One 3 inch the other 4. Is it overcrowded?

Some questions on green water.

My water has turned green, not very intense (still can see my fishy clearly). My aquarium pharmaceutical ammonia test kit show high  level, between 4 to 8 ppm. Is this normal? Also my green water is in the initial stage, i should contine to keep the PL light on right?

If the answer to the above questions is available somewhere pls refer.

Thanx in advance.

Give u a hint ... I keep 2 2" demekin in a 3ft guppy tub filled full to the top, about 90L per fish. U think your 2ft tank 50L can keep how many ? My standard ratio of keeping goldfish is a minimum of 50L per fish of not more than 3". Anything bigger will have 80L min up to 250L each.

when did u test your ammonia ? before light on or a few hours after light on ? Also I am not too sure this test kit is good enough to test. HB, what brand u recommend har ?

Since it is in the initial stage of green water, probably u turn on the light longer up to 12 hours for the time being. When established, then switch to 8 hours. Your PL lamp above 50watt ? Anyway, is it a normal 2x1x1 tank ? or something bigger ?

errhemm..... allow me to share my experience.

I used to have a 80~90L toyoga tub. I have a 2x55W osram switched on frm 8am to 6pm. Feeding was something like 3 x 2 clicks of the autofeeder. There are 2 3~4" ranchus in it. Water change is once a week. To test for ammonia, I have the Seachem ammonia alert.

The ammonia level would rise to "alert" level in the 1st 3 days. towards the end of the week, the level would drop to safe. The green would be very intense. My fish would get O2 burn.

So 110W of PL light, with around 40L per fish doesn't seem to be good enough leh.

Really envy u have such big space just for green water. May i ask what is the size of the tank u used for viewing?

From yr infomation, thats mean w/ my 50L tank the most i could hse only one 3 inches ranchu.

I did the ammonia test a few hrs after turning the light on.

I try to keep the light on for around 12 hrs a day.

PL: Enqing brand, double white tube, should be 55W.

I think HB mentioned before JBL test kit could measure green water ammonia level. (Correct me if im wrong)

One more thing if i continue to hse my 2 ranchu in the 50L tank and wait upon the green water get more intense and conduct more regular water change of say 50%(HB recommend 90% water chage per week in one of the stickly post), would that be better?

For green water, there's only one kit I know of that works. Why? Most of the test kits are single colour based, ie, you check the result against a colour chart. But since green water is green in tint (instead of clear) to begin with, your result will not tele with the chart at all. ohmy.gif

It works for other coloured water too... such as black water often used by Arowana keepers.

I dun use PL, paisey, can't help much.

My viewing tank is a bare 4ft tank with a sponge filter. dun even hv a light on it. shiok.gif

If u wanted to, you may change as much as we do. I change 80-90% weekly too. Sometime 100% depends on situation.

It's not about how you could duplicate those written efforts, look at your fish, setup, every detail and adjust accordingly. Take your time.

Seeding 50% seems like a lot to me.

I'm sorry I haven't been following your setup but you mentioned your green don't get intense enough. The problem could be two fold. First, your lighting could be too weak. You said you have a 2 feet tank with 50 litres. So I'm guessing the distance from the lamp to the tank's floor is at least 1 ft? What you can do to intensify the output is placing the lamp at the base of the front glass wall. This way, the light is merely millimeters away from your water. I don't know if your goldfish will go blind becoz the "sun" is now beaming light directly into the eyes though. biggrin.gif But my experience with this method in a fries tank was okay.

Secondly, it could be due to low ammonia. Did you feed your fish? green water needs ammonia to get started and get intense!

So overcome the above first. You should find in a proper setup, the water will turn relatively green by 2nd day and intensely green within a week.

low ammonia? readings looks high to me unsure.gif

you could try 60-70% change every 4-5 days, then adjust accordingly to find what is suitable for your setup

as matrix said.. test and adjust accordingly to find out whats suitable for your setup

no need to achieve intense green until u can't see the fish at all to change water biggrin.gif

recommended would be 50-60l per fishy

if you're serious with green water usage, you could consider getting a 3ft guppy tub with a 150W 6500K MH, can house 3-4 fishy biggrin.gif

meanwhile u could consider a 50% change..

Thank all bro for the comments and suggestions.

My 2 goldfish is still doing ok (at least no physical illness) in the 2 feet green water tank.

Guess i still need to make some adjustments to my setup before seeing any positive results.

Bro HB, why 50 percent of seeding is too much?

One more thing, why the recommendation of 50-60litres of green water/ Goldfish? I thought the nitrite and nitrate would be presumely zero, so why do i still need such amount of green water per goldfish?

Pardon me for my ignorant if i miss any important points.

Most outdoor green water needs no more than 5% of old green water to seed. Seeding more means the green water will get intensely green too quickly requiring more than one water change a week.

There's no nirite and nitrate in green water.

The recommendation is becoz green water isn't as efficient per se compared to bio-filtration in converting ammonia. tongue.gif

so what happens in an overcrowded tub where ammonia is skyrocketing with 5% seed? adapt accordingly to situations, there issn't a hard and fast rule

I hope it is understood that forum's postings are not personal advises tailored to individual setup. Too many factors are involved; hard and fast rules hence are okay but it's up to yourself to explore deeper.

Coming back to answer your question... it would be best to tackle the problem of overcrowding to begin with. mad3.gif Like I said earlier, green water isn't as efficient as bio-filtration; over-crowding is suicidal.
