Setting up my second loach tank.

  • We are currently upgrading MFK. thanks! -neo
I have got a water drip continuously onto the surface of each of my tanks. As well as other function, provides surface agitation in case of power cut.

I am envious; sounds perfect. I wish my circumstances allowed me to do something similar; I'm sure there are many others who are also unable to enjoy a constant-drip system, so for us, bubbles must substitute for drips. :)

I drip water in continuously. And on the other end in the sump, I have an overflow to waste a few inches above the return.

So I get a slow and continuous water change. Never do water changes as such.

If I have lots of live food, I might up the flow from a drip to a slight stream.

It is a good system that works for me, but, you need fresh water (unchlorinated) and waste drains situated close.

Oh yes, and for no water chages, my nitrates: 0.
 
I personally tested the oxygenation of the tank on my 75gal.
I was always told to break the surface of the water. Always had bubbles or spray bars.
Once I had good movement with circulation pumps, I lowered all outlets with a flow that would move the surface but not break it.
The fish were fine for over a month. Only when meds were added and a mishap with extra oxygenation did I lose any fish.

You should be fine and we all do tend to over think our setups and often way over-engineer.
Set up the tank you really want and you'll enjoy it way more for way longer.
 
Great to hear. So I most likely won't have to stress over agitating the water's surface.

Speaking of low surface agitation, I found out yesterday and on Thursday how easy this tank is to slightly overfill during the fill up parts of cleanings (as in, the middle brace and lids touching the water), having noticed because the original surface agitation of the pumps is noticeably reduced by the lids and brace touching the water.
Not sure why it is so, but I'll have to take care to not fill it up to that point, regardless of whether I need agitation or not.

The only reason, in my opinion, that you need surface agitation is you have a stocked tank with large fish like CA and SA cichlids, or like me, you don't like the film on the surface and agitation gets rid of that quickly.

I also fill tanks years ago up to the point where the centre brace impeded surface flow. To mitigate this, you could put a thin strip of paint around the front and sides of the tank. Once water line reaches and just passes it, you know you good and there is still space for the surface movement.
 
Come to think of it, there was quite a bit of unsightly film when I turned off the pumps for cleaning the tank yesterday. Agitating the surface ought to keep it at bay, so even though I don't need it for oxygenation, it will make the tank look much nicer.
 
Mildly irritating update. The online store where I was planning to get the roseline sharks is now all sold out of the 5cm size I want, and given their sporadic availability, it may be quite a while before they get them again.

They do, however, have 7-8cm individuals available. Which, depending on the below criteria, might be a good choice.

Question to those who have bought this species at 5cm sizes or smaller: How fast did they get to 7-8cm?
Even though roseline sharks are slow growing, I was thinking they might be faster growing when small, and perhaps fast enough for 7-8cm individuals to not have much less lifespan available than 5cm individuals.
 
Thanks. Looks like getting the 7-8cm individuals would be 6 months to a year down the drain, then.
I'll hold out for 5cm individuals in that case.

Boy, that growth is slow even when they're small.

EDIT: There is a much more positive update for today! ?
Fed the 110 liter some live mosquito larvae, and the remaining Odessa barb growouts loved them! They even beat all of the green neon/cardinal tetras to getting the larvae, which is even more reassuring to me that they'll grow up to become healthy individuals.

If you're still having troubles with those Odessas, I remember hearing Greg Sage talking about how he keeps and breeds them prolifically
