(please ignore the aquarium quality , will buy a new one if can grow plant on it)

Please suggest if the light is too high for this aquarium size.

Also, please anyone can confirm whether galiff market is open on coming Sunday (8thOct)?

[Sushil]

I would suggest to reduce lighting to 8 hours and consider supplying co2 in one or other form.

[Atanu]

Thanks for the reply, I will consider excel. Also, is it good to reduce to 9w or 11w led bulb? Anyone can suggest if any spot light available in general electric shop which can be used in 1 feet nano?

Keep everything as it is...start changing 50 % water change in every alternate day...algae issue will not b there..

Thanks Nirmalya for your suggestion. WC 4 times in a week is difficult for me. I will try it twice in a week.
Also, I have 5 adult cherry, 8 baby cherry and 2 assassin snails are there, I feed them tetrabits. I dont want to add fish because of shrimp.

Changed the scape.
removed - red amazon, java moss
Added - Christmas moss, reineckii mini, HM moved to left-top corner as a background plant.
Started excel dosing everyday.
Photo period - down to 9 hours

lets see how it goes in next 10 days.

Donot add excel. Your Sag and hair grass will melt away. Excel is nothing but glutaraldehyde.

Lower your fertlizer dosing and lower the photo period.

I maintain the same size nao aquarium with heavy plantation and 4 serpae tetras and 4 guppies. I have CO2 DIY and 18W 8000 K PLL and 36 W 6500 CFL. My photo period is 8 hours
Little algae

Thanks for you suggestion subhendu.
I am adding 0.5ml excel and can not see any problem on hair grass.
also, my fert dosages is already low - 4.75 ppm K, 7.15 ppm NO3, .5 ppm P after water change twice weekly.. thinking to increase K as I can see some deficiency on plant leaves. need to add extra Fe as well for red plant.
Photo period - 9 hrs
substrate - this is the main problem. amazonia is 2 years old and can not provide any food for plant, should i leave it or add some potting soil ? dont want to buy amazonia. I used normal garden soil before in other aquarium and worked very well!
Current problem - little hair algae in hair grass which i am removing every 3-4 days. green layer on aquarium glass which I am removing manually twice weekly before water change. also,not happy with plant growth.

[SanamMarik]

for algae control- up the PO4 levels to the limit where plants dont stunt. and lower the K levels to the point plants dont show deficiency. what is ur N level? try to add some co2 source for faster growth

[Atanu]

earlier dosage was NO3 - 7.15 ppm, P - .5 ppm and K - 4.73. also, .5ml excel everyday. then 2 weeks back i removed all plant and added dart layer in substrate and replant them. also, increased K to 15 ppm and suddenly can see the rise of algae (fungus type all over the plant leave). thinking for a H2O2 bath. would it help? anything else i can do to get rid off this.
btw, plant growths are good now but algae taking the control fast.
