Folks a (small) update.
Found a problem with my heater choice so ill have to make another mini OHF to accomidate. but no rush on this since i have till next summer before i can work on the tank.
Doing the math ill get around 2.4-2.8 turnovers per hour. Through filter socks and about 264L of matrix. Do you think this is enough. I hope so.
The OHF will be drilled for a UV light just incase the indirect sunlight will give me issues.
Right now im just doing prep work. Making lists of things to buy, things to do.
