Guess it depends on the set up

What exactly do you mean by 'go bad'?

1) it's always good to have a skimmer, it's not always needed but its a good thing to have on a nano that cant have enough rock fitted in to lighten the bio load a bit more

2) even if its fuji you still need ~1kg of rock per gallon no matter how porous it is

3)the only way to have too much is if your cramming it into the tank, thats blatently toooo much, but if you have sense then you wouldn't do that would you?

4) my info isn't misleading at all, it's how i've set-up all my tanks and it's whats always worked for me

and finally
5) in what way would my advice make a tank go bad? none of my tanks have gone bad following this advice

All the information i've got off all the people at fish keeping has been really help full, it isn't misleading at all. Thanks everyone for taking up some of your free time to help all us beginers out.

What works for 1 dosent always work for others. Im still sticking by my 1 pound per gallon on the LR. This is the only forum where they say its 1KG per gallon. Im not saying anyone is wrong

no it's not, i've been on multiple forums and they've told me this as well

well, i have read in many books and many websites, 'approx 2lb per gallon' is the ideal amount, which 2lb = 1kg roughly. which is why i set up my own nano reef tank with 2lb per gallon. we dont just make up our own rules on this forum you know!

Calm down

at the end of the day live rock is expensive and it is best to get as much as you can afford..and as close to the 1kg rule as possible for the best outcome/filtration.

Was in a local Fish shop on saturday and he said that 1kg per gallon in a nano was a load of c**p and that i only really needed a peice the size of a coke can in my 8gallon and to put all the media into my external fluval 304. :S He then went and said "look at all our displays tanks and how much we have in them, you could put around 10 fish in there aslong as u have the filtration" ....
