Chemi-Clean has been known to crash tanks. I wouldn't dose it again. The effects tend to be temporary, in any case.
I've used chemiclean years ago,I wouldn't use it again particularly when I was trying to grow bacteria . Siphoning,less food and cleaning up the water get rid of it as noted above. You need to siphon out what you can when using chemi-clean in any case.Some cyano has toxins which I suspect could be released when it dies .
FWIW I've been dosing vodka for 2yrs with only minor patchy cyanobacteria early on; none since I added a bit of vinegar to the dose .
Actually sugar is more potent than vodka since it has no water in it. It is roughly 2.5 times more potent in terms of carbon content than 80proof vodka which is 40% ethanol and 60% water and roughly 20xs more potent than vinegar which is 5% ethanol and 95% water.
Dilution is not the only difference ,however. Each of these carbon sources create different bacterial activity and by products. Sugar for example has been known to cause difficulty for corals which has been my experience and there are several studies linking elevated glucose levels and coral disease.
I believe I figured out my issue with the EcoBAK. I've been running the EcoBAK since June '10 along with GFO. I had issues with elevated PO4, but after running them they're now down to 0.00 on my Hanna Checker. I was adding a 1/3 lb of GFO weekly, then switched to monthly. This helped lower my PO4, but the EcoBAK never appeared to be dissolving.
I think the GFO was eatting too much PO4, so the EcoBAK didn't have enough to utilize. I removed the GFO and just kept the pellets running. I noticed that the glass algae started to come back almost every other day. But now after a month of running just the EcoBAK, the glass algae is now taking like a 5 days to return. Plus, the PO4 is still testing 0.00 on the Checker. So, looks like my setup may finally be GFO free. Which is what I was hoping for in the beginning.
IMO it is much simpler than daily dosing and is very cost effective.
Bill:wave:
Been dosing vodka for years. I stopped dosing a month after putting the eco bak online. Two months later I had an algae outbreak and had to resume vodka dosing. I'll leave the pellets online for a bit longer and hope they kick in and start working, but so far its been a disappointment.
