Mmiller2001 Posted May 6, 2021 Share Posted May 6, 2021 (edited) I follow Greggz and try to emulate what he does; as his tank is insanely beautiful. So hopefully this will give some insight to those who want to dig a bit deeper. Burr740 is Joe Harvey fyi.

Brandy Posted May 6, 2021 Share Posted May 6, 2021 Hey that is a cool thing. But I don't understand the pH- column? what do those numbers refer to? Also are all these tanks with CO2 injection? 1 Link to comment Share on other sites More sharing options...

Brandy Posted May 7, 2021 Share Posted May 7, 2021 Ahhh, Ok, that makes total sense. 1 Link to comment Share on other sites More sharing options...

I read another article from Tom Barr; where he said you can use the estimated index dosing for low-tech tanks at 1/3 to 1/4 a normal dosing. FYI What's great about this table is the ratios.

gardenman Posted May 7, 2021 Share Posted May 7, 2021 I was confused by the pH too. I thought, "Okay, so their tanks are filled with hydrochloric acid. Interesting. Not the way I'd do it, but whatever." 2 Link to comment Share on other sites More sharing options...
Streetwise Posted May 7, 2021 Share Posted May 7, 2021 I recognize the username from another forum. @TheDukeAnumber1, is this a dosing schedule? 1 Link to comment Share on other sites More sharing options...
Eric R Posted May 7, 2021 Share Posted May 7, 2021 Also, the Sub column is substrate, here is the key: I - Inert............... E-Eco Complete............ A - Active...................D - Dirt................F - Flourite Link to comment Share on other sites More sharing options...

Yes, and the Parameters they keep...GH, KH and the relative ratios. 1 Link to comment Share on other sites More sharing options...
TheDukeAnumber1 Posted May 7, 2021 Share Posted May 7, 2021 I really like to see how precise some of those tanks are tuned too. I use the "PPS-Pro" dosing mix Edward developed. https://sites.google.com/site/aquaticplantfertilizer/pps-pro 1 Link to comment Share on other sites More sharing options...

But interestingly, my EI is getting leaner! 1 Link to comment Share on other sites More sharing options...
gardenman Posted May 7, 2021 Share Posted May 7, 2021 I wonder if anyone has ever taken a PAR reading in a tank outside under the noon sun to see what the absolute maximum PAR should be. The guy with the PAR of 163 might just be brighter than the sun. Link to comment Share on other sites More sharing options...
Isaac M Posted May 7, 2021 Share Posted May 7, 2021 Hi @gardenman, there is a video that I could not find unfortunately of when Cory did exactly that in one of his old outdoor ponds. If I remember correctly, the par reading was way high though. It was not even comparable to our aquariums with artificial lighting haha hopefully someone knows which video I am talking about and they can link it here.

Eric R Posted May 7, 2021 Share Posted May 7, 2021 I think that most commonly when we use PAR for planted tanks, that the units we are measuring in are micro-mols per meter squared per second, which is equivalent to the slightly more accurate and technical term PPFD (photosynthetic photon flux density). If that's the case, then yes, sunlight has a much higher ppfd than even the strongest planted tank lights (at least according to this one source I quickly found): https://www.ledtonic.com/blogs/guides/sunlight-ppfd-measured-over-an-afternoon Video about units for PAR vs PPF vs PPFD: I feel like we should start saying PPFD instead of PAR, but I've never actually used a PAR meter and don't know what units they give for results. I know that on plantedtank.net, I've started to see PPFD used more, though PAR is still commonly in use. Link to comment Share on other sites More sharing options...
