Im lazy and just drop the tablets in a low flow area and let them dissolve , i dont have any fish so i dont have to worry about them eating the chunks.

I put 1000 mg into system yesterday and skimmer went crazy. But I'll have to check ph today and see if that is y

sodium ascorbate never affect my skimmer.

Have you considered increasing or changing the flow patterns to help get rid of the bio film?
I find that pointing my tunzies up towards the surface creates a lot of gentle swirl kind of flow that corals like a lot

It's not even a question of flow, as the biofilm also build up on the pumps where the flow is highest. It's just a matter of carefull adjustment of dosing until things stabilize.

I used to use Vit C dosing for a while with great success. I now only use it if the zoas seem to be unhappy as I already use other forms of carbon dosing.

Now, because vit c is a carbon source, you have to be careful adding it to your system. You need to take a similar approach to vit c dosing as you would with any other sort of carbon dosing: start low and slowly increase. Adding too much right off the bat will cause a bacterial bloom with can crash your tank. It can also strip nutrients really quickly from the water which can often trigger STN in acros. There is an old post I think on RC that said how much to use per tank volume and gave a dosing regimen (can't exactly remember where... maybe check with ZoaElite. He might remember.).

Titus99, if your skimmer is going nuts, you added too much. Give your tank a few days to mellow out they try again but GO SLOW!

My thought exactly about overdosing. I will wait a week then start 1/4 dose

Thanks for the input from everyone
