Yes I know I posted something about cycles a while ago (maybe years) but I am going to do it again. I need to get my mind back on fish stuff.
Anyway, after a great many years looking at this stuff I noticed that things, mostly things perceived as bad, come in cycles.
I really don't know why but I would like to put it up for discussion.
If your tank is only a few years old, you will not notice this but after a decade or more it becomes noticable and not just a little. My reef has gone through more cycles than I can count, now it is in a clean cycle. I don't remember when the last time this happened but my rocks are very clean.
This does not seem unusual but taking into consideration that some of them have been in there over 35 years it seems wierd, unnatural and unhealthy to me.
The tank is also going through a mushroom coral phase, they are multiplying all over the place and the hard corals are declining. I have noticed this many times. Sometimes the soft corals like leathers, colts and star polyps take over and grow out of control. Sometimes it is gorgonians. It seems they all can't grow together. I am sure it is the chemicals they exude and apparently skimming and ozone does not remove them fast enough or even at all.
These cycles can last a few years but these events are not just barely noticable, they are very noticable. All of the hard corals, mostly LPSs in my tank shrink to the point that they disappear while the softies grow immensely.
Hair algae is another one. That stuff can grow all over the place for a few months, then disappear, not to be seen again for a few years. No, phosphates, nitrates and Myley Cyrus does not give you a hair algae cycle. I know that that is the current wisdom but it is wrong.
Every tank with fish and corals has the capacity to grow hair algae. It grows mostly in new tanks which are the cleanest. Fish eat, they poop and they exude slime, our corals have algae growing in their tissues. Excess nitrates will let algae grow nice and thick but the stuff can grow with almost no nitrates. My nitrates now read 2ppm which is plenty to grow algae but I have none.
Here is a picture of my tank in the 80s (I think) see how it was covered in hair algae
The stuff goes away on it's own. You can throw rabbitfish, snails, blue legged, red legged green legged, no legged, bow legged or peg legged crabs in there with sea hares and yes, eventually it will go away. It would have gone away anyway but I know most people don't believe that and those sea hares need a home anyway.
After the algae dies for whatever reason, it will probably stay away for a few years but just when you least expect it, Wow, hair algae.
Why? I don't know.
Cyanobacteria does the same thing. That stuff can cover a tank quickly and it is not an algae so it may take longer to leave, if ever. I always have some of it under my gravel. I find it kind of colorful, as long as it stays there.
So now I am in a delema but I have huge soft corals. I know enough to stay away from LPS corals at this time as they will not prosper. I also know it is the time to buy some mushroom type corals because there is no way they can die at this time.
Pretty soon this guy which is about 13" will take over the tank and I have found a few more of them that I did not buy so they must have came from this giant.
I don't know where I am going with this but this hobby is not cut and dry. All is not what it seems and our test kits will give us no incite as to what may happen. As for now "luck" is the only thing we can assume will get us through these cycles, at least until someone figures out how to eliminate these chemicals which I feel come from corals in their effort to thrive while eliminating competition. We need a way totest for these things, if these things actually exist or maybe they are only a figment of my imagination.:crazy1:
See this red stuff from last year? No it is not cyano, this is what I strive for. A healthy coating of short algae. This stuff is from the Long Island Sound
