERED tank, let alone a greenwater tub which has a far lower stocking ratio than a filtered system.

hehe.. someone tell that to my dad.. he made me to setup a 100L filtered tank with 7 gfs in it
using 4 sponge filters and still having problems keeping the parameters in check..

Hows the FBF experiment going?

wahahaha, it's not that i don't want, just that having such a high stocking ratio makes maintaining it a pain in the a**. rather save myself from the trouble

the FBF thingy is not working as i expected such it's a super filter, but it isn't reducing nitrate like the way i want it to be. maybe it's because the main occupant in the 3ft tank is a 13" aro, and when the poo comes out it is a big amount at once...

but i think it removes ammonia darn fast, and i can probably stock the tank way higher than usual.

[CyberET]

interesting
because i'm considering using a FBF to supplement the sponge filter..
hmm..

hi all,

to all the sifus out there, a great thank you!

dennis - i will test the water on sunday before i change the water, than parameters will be be at its worst.

cyberet - noted your observation. will look into splitting the stock into another tub.

hb - noted your diagonsis. will chk the ammonia level tonight when i get home. the pump is mainly to aerate the tank. even though i've got a rena 2 outlet air pump running in the tank. so bubbling is constant. as the water evaporates slowly, the spray becomes very strong producing even more bubbles. the light penetrates the glass tank easily. i can tell that from the side of the tank. at every water change i put in 1 Tbspn of soda bicarbonate to buffer the pH. highest it has gone to is pH7.98 or .99, never hitting pH8.0. I've got a electronic pH controller hooked onto my aro tanks, so it is just a matter to transfering the probe to the goldfish tank.
the "cracking" looks like.....how do i describe it?. the head of the goldfish is rough and undulating with ridges and valleys right? what is happening is, in the valleys the color is lighter and the color at the ridges and plateaus are darker, at times speckled red, yes red spots! so to me it looks like a crackled surface. it is not as when i got it, with it full solid color. kindly advise. a visit to my place in marsiling by any of the sifus would be very much appreciated.

square_guy - noted the stock number. thanks for the SHOCK........only 2 3"+ goldfish.

i will monitor the situation.

i've got a toyogo tub, think the dimensions are 24x16x12". will set that up to hold the smaller 5 ranchus ranging from 2.5" to 3.5" inc tails. that tub has a diy toyogo tub ohf holding 250 bioballs; with a 20+ litre capcity. water level on the ohf is only 3.5" of which half is filled with blue green biomat.

comments and advise please.

THANKS guys!!
