eco doe not raise pH. What likely happened is that the co2 gassed out of the water column.
Using EcoComp in 2008 I didn't record any shifts. On 2 tanks in 2011 I indeed did in fact see it happen and scratched my head seeing it.
Tested twice to verify the results (noted it in the tank log). Checked the titration kits against standard too.
Played the tanking game long enough to see pH altered daily by CO2 in both directions. What happened was a buffer release into the water and it was a 2-3dKH rise twice and a 1dKH rise the last time. My tanking water is 100% RO with the mineral content established to known values. The only unaccounted contributor was the new substrate. I'm not the only one to note a rise in buffer using EcoComplete within the last 12 months. Forum search if you feel a need to validate it, I personally don't see it as that great an affront.
That is rather ridiculous. Eco complete has no nutrient soup anything. It is simply packed in water for the live bacteria. All the minerals are in the gravel itself.
Your English here is a little hard to understand... but if I understand it right, you think clay gravel can't do any better at providing ferts than adding it to the water...??? And yet you think "dirt" is somehow better?
ECO COMPLETE ABSOLUTELY DOES NOT CLOUD YOUR WATER
You do not rinse it, ever, at all.
I put Eco complete right out of the bag into an aquarium and added water, and PHOTOGRAPHED IT step by step. The water remained crystal clear. See for YOURSELF
As far as altering the pH, yes, most any substrate will to some extent, and I have never read comments from anyone else that this is a problem with Eco complete. Turface is much more alkaline.
Eco complete other than being a bit pricey, works GREAT.
CaribSea makes the published statements about the product not me.
Within the short posts I made in this thread I never said clouding was an issue. Also all the EcoComp that I've used was directly applied without rinse or other preparation.
The bold text in my post is straight from the CaribSea listings on the product. So while my English on a reluctant response may be poor it's the claims by the company that are rather ridiculous (imo)
Using Flourite Original or CaribSea Eco Complete (either one) without supplements being applied with regularity to both the substrate and the water column have provided very poor results in my planted tanks.
The journals on those tanks contain the maintenance/dosing cycle used to gain plant growth. Flooded 5/9/2008 and 5/13/2008 neither were self supporting beyond 30days. Both require supplements. Neither will even grow common crypts without help. While the mileage of others may vary that is what I experienced on those tanks using the material AND still do. I dose on a regular schedule and achieve results I'm happy with. Without the scheduled dosing plant health suffers in short order so I don't see the substrate supporting the plants.
Characterizing Flourite Original I would describe as it a fired clay product as they indeed advertize it (crushed up brick).
CaribSea's Eco Complete appears more along the lines of a fine lava rock type material in appearance rather than a clay based product but honestly (IDK).
And again, without a scheduled dosing of ferts plant health suffers using either.
Tanks using potting soil as a base layer of substrate lasts years here for me without further additions and NO SCHEDULED DOSING. So yes I feel 'dirt' is better based on in my hands, seen by my eyes results. How long will these dirt tanks lasts? I don't know yet because the oldest is 3yrs wet and still growing plants whether it has 3 adult fish fed every other day or 25 young fish fed twice a day. I can't justify tearing it down because it requires almost no attention and confronts me with no drama. Rewarding me with stable, healthy plant growth year after year. With your knowledge of Walstad's methods and published works I'm somewhat shocked by you're challenge to the results it provides.
"Containing essential nutrients, including iron, calcium, magnesium and sulfur in addition to over 25 other mineral supplements,"
wow! jamb packed with goodies according to their claims.
"CaribSea Eco Complete contains a live Heterotrophic Bacteria"
How is this possible?
How does it survive months bagged and boxed on warehouse and store shelves?
I can't but wonder about this claim.
"Heterotrophic Bacteria, heterotrophic cells must ingest biomass to obtain their energy and nutrition."
