Definitely, 4hour is what I am on now too. Quality time vs quantity time.
I have noticed some BBA on some of my Monte Carlo and was considering to keep lights to only 4-5 hrs per day. With this I hope to reduce more BBA growing as well as slow down the growth of my plants. Will they survive if I change my photoperiod? Currently is 4-2-4

How is your current flow? Generally, BBA grows when there is a great fluctuation of CO2 or lack of good circulation.
I think the circulation should be quite good as I'm using a 2213 as well as a HOF for a 40L. Hmm as for co2 fluctuation, not really sure what it means as it's on 15mins before lights on and I off it 30mins before lights off. Currently running 1bps per minute with inline diffuser. Plants seem to be pearling fine.Originally Posted by hann
At least it's trial and tested
Increase your water change frequencies and try dosing some Excel, this helps to rid bba
I had used algexit as a prevention, following their recommended dosage of 5ml per 100l every 2 weeks, but the BBA still appeared.... Must be terrorist BBA
Your AlgExit dosage might be too low to have any active effect on BBA.. maybe try the recommended 4 week treatment course of 1ml per 10L per week for your tank volume, see if it works better.
Its not a cure-all solution though, low circulation in certain areas of the tank (and thus not enough Co2 reaching those areas) are still more susceptible to recurring BBA issues. Have to combine with manual removal and excel/h2o2 spot treatment to keep it suppressed.
first of all less light time will not get rid of your BBA. Increase your CO2 to 1 bubble per second instead of per minutes. 4hrs per day maybe ok for some plants but some plant like rotala, you will see it start to lose their bottom leaf.
The BBA was just abit here and there, I cut off the Monte Carlo parts they were growing on, was just surprised that even my prevention measures with AlgExit, they still appeared. Yup co2 is at 1bps, and plants seems to be pearling fine so I thought it might be due to too much light.
I have gone ahead today and allow the plants only 4 hrs of photoperiod per day. Hopefully my Monte Carlo would do fine with the changes. Will trial for a week and report back haha
I noticed that if plants are 'spoilt (brat)', they also will not survive for long. I once bought a variety of Java fern from a fish shop and it died after becoming brown all over within two weeks. The reason is probably because my tank is exposed to little natural light ( I have no lighting for the tank), wherease in the shop, it was exposed to good tank lighting. But my existing Java fern in the same tank are thriving and growing profusely, having many tiny offspring.
LIFE IS UNBEARABLE WITHOUT A FISH TANK!!!
The fern at lfs is grown emerse, the emerge leaf will die off.
Secondly, its normal for plant to shed its leaf when light intensity drop. It is about the amount of energy generated during photosynthesis vs. the amount of energy used to support the plant mass after photosynthesis.
If the plant was grown it bright light move to dim light, the energy produce not sufficient and it start shedding leaf. Same goes when you reduce light hour.
How much is your CO2 injection?
You're running 1 bubble per second (bps) per minute with inline diffuser?
I see a vast difference when my light session is reduced from 7 to 4 hours. My experience was when I was trying to conserve the co2 till the weekend to get it refilled. I reduced both co2 and light to 4 hours and the outcome was that the plants looked frail. I observed that my rotala was conspicuously weaker from the result
I believe it stablishes at 1bps, that's after the initial surge to make the diffuser work.
Yeah i Shadow did mention about that happening to his Rotala as well. Lucky I don't have any in the tank. So far for 3 days, I don't see any degenerate from my MC. Hopefully they stay this way and can get by with just 4 hrs of photoperiod.
