Possibly a stupid question

Hi, I was wondering when calculating lighting, filtration, ect, do you work it out on the volume of the empty tank or do you work it out by measuring the actual amount of water when hardscape, ect is added?

Thanks

As a general rule, use the volume of the empty tank. Of course this isn't always best as tanks differ in size and shape.

Hello. You will find that most use over filtration . Meaning a larger turn over of ltrs per hour that recomended when using external filters. I have 220 ltr cube and my filter is suitable for twice that.I was also using a fluval 2 in the tank to increase flow. You can always slow flow down by adding extra media/fine foams to the filter if its a bit fast. So I would calculate on an empty tank then buy the next size up. If I'm adding fertilizer to my 220 I probably under dose as I dose for 180ltrs of water as I have a lot of gravel and wood.. I am not the person to comment on light calculation. What set up/tank do you have. A bit of info and someones bound to help you there a good bunch on here

Slow journal is better than no journal mate, the journal forum gets more views than any other forum so if its advice your after stick it up there
