  8. Hi all, I'm decommission-ing my tank of 3.5 years to migrate. Used to power up a 400G reef tank. As you can see, the equipments are overkilled as i used multiples as backup and contingencies. All items are of perfect running condition, well mantained. Aside from what's mentioned, equipment usage has been for 3.5 years Return pumps Reef octopus HY10,000. 9 months old (newly changed) - SGD 200 / RM 630 Reef octopus HY7,000. 9 months old (newly changed) - SGD 150/ Rm 465 Reef octopus HY7,000. 3.5 years old (9 months old impeller) - SGD 100/ RM 315 Lights Orphek Atlantik version
  9. Understanding how RO membranes work, unlike per filters, they do not exhaust.... Rather, they get damaged. Basically, at the RO membrane, filtration due to osmotic pressure rather then the hydrostatic pressure comes into play in contrast to hydrostatic pressures at the prefilters resulting it in requiring frequent changing and getting exhausted. In a nutshell, Impurities get trapped in prefilters, but not in membranes.... It's not suppose to.... At the membrane stage, pure water seeps through the membrane via osmotic pressure leaving behind water with highe concentration of dissolved impuriti
  10. Hi all, Need some help... I'm currently using an RO/DI from madpetz rated at 400gpd which comes with 2x200gpd membranes. I've been using this filter since the past 8 months. Plus minus, I use about 600G per month. Over the past 2-3 weeks, I have been noticing diatom blooms despite PO4 and Nitrates at desired levels. It could possibly be overfeeding too.... But, was wondering, how long does an RO/DI membrane last? When do I know when to change it? Or should I change it on a yearly basis? What about the DI resins? Do we need to top it up or replace it at regular intervals? I guess
  11. I've been using reef crystal from day 1 of my current setup for the simple reasons of it being cheaper. However, for the duration of using the 6 tubs, I find it really difficult to get my Mg levels up.... They were constantly dwelling at 1200+. I had to dose 250-300g MgCl each time I do a water change. There after, I changed to red sea coral pro, I have good parameters and good coralline algae growth which I didn't have over the past 6 months I was using reef crystal. Now, my concerns are that I find significant difference between the dissolution rate. Reef crystal dissolves completely withi
