Effect of direct sunlight on my planted tank?

[yck]

Is it Recommanded to place tank beside the windows where direct sunlight shine upon those plants ? will i lure green alage invasion ? cos i find direct sunlight more "power" than FL tube . just to share i am using acradia tube but they arent as good as direct sunlight.

my 1ft shrimp tank and only have spiky moss in it and i use natural sunlight for it, so pretty low maintenance. only thing is every few weeks have to use a card to scrap off the thick algae on the tank surface.i can say its much better than normal lightings, but need to control the parameters well if not sure have algae.
will you still be using FL tube if you use direct sunlight? because sometimes the sun not so strong, like during december, almost everyday is abit gloomy so my moss some part also turn brown.

erm i think thats very difficult to achieve, if not impossible. for my 1ft now, i can see green algae growing already and getting thicker slowly, and that is really a heck care tank, only do top-ups and still get algae. thankfully, my moss are healthy maybe its due to the countless number of cherry shrimps inside my tank. by the way, i only feed them occasionally, like when i want to hold a meeting with them

agree with bro hebi, it will be very hard to prevent the growth of algae esp. when you use direct sunlight.

My pico tank with HC and hairgrass is on direct sunlight. It only gets direct sunlight for a few hours in the morning. I supplement it with excel and a pinch or two of KNO3 and PO4.

Other than slight algae on the tank walls, no other algae is found. Plants are growing but slowly. Its been only a few weeks old and hairgrass is sending out runners and the HC is sprouting new leaves.

I had a 2ft planted tank in the balcony with direct sunlight. Serious algae bloom on the glass and everywhere (includung growing on mosses). SAEs, OTO, Snails, and all other methods including chemical treatment don't help much. And what's more, certain plants cannot take too much strong rays. Personally, i feel that there're more cons in placing a tank at direct sunlight than advantages. However, if the direct sunlight is diffused thru a window glass, that's a different story..

its always advisable to keep tanks away from sunlight, not just keeping algae down but also keeping water temperature stable.

UV would help you get rid of green water.

IMHO more/stronger light plants will grow faster, thus require more fertelizer and CO2. Otherwise algae will taking over. I never try it though so can't tell you more, only opinion.

Bro YCK,
General fish-keeping guidelines usually advises against
locating your fish tanks in areas where there is direct
sunlight. This will leads to algae bloom and related
problems. Of course, if you ask around, there would be
some exceptions but this is one of the cardinal rules for
fishtank placement.
