I would like to know about anyone elseís experience with Eco-Complete vs. Seachem. Iíve kept up to 6 tanks, 5 with Seachem, 1 with a combination of Eco-Complete/Seachem mix. All other tanks grow like crazy. I have always struggled with the Eco-Complete/Seachem mix tank. I had forgotten about this difference, until yesterday. Iíve come to the determination that this must be the problem. Now Iím seriously considering changing the substrate on this tank, no small feat, even though itís only a 47G. The question is: Anyone else having this problem? Other that removing all the fish/water then scooping and wet-vacuuming the substrate, any other quick ways to do this. Iíve done it twice, and itís not fun!
I haven't had any problems myself and both products are very similar (inert iron based clay) so it might be you got a-hold of a bad batch of Eco which is known to happen from time to time.
Unfortunately I don't think any way of changing it out is going to be fun. I would recommend moving the fish to a heated bucket(s) and changing it out slowly in small chunks if the tank is planted or just break the tank down fully if it's not.
