Scott's 270g aka Project Mayhem

So how then with my system which was brand new, and tested flat for nuisance nutrients started getting a cyano problem? Then I take them offline, the problem goes away AND my nutrients stayed at zero's. I did buy them and the reactor with the idea to run them at all times, but then got cyano which the pellets are supposed to prevent are they not?

My last tank had hair algae and bryopsis, so in planning this one I wanted to use everything I could to prevent that nutrient build up! I'm not saying I won't try to bring them online again, just for now I don't have any issues so I don't want to introduce them.

Well,... there is a simple sure preventative for cyano. It's called MB7, and a must use with bio pellets, IMO. I have discussed it here many time....

Scott, I think what happened with your biopellet experience is that you were using too many for the amount of available nutrients. That's what I find causes cyano with biopellet use. Discussions with some very experienced professionals seem to come to the same conclusion. The amount of biopellets used needs to match the amount of nutrients available for the biopellets to feed on. Since your tank is so new and you have such massive nutrient reduction equipment already in place, it is possible that 1/2 cup of biopellets would be too much. In my 90-gallon SPS tank I used fractionally less biopellets than was recommended - any more and I would get cyano growth.

I've tried MB7 additions for cyano, and I've never seen any reduction in cyano. I know lots of people report success, but it's far from a "sure preventative".

Exactly how did you use MB7, dose amounts and time, etc? Did you try it to reduce or eliminate cyano that you had in your tank, or use it as a preventative starting with a clean no cyano tank?

I stand by it as a sure preventative,... if used correctly. Like I said, I have discussed exactly how to accomplish that several times here in the past.

Honestly right now my problems aren't the algae type so I am not even thinking about biopellets lol. I am still trying to get my Ca, Alk, Mg balanced.

^ Pretty much.

It's been somewhat of a pain in the butt! I had my numbers balanced and started dosing equal parts of the three part ™ system. Within 2 days my alk and mg was low and my ca was ok. I up'd my Part B & C dosing and it seemed like no matter how high I kept dialling up my dosing my alk & mg wouldn't go up. I was dosing extra Part C to try and raise the mg but I could NOT get it past 1300 according to my salifert test (confirmed by Bayside Corals test).

Maybe the chemistry experts can help me. I have ~300g of water volume. I made up the ™ recommended mix of a one gallon solution and have been dosing 2 x 175ml of part B. Two days ago I had an Alk of 7.4 and today I have an Alk of 9.4. What's going on!?

I lowered my dosing back to 2 x 150ml a day Part B and will see what happens in a couple days.
