Those of you who've done iwagumi layouts...
...do you start the tank out from the beginning with a crapload of stem plants, and then gradually remove them as the carpet fills in? Or do you start from the beginning with only the carpet plant, and just deal with the algae as it happens? The reason I ask is I can see that people do it both ways, and I'm a few inches away from throwing my hands in the air and planting a buttload of rotala all around the edges of the tank.
As of right now, I'm keeping things in check, I believe. But there are an awful lot of diatoms growing in there, every day, and it's more than the otos and the amanos can keep up with. Also, there is a lot of green dust algae growing on the rocks, but I actually don't mind that so much because it's pretty. But in the last week I've noticed thread algae starting to make its presence known, so I mowed the grass down to the substrate, hoping the cleanup crew will start munching on it.
I'm just starting to get slightly anxious about this setup, and looking for some bits of wisdom from those of you who've been through this before.
I'm running pressurized CO2 at just less than 2 bps, which keeps the drop checker at a yellowish-green color. I'm dosing EI style at the recommended dosage (for a 20g) of 1/4tsp KNO3, 1/16tsp KH2PO4, 1/16tsp K2SO4, and 1/16tsp CSM+B. Each of these is 3x weekly, and 50% water change on 7th day.
Oh yeah, and 72w NO t-5 lighting.
