All very good signs; those are some easy indicators that the CO2 is headed in the right direction. I can't see the flow myself so I can't comment in detail, but hopefully this will leave you to mild adjustments rather than fighting with the tank as a whole._ReApEr;43905 said:The GDA, staghorn, and fuzz alga all seem to have disappeared.

I was told that it was growing immersed, if that's any clue.
Looks like a Marsillia spp. to me.
Ya, HC is that way unless it's in rock wool or done as DSM. Perhaps try netting it down if uprooting continues to be an issue?_ReApEr;43905 said:I'm having quite a time trying to keep the freaking HC in the substrate. Otherwise, this experiment of mine looks promising.
It's probably not the nutrients, but adding more definitely won't hurt; more PO4 does tend to keep the GSA down. As dutchy says, it may be another waiting sort of thing. Planted tanks have taught me long term patience and timing like nothing else._ReApEr;43905 said:and GSA running rampant, though. Another precaution, I guess you could call it, I've taken is I'm now using "rounded" 1/4 and 1/16 tsp measurements as opposed to flat ones, just to make sure the nutrients really are non-limiting. I also did another butcher round on the Bacopa this week and am continuing to slowly hack the algae-infested crypt leaves.
