Quick Question - sorry this is probably a dumb one too, lol :icon_bigg Anywho, my current substrate is a 2:1 Eco-Complete to Gravel mix in my 55 gallon. Tank has been up around 3 months, loaded with plants & fish, everything doing great. I'm wanting to add another bag of Eco-Complete to create a slope section around my driftwood pieces - can I do this safely without causing parameters to go crazy? I was thinking of using a plastic cup to scoop out of the bag, lower into tank, and gently pour directly over the area I am wanting to add to. Thoughts? Suggestions? Criticisms? Insults? :bounce::bounce::bounce::bounce::bounce::bounce::bounce::bounce::bounce::bounce::bounce::bounce::bounce::bounce::bounce::bounce:

Doing it in steps of 1/2" or less is without issue that I know of. Going too deep all at once can smother the bacteria though. I've added over an inch to an existing tank doing it in steps over time.

Awesome - thx wkndracer! My thoughts were that since I was only thickening a small portion of the bottum (probably a square foot area of the 55 gallon) instead of trying to cover the entire bottum, that it would not be an issue.

You'll be fine putting it in. I would say 95% of the bacteria live in the filter anyways so the bacteria growing on the substrate can be ignored. Just remember to keep the bag of water clarifier that comes with the eco. You will cloud up your tank pretty badly with the eco but the clarifier works great to clean it up within 12 hours.

Well, I went ahead and added the substrate and everything looks great. The reason I added btw is that the driftwood pieces are attached to rather large flat rock pieces. The substrate over the rock was a bit to thin to really plant anything in, so I really just wanted to thicken the base around the driftwood so I could plant... I used a plastic cup, lowered slowly to the bottum, then poured in the desired location. To be honest it really didn't even hardly cloud the water, within about 3 hours it was back to clear. I can understand how it would be a problem if you were trying to recover the entire substrate, but I think if you are just adding a slope, or filling in a section you're not going to run into any problems, imho.

I've actually done that with flourite. Rinsed it like crazy with as little agitation as possible. Lowered it very slowly and watched as the dust cloud drifted toward the filter. The water was completely clear in a few hours.

The vast majority of "knowledge" in this hobby is surmised by experience.
I would be curious to know exactly how one gains experience into the percentage of microorganisms living in the substrate compared to the filter without doing cultures from each and comparing the cell counts.

"I would say" means exactly what it says, and there's nothing wrong with that.
There is something wrong with it actually. Thats how myths get started in this hobby. The next time it gets repeated it loses the "I would say" and becomes fact.

I think you're blowing this out of proportion. YMMV.
