I've got the same biorb, also in the corner of the kitchen, I've a few cloud minnows and one Harlequin razbora in it. I don't put the light on for too long, couple hours in the evening. Also you need to watch, the hole at the top forfeeding can get clogged up, I feed mine Hikari food, but hole does get blocked, I check it every two weeks and clean it. Your fish are beautiful.
There is a very different set up in there now. A few more plants and different fish. I'm having great success with that tank, probably the lowest rate of deaths from all my tanks.
@@PeterL82 we had a 195 litre corner unit, and a python for the water changes, we had that as well as the biorb for few years, arthritis in knees getting worse, so we decided to move to bungalow somewhere, so had friends who took all the tropical fish and gave them the corner unit and fluval 306,i needed to know my fish were going to be safe, so just due to move this Friday 15th May, but lockdown put paid to that ,so had a few natural deaths in remaining biorb, and as we planned on moving, didn't want to replace with more fish, so just have 5 now. Can't wait for a Wee shoal of tetras.
Im not sure if you can, but on the standard day/night setting, it will eventually get brighter throughout the course of the day and then dull down as it comes to the night setting.
