Videos like this is why i see this channel as the Worlds number one aquarium channel. Thank you so much far putting in the time and effort to create these videos.
I've been in the saltwater aquarium hobby for almost 8 years now (off and on) and I've just now discovered you guys. So glad that we've got people like you taking the time to use data to make conclusive determinations rather than the typical spineless banter I see. It's very needed, thank you for your exceptional videos and the hard work you're putting in to them.
I love this RO/DI series. I bought a BRS dual DI add on kit when I say the first video on it. Very happy with it. Might switch to the 3 stage system when the series concludes, depending on results.
I am so happy that you guys publish these videos! Proving or disproving convention is a public service like no other. If you sell the item I want, I will continue to buy it from you. That is probably the best thanks I can offer. Luckily, your prices are great too so it is a no brainer. Thanks again.
perfect timing. My new 1 month old tank just developed a ditom bloom out of nowhere and i was very confused why. My DI media is about 80% done. I will change it now. Im sure this is whats happened.
Another great video! I knew ion displacement could happen; I was just surprised that it happened so soon, before the resin is actually 'depleted.' The issue I've noticed is that my TDS reads 0 for quite some time after my resin appears to be depleted based on color change. I've been thinking about getting a second canister, this basically confirms that I need to do it.
Great info! I always had a feeling that my rodi was letting silicate pass through. This kind of solidified my thoughts. Thanks as always for another great video!
Ok im scared now considering I don’t look at the tds meter everytime i make rodi water.. How often should I be changing the filter? I make 5-10 gallon rodi water every week and i have 4 stage brs rodi unit.. thanks for the excellent video 😊
How does "meg ohm-cm resistivity" factor into DI resin? What does it mean? Apparently this has to do with the purity of the water coming from the DI resin and I only see it mentioned by a select few manufacturers.
Hello BRS! I have a 90 gallon tank that has been overrun by derbesia turf algae that came in on a frag plug. I have watched your algae video and could not tackle the issue. Would yall happen to know any natural predators or secrets for this algae? Thank you and this DI video was helpful
I've always run 2 DI canisters for my level of laziness, who knew it also had the benefit of stopping silica and ammonia from leaching out. Next design will be quadruple DI resin, cation only, anion only, and 2 mixed beds again for a level of laziness. Just hope you don't run out of the resins like you did the last time you did a resin video!
Question.. my d.i. resin is depleted and I am not able to buy more right now. I need to make water for water changes. Should I just use the r.o. and not the d.i. since the d.i. is depleted?
Jase Poag You could always fill 2 cartidges with anion resin and the 3rd with mixed bed. If you're not going through much cation, then a mixed bed should suffice on the end.
So obviously the "buster resin" comment was geared towards the Spectrapure Silicabuster. I'm curious to know why you think the Spectrapure Silicabuster DI resin is a gimmick? Did you guys perform any testing to make that claim? The Silicabuster DI cartidge is 3/4 of regular blue, color changing mixed bed resin and the bottom 1/4 is the brown silica resin. In your demonstration the silica will keep getting bounced by another ion. So if the bottom quarter of the cartridge is only for Silica absorption, other ions would bypass it. And if the silica resin gets full, it can still go to the mixed bed resin above it. The high capacity Silicabuster lasts me 3 times longer than the regular resin. It costs more, but I'm saving in the amount a resin I have to change (plus I like pre-filled cartridges). Spectrapure is one of the best in water purification. I would LOVE to see a Silicabuster catridge vs the bulk blue resin to see the results.
Question?? So, how long typical would DI resins last. During this video it seem that they only ran the unit for 8 hours before it was exhausted. Seems very short time. my unit would only produce 150lt in this time?
These tests were conducted with straight tap water feeding the DI canisters, rather than being pre-filtered by the sediment, carbon block, and RO membrane. This is why the resin exhausted so quickly, whereas in a full RODI system you would see much greater DI resin life.
I would love to see a BRS investigates on flow. There are some reefers that swear the more flow the better and that you can't have too much. I.E. I have a friend that suggests, no insists, that 100X turnover in flow absolutely the best way and claims he's had better growth since he started doing it... I don't see a difference :-P. Others say that they have better growth with not as much... Obviously corals need flow, SPS needs a lot, but surely there is a 'Happy Zone' where increasing the flow starts to inhibit growth vs helping. Does a 100X turnover actually enhance coral growth or slow it down? Or would 50X turnover be better? Or is there never to much!?!
So silica and ammonia get through, is this even a problem considering the bacteria in an established tank will consume the ammonia and the algae in a refugium will consume the silica? I only use RODI for top off because I don’t do water changes so any addition of ammonia or silica would be very gradual and I would think my tank could more than keep up with it in terms of processing these elements. Am I way off base with this assumption?
I ask a question on a video you guys made half a year ago and you guys are still nice enough to respond. You guys are AMAZING! I’ve been a customer for years and appreciate all that you do for the community and the pursuit of truth.
I always change my DI the minute it reads .01 Now I guess I need to add a 2 stage so I can do the triple threat DI attack!! If my Water pressure is right at 60PSI with one DI will I need to add a booster to maintain that PSI??
I wish there was a way to stop wasting so much water. What I mean is the water waste after the membranes if we could find a way to recycle it back through water is really expensive where I live
My water always tastes sketchy yet my resin hasnt gone even remotely orange and my tds doesnt even go above 1 by the 3rd stage...guess i didn’t really need 6 stages in the first place
BulkReefSupplyCom I have a predator system with a shark so the bioload is heavy. I am talking 40-100 nitrates. Normally stays in the 40-50 range but hits 80-100 sometimes. I am wondering if the powder blue tang can handle it. Since this isn’t a reef any other ways to lower nitrate other than a fuge and skimmer?
