I have done vodka and sugar dosing on and off for the last few years. I mainly did it when phosphates levels were not optimal.

Recently, I read an interesting thread with Dr. Harry on his success with dosing, solid vodka with Bio Pellets. I am testing this out now. I get tired of manually dosing with Vodka, and have heard of a number of dosing disasters, so I need to be careful.

However, using a reactor with solid vodka dosing, is something you set and forget for 1-2 months. I like doing this approach and will see how it goes.

If it is successful, I plan on increasing my bio load on my tank. I always believed in a low bioload, but do like the look of a lot of fish in a tank. So I will test this approach and see how it goes.

PS. I am one of the guys, that has had problems with my DSB and Vodka dosing. So I reduced my DSB, to around 1-2 inch depth and plan on keeping sandbed low.

Within a very short time, my nitrates were back to 0, However, I think the real solution, was to remove the DSB.

Matt,

I have had my sand bed cause problems twice. Basically, here is what happened. After I have fed fish very little for a while and did large water changes, each time, phosphates came back in about 2 days. Did use a GFO reactor.

After trying everything, I removed 1 inch of sand, from all parts of tank. I first vacuumed it, and later just used a strainer.

I noticed huge drop in phosphates the first time around, and the 2nd time around, 6 months later, nitrates and phosphates went back to 0.

After contacting BRS tech support, we chatted about my generalization, that people with very deep sand bed did fine. People with 1 inch of sand same. It's the reefs with 3-4 inches ( meaning not very deep ) , where you are kind of in the middle is a problem.

This is just my opinion.

However, for me, my parms, went quickly to 0, each time I removed a layer of sand... That is not in dispute ( for my tank... )

I've been dosing vitamin c for about 2 months now. I had problems with brown slime that almost overflowed my tank when I started dosing but since then I'm more than happy with it. All my zoas look healthy and I didn't have a single zoa melt issue. The best part is that my nitrates and phosphates stay really low, nitrates between 0-5 and phosphates undetectable. And that's with a slightly overstocked tank and everyday feedings.

I think you're on to something. Over the past few days I removed the 1 inch sand bed out of my 40 breeder. This morning I took the bucket and threw it out in the garbage outside.. the smell was almost unbearable, even in the open air. That was from a small sand bed in a relatively young tank with a low bioload and good skimmer.

I can't imagine what accumulates over time, even if some is broken down. The smell alone was enough to make me 100% certain barebottom will be right for me.

Those that have a DSB should really be careful with any type of ULNS systems.. from Zeo to vodka to pellets.. A lot of problems w/ users going to a ULNS tank can be attributed to having a large amount of organics in their sand bed, from everything I've read.
