Carbon dosing - method testing started

Thank you Magnus

Thank you antole


update
today was 1st day dosing with 0.1mil of Vodka on tank 2
other tanks , no changes

1st indication and I will await until weekend when hopefully what I am about to say will be more visibly noticable on images

all the tanks recieved an algae scraping on viewing panel, and 2 internal panels on Saturday, using a credit card to achieve this

observations thus far
today
Tank 1 - which has the GFO, the viewing panel is still reasonably clear
in fact you can see lines of micro algae that I missed with the card Saturday
Tank 2 - Vodka - also reasonably clear
Tank 3 - Bio Fuel and Tank 4 - Bio Pellets - the glass is very dirty already

all tanks have Bubble Magus QQ skimmers
and give or take a few MMs collected about the same in terms of QTY and quality of skimmate

today the cups on skimmers on tanks 2 (Vodka) and 3 (Bio fuel) are noticably darker in coloration than the other 2 and in fact darker than they have been on previous occasions up until now

again I will await weekend before showing images, as the more liquid the cups collect, the more obvious the difference should appear on images

always a pleasure to follow your work steve, thank you for the effort

 

thank you lukabrasi

well earlier than expected here are 2 images showing the differences in skimmate


lined up for image capture in tank order 1 on left - 4 on right


for this image cup from tank 1 was moved in front of cup from tank 2
and cup from tank 4 was moved in front of cup from tank 3
in order to faciliate a better over head shot, displaying the colouration of skimmate differences between the 4 tanks

the skimmate on tank 1 with GFO - is greener than normal, which may indicate its skimming out decaying algae
the skimmate on tanks 2 and 3 , with the Vodka and Bio fuel respectively is much darker,

the skimmate on tank 4 - is also relatively pleasing as is much darker than I expected based on the 1st couple of days monitoring

Steve

 

wow, tank 3 is really putting out some dark frothy skim mate, so cool! intresting about the results in tank 1 w/ gfo- greener than normal makes sense though. i wonder if it's ability to process other organics is affected as it aggressively skims the dead algae....?

 

Man I just read the all 13 pages. Great work Steve. Can't wait to see the results.

 

thank you lukabrasi
yes tank 3 Bio fuel, being used based on the 5 mils per 50 gallon heavy dosing regime - which equates to 1 mil in the 10 gallons of water in there
so far producing skimmate a bit darker than the Vodka, but its only 0.1mil of Vodka at present, which will double on Saturday to 0.2 mils
the skimmer may be overloaded with the decaying algae, I think I will be removing this one Saturday and cleaning it out as I can see a lot of algae trapped in the body at present

Thank you Supernova26
glad you enjoyed it

We would expect the tank with the bio pellets and biofuel to take longer to kick in right?

Instead of adding the food to feed the bacteria that already exist, you are adding the bacteria that still need a food source right?

 

Thanks Cheryl

I would expect the tank with the bio pellets to take longer- and this seems to be the case
I did expect that under initial dosing the Bio Fuel would be pretty immediate - simply because it was the 1st product I carbon dosed my 5ft with, and within 1 week, I noted a decrease in amount of glass cleansing required

I expect once the Vodka dose is ramped up so thats its on a par ( I believe this will be next week at 0.2 mils) with the bio fuel in terms of strenght of solution being added , it will be equal in performance

bio fuel is a carbon source, just as bio pellets are, just as Vodka is and as such what they should do, is create additional free carbons so that my existing bacteria can multiply due to their presence

the bio fuel and vodka will be quicker, because they are being added direct into the water column and as such have a more immediate impact on the bacteria that they come into contact with

the bio pellets will be slower, as they require bacteria to populate their surface initialy before any multiplication can take place

none of the tanks are having any bacteria of any kind added (no MB7)

Great work getting this going Steve. Very exciting!

Thanks Steve,

Yes you are right, I was thinking complete along the lines of MB7.

On that note, bio-pellets is the medium or substrate, made of polymers, does it actually provide carbon or just the medium for growth and disbursement?

TIA
