I'm posting my experience w/ vertex biopellets in a vertex reactor with 320 gph flow threw the pellets with a quietone pump. This is my second time trying to balance my system w/ pellets and seeing diffrent results with both cyano and the amount of pellets my system could handle before things started to go south with the corals. I'm hoping this can help anyone starting out and help w/ the cyano problem everyone seems to come accross.
I started the vertex pellets in november '10 just a month after setting up my 40gal. All live stock was from a 22gal cube that i had up for a year.
22gal:

and into the 40gal

I started the process with 2weeks dosing two cap fulls of MB7 every morning w/ the skimmer off for about and 1hr somethimes 2hr and 100ml of pellets. after 2 weeks everything looked good then added 100ml. (seems like a lot of pellets but everything was looking good. PE was great corals where bright, fish where loving the extra feeding and no cyano. i was feeding about a cube of mysis a day. at this point i had added 2 other fish.
So, this is the tank in December

then in jan '11

so water looks super clear, corals are very bright, fish are really fat.
I kept my regular husbandry. 10% water change every week and adding cal and alk w/ top off.
i was very pleased w/ results except for a green algae on the bottom of the tank. i still felt like there was phos in the tank because of the algae, so regrettably i added 200ml of pellets. (y i know, bad move)
so Jan 13 add 200ml for a total of 400ml, so two weeks later this is what happened:

so, thought it was red bugs, thouhgt it was the pellets putting too much nutrients in the water (because i was told that they feed your corals and that you could not overdose) had no idea. i started water changes and everything got worse. well after taking the pellets offline and doing hrs of reading here on rc about everyone experience with biopellets i finally realized it was the pellets what stripped the nutrients and starved the corals. but never had a cyano outbreak..????
so after feeding for a month and i mean heavy feading i finaly started to see some nitrates. corals started coming back. actually everything started coming back, algae and for the first time a small amount of cyano, but nothing crazy, nothing that i was worried about. i figured i would be able to get it out with water changes and the reduction of nitrates.
