alrite!!! the eureka reds spawned today...this is her second one...first ones didn't make it...i will get her our into her own tank this time after a couple of weeks...
When I did my rescape, I put all my rocks on eggcrate with legs. ie all the rocks are raised off the bottom so there is a load of flow going beneath them. Basically, everything falls through the rocks to the sand, then the UGJ blows them into my filter. It's great, I love UGJ systems, they are worth doing for sure.
Your tank looks amazing, apart from the turtles. The jets looks superb, I only went for less in my tank as I wanted them to be more powerful.
