Vodka is used because it is almost pure ethanol without additives, coloring, tanins, flavoring etc.

Brandy which is fortified wine that spend long period in oak cask for coloring and complexity is not suitable to be used in reef tank as it is not known what side effects it will produce.

Hope that helps.

vodka its really a good sorce my fiji pink birdnest , lime green mille stackhorn alll colour up ,plus vinginer /sugar not frag all big piece the colour is intense,its really socking 0.3ml daily doseage .

guess ill stop using zeovit stuff liao, special thanks to rockyboy for shareing the info:ThanxSmiley:

Solid carbon dosing is said to be safer. However, it must be used correctly.

Polyhydroxyalkanotes (PHAs), like NP-biopellets, are bioplastic polymers produced from sugar fermentation. Biodegradation of PHAs in the presence of nutrients (limiting factor) releases organic carbon. As such, this self regulating process is safer compared to manual dosing of carbon sources like ethanol. PHAs provide the organic carbon for denitrification to occur and also acts as a substrate for denitrification bacteria to attach to.

However, major issue with this is biofloc formation due to heterophic bacterial activity. As such, PHAs need to be kept in constant suspension to avoid clogging from biofloc and to promote a healthy thin biofilm. If PHAs are not fluidizing and get clogged up from bacterial biomass due to insufficient flow, the resulting anaerobic conditions promote phosphorus to be released by the bacterial biomass into the system. This is when you will see increased algae issues if you are using PHAs incorrectly.

It is only under aerobic conditions & anoxic (totally no oxygen) conditions that phosphate gets assimilated by polyphosphate accumulating organisms (PAOs) as polyphosphates. This process involves either oxygen or nitrate, depending on the PAO involved. These PAOs are present in the biofloc that is produced when PHAs biodegrade. You need enough flow through PHAs to drive out the bioflocs to be removed via mechanical filtration (eg. filter socks) or via protein skimming.

Bros , in respond to this, would having a bio pellet reactor is more a safe approach ? I'm setting up my 4ft and purchasing all the equipment one by one . Making sure i have the right equipments before embarking on this.

However i've purchase a deltec denitrator recently and wondering is this sufficient or should be accompanied with a bio pellet / or vodka dosing methods
