First post on here so I hope it's in the correct place.
I am in the lucky position to be planning a new tank set up. It will be a 400lt, 5'x2'x2'
For the last 20 or so years I have been playing with planted tanks, currently running a 360lt with 2 Eheim canisters 3 x tube lights and co2
Things have moved on a bit, so my first question is the filtration rate, I read on here that 10x the tank volume is the norm. I'm currently at an otpomistic 1800 lph. Can anyone suggest a new pump? My Eheim 2126 is 16 years old, and the 2324 is close to that.
Secondly the lighting, led or keep with the t5 and t8 ,s
