水草情迷

Hi Bros,

Any suggestion for me...
Want to DIY a lamp for my tank (180L)
would like to use T5 or T5HO with 50W & 6,500K...
thanks

180L.. 個缸既呎吋即係幾多喎... 好高又得, 好寬又得, 好鬼長又得.!?

Hi Grass Man,

My tank is about 50" (L) x 22" (D) x 12" (H), i use it to keep gold fish...

any suggestion , i want to use high watt lamp to produce "green water"

Any suggestions bros

I currently using a chinese made lamp with 2x 30W 6,700K T8 - case 48" (L), tube 36" (L),
and I want to amend it by using T5...

wow, nice board on top, hwo much u pay for that? is it from FS? it's so expensive...

Hi Chowdee,

the top board is 亞加力膠, about $150 (about 5mm thick)
i bought it in shau kei wan, the food timer holder is about $20...

點解 d 水可以綠到咁既...
入面 d 蘭壽有無問題 -0-"

This is the way of using green water to keep japanese ranchu. In general, Japanese breeders also use this way to keep ranchu.

Green water help to enhance the color development as well as the head development. A very good way of keeping to all kind of gold fish.

However, it is hardly for me to see the fish when the water become intensely green (normally, it takes 10 days to create intensely green water when i using 2 x 30W 6,500K tube, that's way i want to use T5HO with a higher watt output), and I used to take them out to check their health when I change water once a week

see one of my japanese ranchu development with green water keeping

so, any suggestion on DIY T5 Lamp for me, please advise

I am very glad to know such a "BIG" "C" in Goldfish in hong kong.
I believe It is also very clever to use a shadow tank for ranchu.
Green water is also the best for the most difficult goldfish "Butterfly tails". Did you try it? I have a very failure experience on this.

Hi Alder,

I'm not the "BIG" "C" that you mentioned la, just a goldfish lover in HK, learned & gained experiences from others. Have learnt using green water keeping from my friend about 10 months and found that it is very very powerful (as u can see from the picture), there's still a lot to improve because i keep the GW by using indoor lamp instead of direct sunlight...

i used GW for Japanese Ranchu only, never tried Butterfly Tails B4, guess it is the same way la...

here's a singapore website that you may find more interesting info about GW keeping at both INDOOR & OUTDOOR environment

Back to my problem, any brothers would like to give me a helping hand

checked the info. of philips regarding the T5 & T5HO...
guess i'll go for the T5HO because it provide more power in terms of Watt output as well as the length of the lamp tube suit my old case , cannot use 54W lamp tube cos it's too long

i will go for...
- 2x 39W, 6500K
- an electric ballast (checked that there's a 2x TL5 24/39W)
- 4x lamp tube...
- some wire...

BUT, I DON'T KNOW HOW TO CONNECT ALL THESE THINGS PROBABLY, especially the wires set up, PLEASE HELP

Hi iso712003.

Are those goldfishes yours?
It seems that they are with very good potential.
Where did you find such a high potential goldfishes in Hong Kong?
It seems to me that you can only find not very bad adult goldfishes but seldom find acceptable small one.

You already start it with good methodlodgies. I find that the optimal height of tanks for top viewed goldfishes such as butterfly tails, ranchu, etc are 8 inches to 14 inches.

For lighting to create greenwater, it actually needs not very high intensity. I believe, from your photos, that you only need to 60W to 100W T4 or T5 lighting. With non-planted tanks, green water is natuarally resulted even with low light intensity.

And please be reminded that you should always air the tanks with green water for goldfishes. The green water consume more oxygen than the fishes that may kill the fishes. That is also why a shadow tank is the key for successful. nevertheless, the more beauy the godlfishes, the worse they can swim.

Thanks for your link. It is very good.

Hi Alder,

u seems like another "BIG C" to me...

those fishes are mine, but actually they are bred by my friend in HK and their original blood-line is from Japan (Mr. Kashino 柏野正彦). They are 9 months old about 11cm-13cm long.

According to the info from most of the breeders in Japan, the height of water level is about 20cm-30cm (depends on the age of the Ranchu), of course, it is also because of Japanese Ranchu is appreciated in TOP VIEW angle..

there's an air pump in my tank to prevent sack of O2 especially during night time

I don't know if there's a difference between butterfly Tails / ranchu in terms of judgement, most of the champion ranchu fishes in Japan are with good swimming.

anyway, thanks for sharing experiences.

BUT I still have to sort out the problem of DIY T5HO for my tank, any help again

Butterfly tail looks very like ordinary black chinese goldfish. All Black generally. some may be black with golden Bottom. Most interestng things is that its tail look completely like a big butterfly when viewing from top. This fishes even have a hgiher requirement in water quality.

I never see a pure one in Hong Kong for more than 10 years already. It breefer is a very old man in China. This old man probably have some secret on this kind of fishes. I guess he may bealready dead. This kind of goldfishes may not exist any more.

hi alder,

finally, i got my lamp amended

see the pics listed below

changed to 3x T5HO 39W = 117W in total
(originally is T8 2x 30W = 60W in total, almost double the total output power)
