Latest on dosing Vitamin C....

[CalmSeasQuest]

All of my parameters are in check with the exception of my Phos which is at 0.31PPM I am working on this by use of a Bio Pellet system that has been up for 1 week.

Did your Zoa melting issue coincide with the start of bio-pellets? Do you have elevated Nitrites, or just Phosphates?

Did you start initially with a small amount of pellets?

Calm- My Nitrites are in the 6 ppB (Billion) range and my Phos is at .31 ppm My Nitrates are at around .25-.30 ppm High for sure.

I have had this issue b-4 the use of the bio-pellets. The last time was about 6-10 months ago when I lost a whole colony of X-Men paly's. In total this has happened to me about 4 times now Bio-Pellets: I have taken the total amount needed (4 cups)-devided that by 4 and have been adding each dose (1 cup each) at one week intervals. My PH has been in the range of 8.19 to 8.45 and I have not ever noticed a sharp spike either way.

One interesting thing is that it has happened to me in both my Display tank and 30 gal Frag tank (not at all connected to the Display tank), so whatever it is that is that I am doing wrong, I am doing it to both tanks???

Anyother thoughts? Thanks!

Any Salinity fluctuations? Salt changes? Alkalinity fluctuations? Alk level issues within the listed time frame? How about lights? Type and age of bulb? Flow rate and flow type in tanks? Also if you are doing MB7, many people have noticed a issue with keeping many types of zoas when carbon dosing. Could be you started with one issue, and the MB7 is simply building on that.

Renegade-

Sorry for the late reply's here guys. Work has been CRAZY so I do not have much as time as I would like to have.

All check out fine. My lights are a good point as I do have HQI bulbs that are around 14 months old. However I usually run them for 18 months as I average only 5 hours a day in my photo cycle. I run Ushio bulbs so they are of good quallity.....Hummm now you have me thinking about it :-)

Flow is via 1 Tunze (6065?) and Iwaki return with an output of 1500 GPH.

I do not dose MB7 but do dose a Special Blend Bacteria. I am thinking that the combo of S. Blend and the addition of the new Bio-Pellet system might be bacteria overload? I am going to stop the dosing of S. Blend.

Your thoughts?

Thanks for all of the input!

if it was my tank i would be pointing at the light bulb as halides go through a heavy light shift as they age.

Good point Salt....it is just that I have run this brand of bulb for 8+ years now and never had a problem with going 18 months. I guess I am leaning towards replacing them now to.

Do you run HQI's? If so what length of time are they on for and for how long (months) do you typically run yours for?

Thanks for the input.

I am no expert but I ran the same bulbs and never got past the year point with out problems.
I would change your bulbs and stop using the Special Blend Bacteria. The Bio Pellets done the way they are supposed to should be enough.
Any time you need to make big changes do it as large water changes and don't double up on things.
