Hi Syed
IMO 86watt light is bit less for your tank size. Seniors can throw some light on appropriate wattage needed.
And min 8 hours of lighting is suggested.

IMO melting has got nothing to do with lighting.
What seniors say , melting is a signal of lack of Macros....I have little knowledge of nutrients.

Can we split up the photo period like that? |

@ hems,
I wont suggest for the split lighting. As when you start the lighting period, the photosynthesis might not occur immediately. It will take time for the photosynthesis to occur. And you switch off the light in 3hrs. So the photosynthesis is not occurring continuously.
In addition, the lighting is only 2 WPG.
Which plants are melting off?
How old is the setup? More than one month, then it is supposed to be 8hrs per day. |

@hems
The photoperiod should be 8hrs a day and if you provide it at a stretch then would be better as mentioned by Shelly.
Are you using any reflectors for your lights?? if you are not using any then a lot of it is going waste. A good reflector with the lights is also very important. That CFL wont provide you any penetration as your tank is 18" tall.
A major reason for melting of plants is lack of nutrients, but as you dont have a CO2 setup (a pressurized one) it will be a problem if you increase the dosage of nutrients as it may invite algae. In case you decide to increase the dosage better ensure consistent supply of CO2. |

Hi Hemesh,
After 3-4 months, do you still feel that the split timings are working good for you? (2 hours in the morning and remaining hours in the evening)
You have mentioned the results of 1 day.
But over a period of few months, what is the result?
Regards
Sujo |

Its not that you will not have alage 100%. But if the other parameters are not taken care too, it can cause alage.
Even I am yet to try this split period of timing as my tank has a serious Staghorn alage. So I am going for a split timing and going to check if this will control the algae. |
