I can not find any customer service with Landen aquariums to help me with my 16g AIO biocube. It's been up and running for about 2 weeks with live rock from my other tank and live sand . My question is it came with no instructions - I really need instructions. How much water do I put in the back chanbers? In the first left changer is the protein skimmer. Second is the heater and I just put in the 16 g Coralife biocube filter, the third changer is the water pump that came with it-(LANDEN BIOSMO 700 Return Pump) . Not very strong so I put a powerhead in the tank which I really did not want to do. Do I need a media basket also? If so with what media? This will be a nano coral tank. Any help would be greatly appreciated!
