This is the latest information from Adrienne:
Since carbon dosing BioHome worked so well on my larger tanks, I decided to try it on my 3 smaller tanks as well. I ordered some BioGravel and while I was waiting for it, I decided to experiment and added some BioMax by Fluval to the 3 filters and started daily dosing of sugar. Four days went by with no decrease in Nitrates. Finally my BioGravel arrived and I replaced all the BioMax with BioGravel. Nitrates went down to 0 on all 3 tanks overnight! I was stunned to say the least. This is with no other changes or water changes either. I decided to test for a while longer before sending you my results, just to be sure!
The tanks were 2 5 gal hex tanks and a 2.5 gal tank, with Marineland Penguin 100 filters. There is a good sized compartment after the mechanical filter that accommodates the BioGravel in a Tetra BioBag very nicely. These 3 tanks housed my Molly farm and I’ve since replaced them with a 20L tank partitioned into 3 sections, with a Penguin 100 in each section, to eliminate any dead spots.
I have also switched from sugar to glucose on all my tanks because the sugar solution kept crystallizing and clogging up the lines on the dosing pumps. Sometimes the output line would clog and the line would blow off the pump, sending sugar water everywhere :o( or the input line would clog and no sugar would be dispensed with no indication, causing Nitrates to increase.
The glucose syrup is very thick, so I water it down to a 50% solution so it flows well through the pump lines. Dosage amounts are the same as the sugar solution I was using.
I suspect that Nitrates increased initially in the 20L tank since the the substrate was new and the water volume doubled, causing a mini cycle.
Here is a picture and chart for the new 20L Molly farm.

Biohome Ultimate

Hi, I have been using Biohome Ultimate for a few months now and just
love it! Please add a note to your website, that in order to process
nitrates, carbon dosing is required. I have been using sugar in my
cichlid tanks with success. Nitrates are all 0 everyday! Sugar works
much better than Biofuel and FloraViv. I have not tried Vodka. Didn’t
try vinegar because it would lower my Ph.
I am now looking for some biohome ultimate for my smaller HOB filters.
Will BioGravel work as well? are there any other options for small
filters?
Thanks,
Adrienne
I hadn’t heard of this so I asked for more information.
Adrienne,
Where did you come up with that idea. I’d like to investigate a little more. How much do you use?
And boy, did she respond!
