From the start... 155g Bowfront RBP tank

  • We are currently upgrading MFK. thanks! -neo
cariba and Reds can be mixed, Just try and get them at the same size and add them all to your new tank at the same time. If I had more room Id have them mixed with my reds.
 
Well here is the current stock that is crammed in the 55g...

The three larger RBPs.

After adding four undersized (more than 2" difference in size) RBP to the 55g I realized that I had gambled and lost. The smaller ones were being devoured at night so I put up a ¼” acrylic divider to protect the other two.

Two of the four newer fish were wild caught, but I have no idea which ones survived that first week.

In any case, I would love to introduce a few cariba piranha but it will be tricky because I already have significant size differences that I'm trying to deal with. The smaller RBP are growing rapidly-- we all know they grow about 1" a month up to about 6" so.

If the cariba are introduced later, would I be able to reduce infighting over territory by significantly shifting the aquascape? I have dozens of artificial plants and rocks/ wood etc. that I've used in the past to make those kinds of adjustments.

PeAcE!

I think if you put them all in the new tank at teh same size you prob be ok, Id try and get the new fish at least in the 3 to 4 " range.
 
you can use the 55g as grow out and power feed them to increase, as long as the size difference is within 1-2" you should be fine. feed the bigger reds first, do a water change with cooler water and rearrange decor then add new fish when you are ready, that will increase the chance of success. or don't have to rearrange decor, what i do is after water change, chase them with a net or something to freak them out then add new fish then chase them all together. once they settle down they will be buddies.i have done this way many times with good result but note that it maybe be the same for you, each setup is different. you can lower the temp to reduce aggression too when you first introduce them.

Your RBP tank story was great. I read most of that long thread. Awesome pics.



I agree that even at 4:1 ratio of waste to produce is too much to send down the drain. Do you test for TDS with this configuration? According to the research you would have to replace the filters more often because of the increase of dissolved material in the water once it was waste.

I like the idea of rerouting the waste back into the hot line of the house. I was wondering if anyone has had success using a retro-fit zero-waste kit like the ones Watt sells. https://www.wattspremier.com/products.php?product=Zero-Waste-Retrofit-Kit

Without a holding tank to open the switch the pump would run continuously. This could affect the longevity of the pump, but I'm not that concerned about the cost. The model there only uses 14 Watts of power. I could easily find a lightbulb to unscrew to cover the cost of running it, and I will certainly be helping the environment.

Any ideas about retrofit kits?

Thanks alot glad you like it. i have a TDS unit on my filter just went to check for you and the batteries are dead so once i get some more i'll do a reading for you.

you bought them at adult size? even online ones that size are pretty expensive

The largest one was a "rescue" from a family friend. All of the other six (including the two that perished) were purchased for between $20-30 at sizes ranging from 2.5" to 3.5" I highly recommend AE Aquatics. They ship to 26 states. Cool guys and very healthy stock. They give you the fish in a bag with pure oxygen up top and a live-arrival guarantee. They are in Bayonne NJ so I just drive there.


As for the zero-waste configuration, I calculate that running the RO/DI filter would cost about 55 cents a day in wasted water--under the best operating conditions, more as the filters wore out. The environmental impact is hard for me to stomach too. The zero-waste pump would pay for itself over the course of 14 months if I was running the system continuously. It would take longer if I was only producing RO water for four hours a day-- a length of time which would replenish the water more than 35% during the course of a week. At that rate I'd have to expect the pump to last over five years to recoup the cost of lost waste water. Then again, saving water is about more than saving money to me.

I'm going to see if I can incorporate a time-operated solenoid valve to automatically run the system during the night for water changes. When I figure out the final setup for the plumbing I'll make a diagram to explain it all.

It seems that according to the literature a RO membrane will lose about a third of it's lifespan if the discharge/waste water is allowed to re-enter the system. The unit will produce clean water, but won't last as long. A third of the life ends up costing about $80 a year in extra replacement costs for the Kent System I have purchased. I would be able to recoup that difference in just under two years with the zero-waste pump. Any additional life I got out of the pump would only add to the overall savings.

Cheap -- let the water run down the drain
Inexpensive -- hope the zero-waste pump lasts a long time
More expensive -- run the waste water back through the RO membrane

Hope my research helps.

I bought an RBP from alex at aeaquatics as well, nice guy. Those Piranha look quite large tho, 7-8+ inches. how long have you had them? thought this was a recent setup

Yea the guys at AE are great. I go there from time to time sometimes just go there to hangout if they happen to be in the store, lol
Just curious, where in NJ are you?
