Question about a Constant Water Exchange System

[Danger_Chicken]

There are some folks on here that remove chloramines with this filter:

I use the filterguys. the only issue is ammonia is the by-product. Not really an issue if you have live plants or a strong bio filter.

Neoprodigy has a drip system on a water supply that has chloramines and doses prime automatically. If you are going to go as far as dripping RO Right, then how about just skipping the RO and dripping prime. Much less maintenance and parts to break.

Unless your fish are wild caught I wouldn't worry too much about water param's in the wild. You and them are much better off if they are acclimated to your water supply. That being said I've never owned RBP so you might want to ask in the pirranha section about how sensetive they are to water params.

One 300w heaters on a 150g should be pleanty.

I liked his approach; it is well thought out.

There are a few reasons I would stay with the RO/DI unit for now. Number one, the thing is bought and set up and paid for, haha. Seriously though, I also use it to create drinking/ cooking water. I live on Long Island and I know we get all sorts of nasty stuff in the water. I guess I feel safest using the purified water and then reconstituting it. My challenge now is to find a cost effective drip solution for the RO Right and a timer/ solenoid that can be programmed so the whole system gets some down time. Several members have suggested various valves that may work, but I haven't been to the store this week to check out irrigation supplies.

RBP are well known to be hardy fish that tolerate a fairly wide range of conditions. For example, pH can range from 5.5 all the way up to 8.2 in some cases. Amazing. However, I've been trying to find scientific data so I could create some kind of baseline from which to start. If I know roughly what nature intended for the fish as it evolved, I might provide for them better at home. So yeah, it's a starting point, something to aim for as I go forward.
