Hi I am reasonably new to tropical fish and *have started getting problems with alge growth in my tank. Can anyone give me pointers in how to stop the alge spreading.
It's different Alge to what I normally see, it's like a mini plant (almost grass) but only grows about 10mm high and then spreads! It's not normal green alge, it more black!
I no phosphates are a contribution to alge, so what is the best thing to get to test this. Also how long do u recommend the fish light should be on in one day to give my fish and live plants the best lighting.
