I have a 120 gallon tank that has been setup for about a year now. I have lost 5 fish recently due to water quality and not changing the water as much as I should (Assuming). I have added RO water when salinity was high to maintain it. Changed the water once a month or at least tried to. I want to set this aquarium up right and give it one more try (Before the wife tells me to get rid of it). I've provide pictures of what I have.
Filter: I have a Fluval RX6 canister filter with 4 air lines to the tank.
Flow: Hygger HG042 on opposite end of the filter flow and I have another small fan next to the filter flow to assist.
Lights: two Fluval Aquasky 1200mm lights
I have a phosphate reactor from BRS but have not set it up yet. I noticed my phosphates have grown to almost 1.0 ppm. Thought this would assist with this issue.
I have not gotten a protein skimmer as $$$ is an issue and I do not have a sump setup.
I need some advice on what kind of flow control would you suggest?
Do I need the protein skimmer?
How would you suggest installing the reactor on this setup? I am having a hard time installing things as it seems it requires some custom clips to hold the hoses.
Any suggestions on what I should do (other then more water changes, I know I know) that I'm not doing?
List of fish that died - Yellow tank, blue tank, lemon peel angel, yellow tail chromie, and two snowflake clowns
