For lighting I have decided to run with the Up Aqua U series (Planted) 3fts. I have been really pleased with their output on other systems. I currently only have two on hand but thankfully will have the others by the end of the coming week. :)
I have gone for the same sump type as last time. First section for K1, then flowing into second chamber with filter pad, Marine Pure spheres, Bakki Balls, Purigen and Polyfilter once established. I had the sump custom built for me this time.
I will be using a 300W Aquael Gold Heater and a 200W Petworx Heater.
Return pump I have gone with a Tunze again as I have been pleased with the consistent operation of current one.
I added an airstone in the K1 section for addition water movement, this way it keeps moving even when the return pump is disabled.
I let the system run at 27 degrees for two weeks and have only just added some cycled K1 and Marine pure from other sump.
I added two new marine pure spheres, the difference in colour is kinda startling.
In this last image I have just added the chiller, we are having a premature heatwave in Victoria this weekend so wanted to get it ready. The green tubing is the chiller. I run the chiller separate to main return and just chill the sump. This way return flow to the tanks is gradual cooling and it also makes it easier to add and remove from the system without affecting everything else. Seems to work well on current rack?!?
