First of all, thanks for letting me have a chance to be in such a nice forum. I am new here and to planted tanks, so I actually need your ideas about what to do.
Well, I have been in the hobby for over 10 years dealing with Malawis, which tells why I didnt use to be interested in planted tanks. I never give up on Malawis. However I decided to set up a new planted tank using my backup tank in my office and I have been reading what I found about planted tanks for weeks. It seems quite nice but difficult at the same time. So your suggestions are very important to me.
My planted tank will be about 160 L (about 40 US g). I'll be giving yeast CO2 and having about 60 W grolux bulbs. I think this should have been higher, at least 80 W or something like that but it seems nearly impossible to put more bulbs within the top cover because of a lack of space. I haven't decided what kind of plants I will have but I will try to find not that hard ones.
Many people around tell me to find a high quality substrat but the term "quality" extreamly depends on many different approachs. Therefore, I am thinking to use a suitable sand, peat and aquaclay.
As for the location of the tanks, the problem hits me especially here. Because I can provide only 60 W for the 40 g tank, I am thinking to put it close to the window so that daylight could be useful for the plants, but what about the algaes? The tank will not get direct sunlight but I am not sure if it is a good idea to keep it very close to the window. Shouldn't I do this, I don't have enough light though?
