Thank you, I've got 4 tanks...
8g - only chaeto and water changes
5.5g - only chaeto and water changes
Biocube - chaeto, chemi-pure elite, purigen
36g - macro algae tank
I tend to do much larger water changes. I do them weekly and for the smaller tanks, I'll easily drain 50% or more per water change and grow the chaeto. I also feed heavily, everyday. Tbh, I've not tested my nitrate and phosphates for a while. I'm assuming both are low, why? Because...
1. My sps corals are extended and growing
2. There is very little algae, other than coraline, in any of my tanks.
When I get home today, I can test a few tanks to see where I stand. Last time I tested for nitrates, it was at 15ppm, but that was before I started the refugiums. I'm curious to see how the numbers are now. I have to pulll chaeto every 2-3 weeks. I pull about that much when I do. My fuges are small. The sizes are below.
Chamber 1 in an 8g Oceanic biocube;
Modded Aquaclear 50
Modded Aquaclear 70
I need to add timers to the fuges today. I'm a bit of a slacker. I try to run them on opposite photoperiods, but sometimes I forget.
Hope this helps,
L
