Even spirulina that is a great shot to compare cell size between cyanobacteria and spirulina

Some long videos.


Dinos very active and moving pretty quick. I tried to get on one but as soon as I found one pinned in a pod scrambled by disturbing it all and it's pretty thick.





You may not see it very well in this but it starts off with some basic filamentous bacteria and in comes this cool club bacilli. In the eye pieces I could clearly see the flagella and pili

Spirulina




Diatoms like Navicula sp surrounded by bacteria some coccus and looked like possibly small rods baccili or maybe Mycobacterium marinum :eek::eek::eek: j/k but that is a serious one and why gloves are good. ;)

Chlamydomonas dysomos. Hard to see the flagellates in the video. Changed the focus, tint and contrast quite a bit to help see them.

nematode moving around and can barely see it covered up is a couple pods. I think I found 3 or 4 pods.


3 of the pods grouped together.

This nematode distracted me and I stared to follow and focusing in and out on it.

So if I do 2 scoops I have 2 days worth here. I'll pick up one more from my LFS. I saw they had some in stock.

I've turned off my automatic water change.

Ozone offline

I've cut carbon dosing in half.

I've pulled GAC out. (I don't use GFO or any other PO4 binder so nothing there to pull out.)

I opened up the skimmer lowering the water level a lot.

ATO is still on.

ATS is still on

Limewater dosing still on.

Light schedules unchanged. (I don't believe in blackouts anyway.)

Feeding schedule and amounts still the same.

I think that's it.

I grabbed a 1L container and filled it with 700ml of tank water.

I had calulated out exactly how many milligrams of the 70% active ingredients in MetroPlex I would need for around 200g total system volume. Using the little spoon I started putting some in that container. That little spoon was a pain. I went for a better measuring device and then decided to just dump the contents completely in.

So, 5g day one done.

Thanks! I need to give it a good cleaning now too. It's been taken apart and put together, in and out of its original box, and through some demolition and construction now. I'm so excited it can remain setup now and under a dust cover.

Following along...another info packed @jason2459 thread, with tons of stuff I will in no way have time to fully comprehend :oops:

Thanks. After reading up on metro a bit I got excited and saw an opportunity to have some fun with fairly low risk. A tank full of cyano and dinos don't bother me one bit. If anything has a negtive reaction I just have to turn on my ozone generator and GAC and the metro will quickly be nutralized.

Fyi, I have 2 days worth of metroplex if going forward with the double dosage of 250mg/10g/day. I was going to get another vial of metroplex but found this and gives plenty to play with on the side now.

Another alternative and can be found on amazon.com
