  1. What sounds like the start of a really impressive build. Can't wait to see it all come together. Thanks for sharing. Super interesting read. Couple of things stand out to me... firstly be very careful on the web of return pipes buried under the sand. Personally I think the risk of serious issue outways any margianl benefits... but if you can pull it off, it will be extremely interesting. Any sand in the tank is (according to brstv) like a "kitty litter tray". So sand will need spot cleaning unless your web is extensive. My worry is multifold, firstly any sand agitation (movement of sand in
  2. We all start somewhere, and it doesn't matter if your tank is a bucket, a circular bowl, an old bottle or a 9ft crystal clear glass aquarium, the act of keeping a marine environment in a contained space is possibly one of the most challenging hobbies you can select. But it isn't that complicated, and more and more people are seeing success. So, whether it is a small bowl (not recommended) or something more spectacular there are some common things you need to consider. 1). WATER QUALITY. Reef keeping (salt water in our case as this forum is for us salties so sadly no goldfish allowed... but
  3. Forgotten Heros Part 2: Diatom Filters Imagine if you will a filter that is so fine it can polish your saltwater removing even bacteria. That, my fellow reefers is a diatomaceous earth (aka Diatom) filter. Now, the funny thing about a diatom filter is that, well, it isn't a filter per se. [Huh??] It is actually a natural powder made form fossilised algea (diatoms). The powder is added to a filter to reduce the size of the pores of that filter and is equivalent of adding millions of microscopic 'bio balls'. These microscopic particles (which are actually fossilised diatom shells) contain
  4. An RO membrane is considered the most important element of an RODI system. The sediment and carbon filters act as pre filters to reduce the amount of large moleculed contaminants entering and clogging the membrane. It is the membrane that does all the heavy lifting. Why the RO is so important is unlike the carbon blocks it works under pressure (hence good systems include a pump) and as such it literally strains virtually all unwanted impurities from the mains supply, allowing only 'pure' water molecules to pass through... so as long as you are happy having small molecule impurities, salts, hea
  5. There is much you could try, from simply reordering you pre stage, through to removing the last RO membrane. However in the longterm I certainly would consider moving to the 5--> carbon-->carbon inital stage setup simply because it is tried and tested. I suspect it is the RO membrane. I had a similar spike once, with a double RO set up just like yours and it turned out my RO membranes were depleted. Because I only had one spare, I moved to a single new RO membrane and instantly got 0TDS. Drinking water system... hmmm. I doubt would be an issues as the hardware typically is the same (1
  6. You said 'RO' does that mean you dont have DI resin?? I get 0 TDS all the time from a simple 5 micron sediment filter, two carbon blocks, a basic 75gpd RO membrane and some mixed bed DI resin. I tend to work backwards when I have an RODI issue (The sediment and carbon filter tend to help the RO membrane last longer. The membrane does all the heavy lifting, hence the reason to work backwards). So, firstly check your DI resin is fully packed well into the DI canister, as you could be reading some creep if not. If all packed in, does it need replacing?? If not and the resin is ok, next bet is y
  7. Extending the call for help. If anyone has an Eden 135 front cover plate with tubes (as per photo) can you contact me to deal. Also looking for a spare impeller to fit the same pump. Thanks. Sent from Singapore Reef Club mobile app
  8. Hopefully you find one. Else you may want to check out the 'Kamoer one' as is a cheap, reliable, branded ATO. Just $65 new from madpetz. Sent from Singapore Reef Club mobile app
  9. I need some help rebuilding an old skimz e series CM202 Calcium Reactor. So if you have any spare parts available let me know. I am especially interested if you have either a LID, Degassing chamber (from any skimz model), bubble counter (again from any skimz model). WhatsApp me on 8808zero763 or PM me. Thanks!

  10. How big is the sump going to be? Sent from Singapore Reef Club mobile app
  11. Suggest you think about each section, and take a look at what is in the market from the likes of Geosreef and depending on budget Royal Exclusive just for ideas. Reefnerd on youtube just had a custom acrylic sump made for his tank which is worth looking at. Obviously budget comes into question when you want all the bells and whistles but at least it will give you an idea. I got the acrylic locally but did all the construction myself.

  12. The question is what do you need out of your sump? If you are looking for the sump to perform specific activities and those activities go beyond a simple set of chambers, then I would go with acrylic. I have owned both glass and acrylic, I have also custom made both. In my experience Acrylic allows you to be way more creative. For example, you can have built in roller filters, built in reactors, adjustable baffles, lids, etc etc. This means the sump becomes more functional. Regarding production acrylic. Clearly you are getting high production quality, but you can have a sump custom made

  14. Washed, but never used. WhatsApp me on 88080763 or PM me here. Happy reefing. Sent from Singapore Reef Club mobile app
  15. I second that hahaha. Have you ever thought of doing a live stream q&a ? Sent from Singapore Reef Club mobile app
  16. For $20, I have a sturdy 28L, 6mm glass, ATO reservoir (dimensions in cm 58 x 12 x48high). It has split glass cover/lids which have been drilled for cables and tubes. Could also used as a small refugium or if adventurous a mini display tank. Just $20. WhatsApp me on 88080763 or PM me here. Happy reefing. Sent from Singapore Reef Club mobile app

  18. I have preloved a reeflink available for just $25. (Also comes with orignal box and a custom bracket). If interested let me know on 88080763. Sent from Singapore Reef Club mobile app
  19. AI prime. Invariably as your tank size increases over time you will save money buys something like an AI prime as it can be used in conjunction with more pucks on larger systems. Plus has better resale value. Sent from Singapore Reef Club mobile app
  20. One thing I love about this hobby is the constant ability to learn something new. However, there are also occasions where it is worth learning something old. Techniques that reefers used historically but are in dire need of resurrection, forgotten heroes (or heroines) so to speak. As such I wanted to share a few topics on reefing that I hope you find useful. So let's start the ball rolling with the first forgotten hero... Sulphur Denitrifiers. For the life of me I just don't understand why Sulphur Reactors are not more popular after all they are possibly one of the easiest "set and
  21. Return pumps: For the return pump just make sure that you get one with enough head pressure to not only pump sufficiently through to your chiller, but also up to the tank, and to service any manifold (from which you can plumb a reactor to it) I would suggest an ecotech S2. If cost is an issue then get a smaller pump like nyos viper 3.0. Your light will do nicely. Just raise it up higher off the waters surface (12 inches or more). Your light will give you a more blanket light effect which will avoid shadows.. so is actually beneficial. However, such a large light may (will) produce some 'l
  22. This is a really interesting result, as in the wild coral reefs record some of the highest levels of DO (upto 200% 15+ ml) because of a combination of photosynthesis and increased aeration from eddies and breaking waves. What you are suggesting is that aeration via a skimmer actually lowers the DO. Whilst I have observed between fluctuations between 100% and 150% on my own tank I have never seen a case where a skimmer reduces DO. But what I love about this hobby is the opportunity to learn something new. Will PM you... Sent from Singapore Reef Club mobile app
  23. No worries. I just pm'd you. Sent from Singapore Reef Club mobile app
  24. As long as your tank doesn't have tempered glass then yep drilling is best way. If you are stuck, happy to help you. I can come drill your tank for you. I have drilled a few tanks before. It isn't as scary as you may think. Sent from Singapore Reef Club mobile app
