hey there,
this is my first post on this thread. Thanks for all the hard work and devotion.
I started dosing Vit C about 1 and a half weeks ago. I am using ascorbic acid from the Vitamin Shoppe, 1/4 tsp. is 1000 mg. I started dosing 1/4 tsp twice daily in a 90 gallon, then bumped it up to half a tsp. and now have been doing one tsp. twice daily. The 90 gallon is a mixed reef, mostly sps, some lps , stragler shrooms and a few zoanthids and palys that have survived the magical disappearing act .
I pulled all the zoanthids I could out of the tank and set up a 15 gallon. Along with a 12 gallon cube that holds RBTA and clowns I tried to save the zoanthids. Fresh water and iodine dips, inspection of each frag for pests, and cleaning of unwanted debri still left me puzzled. I probobly had around 20 small frags in the 12 gallon pod and another 20+ in the 15 gallon. They are all in the 15 gallon now.The zoanthids were holding but growth was not great and then the frags would receed and come back smaller.
So, my results have been.
On the 90 gallon, first thing I noticed was the smell of the skimmate changed. I am pulling twice the skimmate I was before dosing C. The foam has been "thicker" and the bubbles smaller and more condensed. The other noticeable difference is the filter sock. I used to change the filter sock every three days or sometimes longer if feeling lazy. The sock would be dark and filled with goodies. Now from dosing C the sock gets clogged after two days, and fills with water which lowers the level in the sump . I can either change the sock or add even more make-up water. Plus there is not as much gunk trapped in the sock, the sock almost looks clean.
Now on the 15 gallon I stared dosing twice daily. Using 3 small scoops with the salifert test kit spoon. I calcualted 5 salifert spoons is approx. 1/4 tsp. On this tank I am running a power head and a penguin hang on filter no skimmer. I would clean the filter weekly by banging it the sink and rinsing with water. Most of the carbon has been beaten out. A couple of days ago the tank was very cloudy, so I stopped dosing and did a water change. Today the water was low and the filter was producing many bubbles on the water surface. This happened because the filter was clogged and the water was rushing around the pad. When I cleaned the filter it was the same deal as the filter sock. No noticable solids, maybe a film of some sort clogging the fibers.
I am going to keep dosing on the 90 and looking for a used skimmer for the 15. I believe that the skimmer has much to do with the dosing of the C. I am going to go with a smaller dose in the 15 and see what happens
Have some RPE in the 15 gallon that were closed up and have what looks like zoa pox, today they were opening. Some of the other zoanthids in the 15 are doing much better allready, the difference before and after is noticeable.
The 90 gallon has a noticeable change too. Some of the zoanthids that i thought were doomed are more open and brighter. It has been a short time but I have high hopes that this could be the answer.
I am going to build a phosphate reactor and run some phosban, has anyone had problems running phoshate remover while dosing C.
thanks again
