Different situation, but same results;

My coral reef aquarium bites my ass.
I'm getting new and more delicate coral, so i'm upgrading my $120 lights with $200 lights.
My water needs to be skimmed, so $115 protein skimmer.
I need to reduce my phosphates so $60 phosban reactor
I need a more pure means to water so $200 reverse osmosis/deionization water filter.

It fucking never ends.
