First let me say I'm sorry to hear about your losses.
Now would be a good time to take a breath and analyze your prior experiences with this tank. Some large PWC
's are in order. Take the time to solve your algae problems before buying more livestock. Stop dosing anything and learn to keep the levels normal with just water changes.
First get the tank under control. That may mean cutting off the lights to eliminate the algae. Consider adding more live rock, a sump with macro algae, removing the other filters, etc.
Take some time to re-cycle your tank and take a fresh start. Get a RODI
and use only RODI
water for all water changes and top off. Think about the foods you use and what they add (PO4
) and learn to eliminate the bad.
Just slow it down, take your time and you can have a successful tank.
