Allright, I know that all of us at one point or another have battled nuisance algae. namely cyno.
I decided to do some homework and see what I could find to pass along to you guys. I actually learned quite a bit about this.
The thing that I found out that is the biggest help in eliminating these nuisance
diatoms was to actually promote the controlled population of
diatoms!!! BEAR WITH ME!!!
Most aquarist intro to
diatoms is as an unsightly reddish brown coating of their sand and rocks in the first few weeks of a new tank. at that point, most of us decide that
diatoms are a bad thing. and from there on the battle began. When
diatoms are out of balance (like a bloom) they dont do anyone much good. but when
diatom populations are in a stable balance with other proceses in your tank, they are very good for the whole system.
Good thing:
Diatoms compete with blue green algae for resources
Diatoms are much easier to remove from glass and acrylic and less unsightly than blue green algae.
diatoms are part of PLANKTON and just like planton products that you can buy, they provide a healthy natural food for filter feeders.
Diatoms consume
nitrates and
phosphates from the water column and fix them into their tissue where it can be filtered out of your system via your protein
skimmer.
Diatoms on your sand are some of the best possible food for your cleanup crew and are likely to contribute to their longevity and increased health.
I am not going to go into how to dose sodium silicate, if you want to know
PM me and I will tell you how to step by step
A couple other pointers
In any closed environment with animal life and light you are going to get plant life. Our tanks are not exception. so the only choice is whether you get the plant life you like, like corraline algae,
macro algae, sea grasses, mangroves, or corals. or you get the plant life you dont like such as hair algae and cyno.
Every bit of
ammonia,
nitrate,
phosphate, toxin, heavy metal, and carbon dioxide consumed or bioaccumulated by plant life you like is one less bit to feed the plant life you do not want or to adversly affect other life you like.
As long as the speed of
phosphate removal is greater than the speed of production, all nuisance algae will eventually have to die off, as the
phosphates are removed from the system.
the 2 things that confuse aquarists are that:
1. the resulting die off of algae takes time
2. zero test levels from the water column is not the same as zero production, or uptake, of
PO4
The aquarist needs to enable the system to dump
phosphates BEFORE they can get used by algae, if 5ppm of
PO4 is produced, and 5ppm uptaken by algae, one will still test a level of zero, as this only measured excess that builds up in the water column.
The easiest way to eliminate one major source is via RODI water
the second, is to use a
phosphate sponge, like phosguard, or rowaphos.
Since algae require
phosphates to grow and thrive,
PO4 removal is not only the true root CURE its also the least complicated treatment around, for dealing with nuisance algae.
Clean up crews (especially snails) merely recycle the algae, releasing the
PO4 in their poop, to begin the process anew.
combine that with what most of us allready know:
increased flow in the tank
a good
skimmer
not over feeding
and that nuisance algae is a lot easier to get a hold on than you think.
sorry for the long read. thanks for tagging along!!!
