thanks Alastair, that is useful information!

thank you all for the feedback! @Arne I like the idea of placing the spraybar on one of the sides instead of the full size background - what about the complete flow from one side to another? I'm scared that my nutrient/CO2 distribution fails because of a wrong flow. Do you have some pictures...

I'm using a Tetratec EX600 which is being delivered with several filter media like wool, sponges, ceramic pipes and bio-balls. I want to "generate" maximum throughput with my filter and therefore remove all unnecessary media. Can someone advise what can be removed and/or replaced? Is it for...

Thanks for all replies, very useful links.... One question; I can increase my outflow a little more, but the plants at the other side of the spray-bar are moving quite fast than (maybe to fast??)... Is it assumable that the plants that have more flow around them will grow better (healthier?)...

sounds obvious, but would one or two holes really "damage" the whole circular flow you think? At this moment I don't see any issues yet (tank is running almost one week), but I only observe that there is much less flow the first 6'' from the spray-bar. I'll follow up your advise to not add...

thanks for your replies! @ceg - what's the risk you see in doing this? My theory is that the outflow is spread more effective, especially on the first part in front of the spray-bar and directly underneath it.... At this moment I've turned the tap of the outflow of my filter a litter closer to...

I'm using the spray-bar vertically placed in my 60x30x35cm tank and the filter I'm using is a TetraTec EX600 (600l/h)...... (is it better to convert my measurement units to UK units??)... There is a good flow to the other side of the tank where the flow from the spray-bar clashes to the...
