I think I got most of it out with my normal siphon - I rubber band a fish net over the tube so that it doesn't suck up the Aquasoil. Luckily it wasn't too entrenched in the hairgrass. I'll post pics in a bit.
I was running 2x T5HO for 8 hours, I think it's too much light and the combination of light + ferts caused the bloom. I disconnected one of the bulbs and I'm going to try 1x T5HO for 10 hours instead... The bulbs are about 16" from the substrate, and I believe each bulb is producing about 38 PAR, although it's hard to tell without my own PAR meter - I'm basing this from Hoppy's data which he collected from someone with the same fixture as me.
I've heard I should be shooting for between 30 and 60 PAR at the substrate. 2 Bulbs would have put me around 76 PAR which is a little high. 38 PAR might be a little low, but it might also be nice not to have to trim every week... lol
