Okay, so the rack is moving along slowly, very slowly. I seem to either never get the right parts or just completely misjudge something. In all things a software developer works on we over complicate it.
Well here is the progress I have made. This is a post on the filtration I setup, I created a 7 stage filtration system. Originally, it was only 6 stage and then it became clear to me that I need to add an RO unit to hit the numbers I wanted.
Stages:
- Sediment Filter (1 micron nominal) (block)
- Sediment Filter (1 micron absolute) (pleated)
- Carbon Block Filter (ground seashell)
- OBE Ceramic Filter (0.9 micron absolute)
- Sediment Filter (0.2 micron absolute)
- 2x RO membrane in parallel (total 300g/day)
- Resin (MBD-30 Nuclear Grade Mixed Bed DI Resin)
I originally did not have stage 6 (2x RO Membrane), the reason I added that in was because I was trying to filter my water down to a certain point and I was unable to get it there. So my solution was to filter it down to 0ppm and then add minerals back into the water.
My city has awful water and they report wrong numbers to the residents. I did not realize it until I start looking into everything for this project. The city promotes that we have good quality water, from my testing we are close to 600ppm strait from the tap and 8+ ph. I figured out that is why I was losing those dime sized babies and some of the new fish were having health problems. Even doing large water changes daily did nothing for these fish.
It was night and day between giving these fish better water quality. With minerals added back in I come out to around 75ppm and about 6ph. With these levels I have fish laying eggs now. Quick side note I keep the rack at about 75-120ppm, the new water being added to the rack is ~75ppm.
You may be asking what minerals is he adding back in, well I dug through old posts on
simplydiscus forum and found some mixes that people recommended. Here is the one I am using and the fish seem to really like.
Once you have it mixed you can now add the following amounts to get the desired results.
For Mixture RO Water TDS
Breeding 1/2 tsp 50 gal ~40 ppm
Fry 1 tsp 50 gal ~80 ppm
Growout/Adult 1-1/2 tsp 50 gal ~120 ppm
I have been keeping my tanks in the Fry to Growout/Adult range.
Here are images of what I have been talking about
So my process is to have staging water always ready I run it through all these filters and then store it in an extra 55 gallon tank I have. In the 55 gallon I aerate, heat, and remineralize the water, then I can use it to do my water change. Once I have the full rack up and running I will be using a 275 gallon IBC tote to stage my water in. This 55 gallon is just a temporary setup.
I added pressure gauges throughout my filtration setup to keep an eye on how well my filters are holding up.
