The Chemiclean treatment worked like a champ in this tank. No sign of spirulina after one treatment. I did a 35% water change last night and started running some carbon. There is still some brownish film growing on the glass and a touch of sickly looking green bubble algae coming back on the heater. Overall the tank is looking much better though:
You can see my home made surface skimmer on the right side. It's ugly but I'm amazed how much crap it has pulled out since the Chemiclean treatment started. That little filter pad is nasty brown every day. It's got me thinking if there's a way to modify the Aquaclear intake to surface skim instead of pulling water mid way down the tank.
I've dosed KNO3 the last few days and tonight both the 20L and 40B tanks test 2 or 3 ppm. I'll probably hold off dosing more and see if they stabilize.
This Saturday will be 2 weeks since the last Vibrant dose. I may try doing a maintenance Vibrant dose every other week for a while to keep the bubble algae at bay. I may also hold off another week or two and let the nitrates stabilize first though.
