reef-pi :: An opensource reef tank controller based on Raspberry Pi.

Heres a few tank pics, no discus, but how bout angels and tetras...and yes there are some glofish, have to keep the wife happy. Sorry the vals need trimmed, they are my nitrate removal system...i trim them back to tank height once a week and throw away a 2 gallon bucket of trimmings once every 2 weeks. I dont fertilize or do co2 instead using the fish to fertilize the plants in return for being able to overstock big time!

Man that’s awesome!! Totally amazing!

Awesome tank, and yes, happy wife == happy life

I have not tried any of the hats yet, I have @wykat 's hat that I'll have to solder when I get time (busy with apartment move right now). The hat you are referring to is designed by @Michael Lane , his build thread is here , he is also one of the code contributors who did a significant amount of work to improve the reef-pi UI as part of 2.0 release.

Thats great so buying that hat means I will be helping out someone who helps with reef pi! I didnt connect the ML reefkeepers with Mike Lane...so I already know the hat will be nicely designed one. For my tank its perfect and lets me focus on other parts of the build.

For running reef pi headless is a pi zero w adequate or would I be better off starting with a 3A+ or B+ for future features on the horizon?

Pi zero is more than enough for headless use

Very nice looking tank!
I set up a 55g freshwater for my wife. It's more of an "artificial" set up as that's what she likes. Strangely enough, I still do not have a SW tank set up yet and l, due to financial constraints, probably won't for a while.

I’m thinking it’s time to step up the build on my reef-pi

What happened?

@Ranjib

Hey so keeping an eye on cpu and memory use since I’ve been monitoring temp there is a steady increase of memory use. Is this normal? I was assuming that is was showing ram stats. I assumed that tam usage would stay consistent for the most part.

It will be cool to have a similar lcd (16x2 char) support in reef-pi

It’s nowhere near to be concerned now, but yes ideally memory should never creep up. But that ideal, in reality the Linux is running more than a dozen process and and it’s highly unlikely all of them act ideal (including reef-pi). Hence, you’ll see such memory creep, but they should show some pattern and die of after a time (gc, restarts etc) or hit a plateau sometime it takes couple of weeks to observe this pattern. As long as it’s not hitting the roof (say 100mb ) you should not be worried

What happened?

Nothing, yet... but every time I do a water change the screen gets goofier and goofier looking. I don’t trust it right now. I am very close to finishing my build at least my interim build while I build another lol.

That would be cool. Is this something in the works?

Nothing near time :-/ . Have our priorities lined up. But this is relatively easy, i had started working on something similar, I have the driver code etc ready for it but never integrated it with reef-pi.

Is it just me or does that error code look like a dog getting rained on?
Hope it lasts till you get your reef-pi online.

This is a Amazing tank .. We have a 40 gallon breeder (gupply land) Planted tank as well as the 240 reef tank...

Welcome to the REEF-PI Controller thread and REEF TO REEF.. There are some very talented and amazing people in here awaiting to help you with any issue you have ..

Good Luck ...

Continuing on this topic, here are the CPU/Memory stats of some of my builds,

ph Monitor, powered by pi zero

One of the all in one controller on pico tank (I call it bozeman), powered by pi 3

Kessil controller (controlling 3 kessil lights) powered by pi zero

As you notice, all of them shows memory usage creeping up. Some of it is expected as reef-pi stored more usage data as time progress for first one month, by design (things like temperature, ph etc). It's nowhere near a level of concern (12-18 MB). I'll keep an eye on this.

Awesome appreciate the response @Ranjib.
I just wanted to make sure it was normal.

Mine is not at 100, but it has definitely been a lot higher than it was on 1.3 that I just switched from.
I'll keep watching for the time being.

So,. you get periodic spikes of CPU at 40%, but the overall trend is well 20% (second graph). Do you have lot of timers or things that all trigger at the same time? like 0 second.. whats the interval between the spikes in the first graph?
