Frag, Have you noticed any difference in your tank since you started to use this?

Mark Melev is starting this as well:

I'm almost at week two which means that I will be dosing another dose of biodigest very soon. So far I have noticed enhanced protein skimming, lower nitrates, and some of my macro is begining to be affected. Though it is still too soon to make any difinitive conclusions. I'm not sure that I will continue using prodibio after my supply runs out as I kind of enjoy having macro algae in my refugium.

Any Difference in your corals yet?

Some corals have improved in color over the past 5 weeks and almost all have increased in growth. It is difficult to tell how much is a direct result of the prodibio though. My macro has definitely shown signs of declining. Since starting the prodibio I have also started siphoning a few cups of sand off of the top layer of my sandbed. Over the next few months I plan to slowly take it down to about an inch and then build it back up with fresh sand. After five years there has been a lot of buildup. When I started the prodibio I started doing 5 gallon water changes 4-5 times a week, so almost every day. I have changed my routine and started changing 30 gallons per week instead which I think is much better in terms of water parameter stability.

So to sum it up and answer your question, Yes I think the prodibio is working but it is difficult to get a direct measurment of the results. Prodibio is not a fix all solution to my nutrient problems but I think it is one prong in a multi pronged attack to reduce my nutrient levels. :)

So what's your conclusion on the use of prodibio? Your supply run out?
