I have a 110gal Tall tank with a sump and an overflow, i want to convert it to a high tech planted tank here it is:
i already have some of the things ill be needing
substrate (safe Tsorb)
dual t5HO light
My question is the sump
What part of the sump i need to cover? the top and the holes?
The c02 will be on 24/7 ill feed the c02 light close to the mouth of my mag12 return pump.
Basically my main concern is the sump loosing all the c02.
