I've been away for a couple of days, and the algae has grown a right lot. is this okay?
I'm just about to do water tests
I've just been looking at what I can stock my tank with, How many fish can I get per litre?
Also does that figue include inverbrate or not?
And which would be better to get first? fish or inveribrate?

I have just bought wall fans to put over the tank, you might like to think of this as a less expensive idea 

When you take a sample and place it on the slide, make sure the upper cover glass is pressed with even pressure, and that no air gets under it before you take a reading. Also allow 30 seconds or so for the water sample to adjust to the refractometers temperature, allowing it to give an accurate reading. Finally, try to use the refractometer at teh same temperature each time. That should all give you more stable and reliable readings
