why no bubble in riccia? help me

[clanbuster]

i using 5.5ft length 1ft width and 2ft height.

i using 4X PL light 40W with 10000k
my CO2 is is abt 2 to 3 bubbles per sec ( i kasu)
duration : 5Am to 8AM ( 2 hrs) for me to see when i wake up)
5pm to 2 AM ( 9hrs) total will be 12 hrs already

what else have to take notes so that i can see the bubbles???
i got once able to see a few, that only that only 1 day only...

i don't think your 2 hours morning light is sufficient time for the plants (it takes a while for the Co2 to reach a sufficient level)...the evening/night period should be ok, but don't you think 2-3 bubbles a second is better? Do you only have riccia?

The general recommendation is between 20-30 mg/l CO2 for good plant growth. People calculate this figure by measuring the KH and pH of the water Do look and search through the articles and Aquatic FAQ section here for plenty of information on this.

[clanbuster]

sorry, is 2 to 3 bubbles per sec.. i type wrong.. edit now
PH 7.1 ( i using digital )
KH i not sure how to test

[budak]

use the pH/KH chart to gauge your Co2 levels.... you can get simple test kits for KH in most LFS (*get KH not GH).... we usually use sodium bicarbonate (baking soda) to achieve target KH levels (between 3 and 6 is fine).... check Aquatic FAQ for baking soda dosage... how this helps. but if you can provide more info about your tank, other folks here can give their input better too.

Clanbuster, if you dun know how to test KH, I believe you did not add anything to raise the KH. Our tap KH is about 1 to 3. Therefore, your pH should be around 6.5 or less to indicate sufficient CO2. (Remember to calibrate your pH pen.)

Your light level is on the low side for riccia. You might want to add 1 or 2 more 40W lamps.

Remember to add fertilisers too. Otherwise, algae will come knocking at your door very soon.

now i am at my friend's house. he using 5 ft length 1 1/2 height and 1 1/2 width. he using 2 x 36W lighting. co2= 1 bubbles per sec is enough. duration = 6 hrs. now is abt 6:39 Pm, i able to see 90% full bubbles.
He don't know anything abt PH or KH. at least i know PH .. hahaaaa, he simply change water every 3 mths. he just told me didn't add anything.
What the different inside is, he left 3 fish inside only.. haha.. he too lazy to take care already...

Should i buy submissable light? so that i can put the light inside the water and the light will be beside the riccia 2 to 3 cm away...

OR i found that i got snail inside my tank. the snail like riccia?? every day saw them at least 3 to 4 snails at riccia....

my PH pen is calibrated. i also kasu by using ph liquid to test. i just not happy with my friend because he do nothing, he bought his light at less then 100 and mine is 270. yet he can have it. PLUS my friend dont know the plant can grow bubbles and he simply don't bother his tank.

hi.i had use a template to lift up my 2 pcs of my riccica 10x10cm to about 1/2ft away from lighting. i believe that is super enough lighting right? i unable to see bubbles, maybe need to wait another 24 hrs...

now i set m lighting hours to 24hrs. co2 to more then 6 bubbles per sec ( too fast, lost count, i set to almost uncontrol speed) i hope i can see the result the next day when i wake up. sound like unable to wait already. wish me good luck..

by the way, how long do i need to know the result of bubbles . ( start on my lighting, take how long can see the bubbles from riccia)

[prec]

hi clan. i used to keep both mini and normal riccia in my tanks. the effect of bubbling is quite dependant on ur co2 and also the nutrients available. lastly lights also do play a role in bubbling effect. make sure that your tank's nutrients are of the suitable level and also co2 ppm is high. lighting wise should be 3wpg or more.

as for ur friend's tank, i really have to take a look to believe man. got pics?

[clanbuster]

i didn't bring camera just now. now i already back home. i can take a shot my tank. but how to insert picture here?[/img]

[clanbuster]

hi all, at last i found my first bubbles in riccia.. HAHAHAHa
i found 3 drop of bubbles in my riccia.. good news...

here is some of my photos

my fish tank. I finish setup few days ago


my first bubble. very blur, maybe i able to see

[prec]

all the best in your bubbling riccia. after some time, you'll probably give up on this irritating but yet eye-catching plant.

i using the KH kit to test. my KH = 7 dkh or 125.3ppm kh
i didn't add any KH plus and is already high???
the water had change 60% yesterday.
light running hours: 5pm to 7am ( 14 hours)
now my light 6 x40W + 2x 35W

[clanbuster]

upz..
anyone can help?

[KoiSG]

I got the same problem a few weeks ago. Good Light, Good CO2 but riccia isn't bubbling. But I dosed with K and iron, riccia starts bubbling the next day, maybe thats your problem?

[goh]

Your have 310W light which is definitely sufficient (in fact 240W) should be enough.
You need only 10 hrs photoperiod.
If your KH=7/PH=7.1, then CO2 level should be abt 20ppm which is good.
You did not mention your nutrient dosing regime. What about the other plants in the tank, how are they doing? What is temperature of tank? After a massive water change, you probably need to wait a day before you can see bubbles as the water needs to be saturated with O2 first, and that is provided you have dosed all the required nutrients for the plants.

[budak]

I think folks like Tom Barr have noted that riccia is the best indicator for Co2 levels. Assuming lights/fert etc are in order, no bubbling = CO2 is insufficient or unsustained. Try to go for at least 25-30 mg/l throughout your photoperiod.

[clanbuster]

haha. at last i found why don't have bubbles. I think 8 x PLC light also useless because remember i said 2ft height?
Recently i tied up my driftwood with riccia to (almost top surface) the bubbles came out abt 1 hrs or less.

Maybe i think of buying spot light abt 600W per lighting. Does anyone know where selling. Because i asked one of the farm shop, there using that, but there also forget where there bought it.

10000k, isn't that meant for Marine tank?

planted should be 6500k daylight???

[wks]

Hi clanbuster, I noticed your lighting period is too long. Algae will come soon.

[clanbuster]

10000k should be marine tank lo.
stupid c328 said for plant. he just want to sell it away.
no choice have to wait until the PLC blow off. how long is the life spent?
