Hey charl. In the 2nd pic they were, but they currently blowing just under the water level towards the front glass. One blows accross the other. No direct flow.
Unfortunately the subtrate must stay for now. Im doing 2 small water changes and syphoning everytime.
Removed the sponge. Have filter floss which I replace with every water change.
The first pic is what the scaping looks like now. Pic 2 was in the very early stages. It was just to show the light unit.
Oh, i see. Sorry, my bad then. looking at the second pic, looks like you have a lot less algae. Good husbandry will turn your tank into a gem, and looks like you are doing a good job.
