Thanks! I can't remember which 3 I have.

I decided to just stick with Robert's Oxygen. Everything else is minimally a 30 minute drive from anywhere I frequent (Laurel is probably closer to an hour).

Where near Damascus/Gaithersburg/Rockville can I fill a CO2 tank?

Robert's Oxygen will exchange it, but it's partly full, so I'm not sure that exchanging it makes sense.

Ah, yes, I have a handful of them, plus RCS. I like Amanos though, so there's probably not much harm in adding more.

Spyrogyra can be a real pain! You can also combine treatments of Excel and H2O2. Again, don't overdo it though. If you have something to stimulate slime coats on your fish, it's not going to hurt adding at the same time, but isn't necessary if you do in small doses. Thanks, I do have some of the Ko...

Just try a small area first, turn off all flow in tank (filters, powerheads, etc.) It may bleach the moss, but moss always comes back. You can combine these treatments with some blackout days, leaving the lights out completely. Some people claim success having a siesta too, running the lights for 4...

If the algae is mostly focused around your moss wall, have you tried spot dosing with H2O2 (hydrogen peroxide) several times weekly to try to inhibit it's growth? If it's spyrogyra, it often likes good conditions so you have to be a bit more aggressive. Looking at pictures on the web, yeah, it look...

Oh yeah, it's mostly on the moss wall. It seems to like filter flow, but grows over pretty much the entire wall... I had some Bolbitis that it was all over (that's the other low light fern thing) and I pulled that from the tank and let my headstanders clean it off.

I've been battling a nice, green, long-stranded algae in my 33 for months. Water parameter tests come out fine, I use Flourish Excel daily, I've even tried keeping lights out for days at a time while dosing with Excel. Sometimes this makes a dent, but it doesn't hold. I've had multiple people tell m...
