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 2.2 with controller (5 units) - Priced at SDG350/RM1085 1 unit , SGD650/Rm2010 for 2 units, SGD 950/Rm2945 for 3 units, SGD 1200/Rm3720 for 4 units and SGD 1350/Rm4185 for 5 units *each unit good for 3 x 2 feet tank. 3 units will be able to cover 7 ft tank!

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 impurities which gets wasted. Now, my question is... How will I know if it is damaged? From what I read, TDS is not an indicator for a membrane change.... As for the resins, do you add or do you replace and throw away the remaining in the cartridge? Many thanks

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, I have been neglecting the filtration part of my system. Please advice and help... On another note, can anyone help suggest where to get affordable replacement prefilters, membranes and resins so I can do more regular changes. Many thanks in advanced

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 within an hour of mixing and is good to go. On the other hand, coral pro seems to be still cloudy 2 hours after mixing and the cloudiness continues for the next couple of hours after water change in contrary to reef crystal. I will probably give DD a try next. P/s : I don't really trust the tables which tabulate the different parameters of different salt. I've tested all the salts I used and they differ greatly from batch to batch. I've gotten Mg as low as 1100 and have not exceeded 1240 throughout the different tubs of reef crystal salt. And for the skeptics, I send my fresh mix sample to the medical lab to test for Mg when I persistently had Mg problems... Just need to test the accuracy of salifert test kit, which I must say, is pretty accurate

So sorry for the late reply.... Of course I remember u la.... Thought u went to china for good already... How many wife's u brought back? I'll be in sg this coming weekend... U say say only.... Still no sight
