Phytoplankton Problem

[Matthew5664]

As stated I have a 60L with very green water. I'm using a 50/50 PC tube above and am thinking that this is the cause? Blue wavelenght promoting the high algea growth. I'm not in a position to change the buld as yet (£) but need a soluton. Would carbon work? 75% water change??

Please help...........
Thanks
Matt

3-day blackout, entirely - no peeking or feeding the fish at all. Doesn't treat the root cause though, how long are your lights on for, do you use CO2, fertiliser and does the tank get any direct sunlight?

Carbon will not do anything, it is purely a chemical filter media and will not remove much in the way of particles.

how long are your lights on for 12Hours
do you use CO2 No
fertiliser No
does the tank get any direct sunlight No

Black out still goes, personally I would aim for 8 hours of light, 10 max though 8 should be more than enough. Longer light periods don't compensate for lower light levels.

Yea the blackout would do the trick but that's a temp fix aswell, if you keep it all the same you'll have the problems still

I wish i had green water lol, then maybe my otto's would breed
