Ok, Been away from home for nearly three weeks (will be three weeks by the time we get home tomorrow night.) The outdoor system is set up with automatic feeders and battery backup air and the neighbor has been checking on it.

This indoor system doesn't have any extra backups though there is air as well as the pump running on a timer 15 min on 15 min off.

Anyway, there were 18 of those unplanned tilapia babies in the small aquarium. I don't have a feeder to do meal for the aquarium. I put a bunch of rocks with lots of algae growing on them into the aquarium for them to graze on and had also left a couple lettuce plants propped in the corner of the aquarium for them to eat off of. I had fed them pretty heavily before leaving but turned down then turned off the heater so they are likely in 75 F water.

Any bets on how many baby tilapia I will have when we get home?
Will it be none and a wet floor due to some accident with the system? Or Will it be all 18 to our amazement or what do people think?

The answer Tomorrow night (or the next morning if I'm spending the night cleaning up a mess when we get home.)

And the results.

3 but not all where I expected them.

1 still in the small aquarium where the 18 started.

1 over in the big aquarium

And 1 down in the sump.

The only way from the small aquarium to the sump would be through the no holes over flow and accross a bit of gravel to get down into the loop siphon into the sump. Only way from the sump up to the big aquarium is a ride through the pump. The three are still alive.

Go figure.

So I have the tree babies left from the 18 I had brought into the aquarium before going on vacation. I found one stray that had survived in the main system that I've since brought into the aquarium.

We had a leak issue one night not long ago, I could not find a leak so my best guess is that the no holes overflow from the small aquarium developed a bubble and failed, causing some water loss onto the floor some how. Currently all 4 babies are over in the big aquarium. They are still smaller than my little finger nail.

Well the 4 surviving babies are now about an inch long and can't swim through the cage mesh anymore. I've built them a small cage and put it in the end of the big system so they can enjoy the warmer water outside and leave the small aquarium available for new babies if I manage to get any of the breeders to do their thing.
Here are some pictures of the no holes overflows that I've adapted to be venturi drain no holes overflows. They seem to be working really well for keeping the gunk out of the bottoms of the aquarium now.

Since it is possible for a no holes over flow to get a bubble and stop working, I have two of them in the small aquarium and the large Aquarium has a regular standpipe venturi drain through the hole in the bottom of the tank and a backup no holes overflow at the end of the tank by the bucket grow beds.

I have also made a hat for the aquarium system since the cook had to rescue the male breeder from the floor the other night. It seems it was pure chance he went in there and noticed the fish on the floor in time to save him.

I'm not sure if I mentioned my heater sump idea for this system so I'll explain it again here.
The indoor aquarium system isn't really warm enough on it's own at our indoor air temps to make a good tilapia breeding system. I don't want to spend lots of money running aquarium heaters. It is hot outside this time of year, this system uses a sump, there is a handy window of an appropriate height, just needed another blue barrel.

What I figured was during the hot summer months, simply using an outdoor sump would bring up the water temperatures at least over 80 in the system. I've found that the temp gets over 80 F during the day but will fall back to about 78 F many nights. That is better than the tank temps of 73-78 F I'd been having before.

I simply cut a side hole in a blue barrel and shoved it down between the house wall and the shrubs. Shrubs are holding it in place quite nicely, new they had to be good for something. Then I re-configured the plumbing to go through the window. I braced the window open with a board blocking all but the area where the pipes and power cord go through. Stuffed steel wool in around the pipes, insulated behind the steel wool. Put a flap of pond liner on the outside to keep driving rain from seeping in through the board. Put some weather stripping between the two window parts to keep bugs out. secured a board to keep window from being opened from the outside.

The pump is now outside in the blue barrel and the drains go out to the blue barrel. I've moved the silly little solar powered bubblers to this sump location, they only run when the sun hits them but I figured pumping the warmer air in to the sun warmed sump would be better than running an air tube from inside.

I actually have the plumbing run such that I can switch back to the indoor sump pretty easily when the really cool weather hits.

I think if I were to build a little "cold frame" over the barrel and paint the outside of the barrel black, I would probably get much more heating out of it and perhaps not even need to switch back to the indoor sump. Tricky part is, the shrubs are kinda in the way for that.

Really like your idea of doing a small indoor unit. Can learn a lot about the fish this way. Nice set up.

How are you removing air bubbles from the overflow pipe? Those things actually make me nervous, especially bringing them indoors.

I have posted my much acclaimed :cheers: duckbill valve solution for that on the "no holes overflows" thread:

I know you know about it and have adopted it :P

I too am intrigued by these Mardel testers, TCL

A search on the Internet gave only as result scores of distributors, none of them in Belgium
nothing about the manufacturer

you wouldn't happen to have your users' manual at hand?

surely there must be some info on the manufacturing company

address, phone number, maybe website...
I think it would be good to start somewhere a thread where manufacturers interesting to AP are listed
gives us a way to get to roots

and roots are important to AP, aren't they?

I've since pulled those mardel testers out. They are essentially continuous test strips. Most of us don't trust test strips anymore. The pH one never really read correctly.
the Ammonia one did give me good warning when things were getting bad early on but they need to be replaced every 6 weeks or so.
Lets see if I can find you a link to the place I ordered them from. Happens to be the same place I get my other testing stuff. I believe there is another company that also makes continuous testing indicators that are somewhat similar but I think they may be able to get re-fills for theirs.
http://www.thatpetplace.com/pet/group/11390/product.web
So here is where I got mine. They do carry at lest one other of the continuous things. You can see if they will share the info from the manufacturer with you but I'm not impressed with them anymore so I'm not that interested.
