It's still working great for me, the only plant pearling is Bolbitis, imagine, Bolbitis pearling, this stuff sat dead in my tank for six months and now it starts pearling!
I'm not interested in my regulator going bad, Canadian customs brokers dinged me 40 bucks(Ups brokers, sue me, its a fact) cdn to get the bloody thing across the border and I don't want to do it again.
I attempted running the CO2 into the powerhead for the first five days and managed to get the pH down. Today I've started running the flow backward through a gravel vacume(with a limewood airstone) with a 301 powerhead driving the flow, it's adjusted to about 65% flow. I'm hoping this will reduce the 'cloudy' appearance I had before.
Also, I'm using Mineral Oil as the fluid in the bubble counter, it slows the bubbles a bit, but at 2.5 per sec its a little hard to keep count. Question: Are all bubbles created equal? The mineral oil is denser, does this mean my bubbles are bigger than they'd be in water? I think so, so I'd estimate by bubble rate to be a bit higher than I''m counting--ANY IDEAS???
