Just started using a BRS 150gpd water saver unit. Pressure seems to run about 40-50. I ran it for 1 hour as they recommend when first starting it up. Discarded all water.
Then ran the system and it produced 40 gallons in about 7 hours. Fills up a 5 gallon bucket (I'm using a plastic water storage container, made to look like a water barrel, which has a flattened one side, meant to hold 40 gallons, with a float valve installed in it) within 45-50 minutes. Within 1 hour can have a 6 gallon bucket heated to tank temp 78F and saltwater and 5 gallons ready within 1 hour after that. So fairly quick. TDS going into the final membrane was about 3-4 initially.
With TDS out reading 0. However I noted that the water in the collections is running TDS 2-3-4, I don't know if this is good or bad. I assume this is fine and it is usable.
Now seems to run 12-14 coming into the last canister and 1 coming out of the last canister (final product) according to the in-line TDS meter.
Question # 1: Do you have to produce "O" TDS for it to be used?
Question # 2: Can RODI water of 1-5 be used?
Question # 3: What would be the upper limit usable?
The pH however has me stumped. The pH seems to run about 8.32-8.4 for the final product. Would of thought it would have to be lower at 7.0 or just under with RODI. My tap water is well water with a TDS around 125-135. Waste water is about 200 TDS.
I'm planning to use the waste for my freshwater tanks.
Question # 4: Can you actually have a high pH for RODI water? What causes that and how to reduce it. I understand you can buffer up, but if it stays where it is 8.32-8.40 on the RODI, I don't have to do anything. But what do I do if it is over pH > 8.4?
The BRS 150gpd water saver unit is fairly easy to set up and works well with the auto shut off as well as the float valve. The price for this 5 chamber (really it is 6 chambers) unit is better than others that I have seen. The unit is supposed to reduce the waste from about a 1 : 4 ratio of final product : waste water to about 1 : 2.
I still have to time that out and see what happens with volumes wasted and volumes produced, how fast, how much and measure and time it all out.
Too bad there is not an optional floor rack it can be mounted on. Also flow diverter doesn't come with a garden hose to faucet connector, which is what is in most slop and laundry room sinks. Took me a week to locate connectors that were needed - I have two. The connectors the unit comes with are not labeled regarding the thread size and numbers.
I have a 30 Gallon JBJ rimless, now up and running 104 days, with fish, cleanup crew and a lot of coral in this tank.
I am running high Nitrates, but Phosphates fine at 0.25 and all other parameters are fine and stable.
Now with an RODI and preparing saltwater so quickly, I can do weekly or more often water changes if needed.
I also recently just purchased a Fluval 5 gallon EVO tank, to use as a holding, quarantine tank and for some corals and growing of frags.
Can anyone help me on these questions and provide any additional advice?
Question # 5: Where do you go to start a new thread?
I'm doing this in Conversations and I am not sure that is correct. I don't see a place to "start a new thread".
