Thank you! I am running two 4' atinics and two 4' 20,000 K full spectrums bulbs.. and I use $8 home depot light fixtures.. Last week I just replaced all the bulbs. The sharks will outgrow my system in about 2 years...... When that happens I have an aquarium maintance buddy that will take them for me... (we use to be partners, but there is no money for 2 people!!! so I kept my day job! LOL) plus I have 2 other places that will take them..
These sharks are the reason why I got back into this hobby 4-5 years ago..
