I just had to purchase Red Sea Reef Energy AB+ ( 4 litre jug) again as i had run out and cannot believe how expensive it is now. I paid $165.00 cdn for it and the last time it was $145.00 CDN. I see now that some stores are charging $189.95 CDN. While i understand that everything has gone up, when do we say that's too much and either find an alternative cheaper option or start to rethink the money spend on our hobby. The reason i bring this up is not because I am complaining but rather would like to hear others opinions on this and also see what other alternatives there are for feeding your corals.
