Re: [APD] Strange cyano like algae
I am happy to report that I have gotten rid of the strange
cyano like algae just by increasing CO2 back up to the
previous level. No black out was necessary.
I still have a few small patches of the fuzzy green algae
here and there. It looks like real loose green fiber fill.
It has a somewhat coarse texture. I wonder what this may be
and if a 4 to 5 day blackout will get rid of it. Any idea?
I also like to thank Vaughn for recommending the brass check
valve. Two days ago while I was replacing an empty CO2
cylinder for a calcium reactor on my reef tank, I noticed my
plastic check valve was cracked. The rubber piece inside
was stuck and bent. I am going to replace both check valves
with better ones.
Although the brass one on the site that Vaughn recommended
looks fine, I am tempted to order an ADA's Cabochon Ruby.
But then again, I am afraid of dropping it on my floor...
