Sonny, Im not sure exactly on the prices of all the salts here in NJ, but I know for sure that the Brightwells at 65$ is the most expensive I have seen here. I bought all my RC from DRSfosterssmith with an old coupon code (that I googled for) and bought 3, 160gal buckets all for under 100$ So all that salt took me a while to burn through.
Last night I did another 35 gal water change. I have done 1x 15gal, 1x 30 gal and finally my 35 gal water change last night in one week. All seperated by a day or two, running a 75gpd RODI.
I am trying to get my nitrates to zero, for some reason my nitrates were almost at 40. I am not running any MB7/vodka at the moment. With my second water change my nitrates were down to 10. I have not checked since my last 35gal water change last night.
I just want to emphasize on Sonny's statement about cleaning your powerheads. I got my first vortech MP40w on 25 August 2009 (my birthday) and I did not clean it until yesterday. Before I cleaned it, I was trying to make a decent wave and I noticed I could not, so I cleaned it and wow, I cant run a decent wave without it almost overflowing my system, Cleaning that vortech at least upped the power and output by 50% at least! I was overwhelmed and stoked on how much gunk was in that vortech that I couldnt see until I took it out and cleaned it, The flow is almost twice as powerful now that its cleaned up. and that was just about 2.5 months worth of use without cleaning. I usually clean all my pumps quarterly unless I see it fit to clean beforehand, I will now be cleaning my vortech monthly, Thanks Sonny!
