Zetlight LED and red sea foundation pending collection later..

Day 36 Some new toys arrived today! First up, the JEBO 9W UV system, hooked up to my return manifold and adjusted to a return flow rate of about 150-200l/hr which is about 1 turnover rate per hour for my system. So hopefully this is able to hit the recommanded 90,000 micro watts/cm2 exposure needed to eliminate protozoa. By the next morning, the water clarity looks significantly better! The UV was actually installed to help manage pest like ich and velvet, although there's no way this will erdicate those pest completely. A plus side is that it also helps in improving water clarity. Next up is the Jebao 3.4 wifi doser, the last time i used jebao dosers were a couple years back and they were very reliable in my opinion. Its great to see they have a wifi version now and im actually very surprised by its built quality! Its no longer the black and cheap plastic and weighs like its almost empty inside. Its made up of thicker soft touch plastic and is actually pretty heavy for its size. Also got my hands on an interesting algae scrubber. Its design is simple and built quality is very decent. There is a 600l/hr pump at the bottom which sends water up and cascades down the sides, while plastic baffles silent any noise produced by the cascading water. There's also a 15w led with 4 red 1 blue led. It takes up very little space (13x31cm footprint) and even came with some algae to kick start the scrubber. I have set the led on timer to turn on every 7 hours with a 1 hour rest interval, So with everything hooked up, cabinet looking real messy, but im glad i still have some space left in the sump should i ever need more equipments. Some zoas that i've gotten for about a week are doing great! Acans too Currently battling diatoms, also was unlucky when i added my a naoko wrasse and it came with velvet, died within a few days along with my copperband butterfly. The tank will now go fallow for 6 weeks until mid august before i can get another fish. Thanks for viewing!

1) Innovative Marine Mini-Max Full size reactor. This is the biggest of all 3 mini-max with a capacity of 1L meant for sump usage. Dropped the inside portion of the reactor and had to glue the broken acrylic back. Does not affect the performance of the reactor because that portion that broke serve no purpose. cable has been extended before but does not affect performance of the pump. Specs and price reference: https://www.bulkreefsupply.com/minimax-fullsize-all-in-one-media-reactor-innovative-marine.html Selling cheap at only $50 due to the above causes, also will throw in a tub of 1L Rowaphos (70% left and media had turned red) free. 2) Brand new Zetlight Mini 3x1w White LED light. Great for lighting up the sump or a mini refugium. got it as a gift but no use for me.

amazing coloration!

I'll take a video when i do my regular WC, i can fill up a 5L tub in 5 mins and probably can go faster while still producing 0 tds. 1 drip per second sounds really bad! Got to check if your home TDS is very high or if your resin has exhausted.

Maybe more tank information would help, like tank size etc etc.. A sure way to reduce nitrate is by doing water change, or you can start carbon dosing with Vinegar, or commercially available products like Red Sea NoPox.

The end result is the same, 0 TDS pure distilled water. Yes using DI alone without RO depletes the DI faster BUT with our TDS at 60+ tds it lasts much longer than you might expect. Still, a RODI unit will last longer than a DI only unit. But is the trade-off of waste water and high cost (booster pump is almost a must) worth it? i personally think it is not. Infact, i know some reefers who use a single 20" huge DI canister and pack it full with DI resin and they last a very long time before you see TDS creeping up above 0. My personal usage wise, the 5 stage DI unit i have can last 6 months with a weekly 10% WC of my 170L tank, a 5L DI resin pack cost about $45 and the whole pack would last me about 15 months, the Carbon block is pretty cheap and can be bought locally below $10. That is a very low cost to maintain, and remains relatively low even if i double my tank size volume and do the same 10% WC weekly. Most people buy RODI because that is what most shops sell and that is what they are told they need, to achieve RODI water. These are of course my own opinion and both option definitely works at producing 0 TDS water which ultimately is what we are looking for.

what u said makes sense and should be the reason why you're not getting 0 tds. i have used the Crystal pro a long time ago but don't remember having issue with it. Maybe you would want to remove and reassemble your unit? With a tap water TDS of 60+, there is no reason why you need RO, yes RO membrane can last a long time but you have to deal with waste water and a slow flow rate and if you stay in high floor you'll definitely need a booster pump. The trade-off is not significant enough because DI alone can reduce the TDS to 0 and still last a long time. This is my DIY 5 stage DI unit with all the parts sourced from taobao except for the resin.

What is your tap water TDS? Singapore's tap water are generally very soft with pretty low TDS (below 100) therefore RO is not a must (or infact not necessary at all). I personally use a 5 Stage DI system with 1 stage carbon and 4 stage DI water and produces 0 TDS even with fast flow rate, my tap water is 60-70 TDS. It sounds to me you that your resin have either expired or exhausted that's why its producing high TDS water.

Time to upgrade bro!

Really nice gesture bro! kudos to u!

Thanks! I borrowed it from a fellow reefer.

i meant to say Curve 7 not 5!

Yeah 2 pump option is definitely more fail-proof, i used to run a DCP12000 on my 4ft 450L system and i barely go over 70% power and they are near silent even after 3 years of usage. I believe at max capacity you might only hear a soft humming noise.

Your return option looks good, though i personally would go for the DCP12000 and run it at a lower speed which i personally believes lengthens the lifespan of the pump, its also quieter this way. As for your skimmer, i'm currently using the BM Z7 on my 160L tank and it seems to be abit too overkill for now (new set up, not skimming much), but i would suggest you go for the Curve 5 or Z7/Z8 at least.

Day 22 Got my hands on a Biotek Marine BTM-3000 PAR sensor! The Noopsyche looks bright to me but i guess a PAR reading on the tank would be very beneficial when deciding on coral placement. The light is currently 8" above the water level, and positioned slight over half the width of the tank in order to 'blast'' the rock scape and first half of the tank. So for testing purposes, i set all 5 channels (White, Red/Green, Blue, Royal Blue and UV) to 100%. The single Kessil-like lens on each led puck seems to have diffused the lights pretty well, and im surprised a single unit at 100w over a 60x50x50m tank can produce over 200 par on even the front corner of the sandbed. But as expected from a typical spotlight LED fixture, the PAR is really low on the middle and top sides of the tank. Next i tested a more realistic setting of White & Red/Green at 50%, and Blue, Royal Blue and UV at 100%. The tank looks abit blue for the camera so i did some white balance editing. Expectedly the Noopsyche still performed pretty well and well within the BRS recommandation of 250-350 PAR for SPS. I think raising the light to 10" above water level (the max height for the stand) might improve the spread and i will provide an update again! Thanks for viewing!

Thanks everyone!!!!

All sold. Thanks
