Its no rush. I just what to take the time to do it right. Thanks.here is a sb rinse thread, sorry so long lol but at least has examples of others tanks before you go:
My rodi is running between 55 and 60 psi. I dont see anything on the water report about silicate. But Aqua NC dose get its water from wells.Silicates tend to be one of the harder materials for a RODI unit to remove. Your utility should be able to provide you with their test results so you can find out exactly how much silicate is in the water they are sending.
Also keep in mind that reverse osmosis filters work better at higher pressures. If you don't run a booster pump and have low pressure you may get an improvement if you can raise pressure.
That pressure is pretty nice. What brand RODI unit are you using?My rodi is running between 55 and 60 psi. I dont see anything on the water report about silicate. But Aqua NC dose get its water from wells.
BRS 4 stage.That pressure is pretty nice. What brand RODI unit are you using?
If you have GFO you can run a pretty easy test. Before your next water change, treat your new water with the GFO since it will absorb silicates as well as phosphates. If you get a diatom bloom the problem is most likely your sand. If you don't get a bloom, the problem is most likely the water.BRS 4 stage.
No.Chris do you have a fuge ?
I'm having the same issue, I've been battling diatoms for around the 1 year mark, it started out as Dino's which a 72 hour complete blackout and sand bed change sorted out, then few weeks later I started to see diatoms just on my sand. Which I thought was because of my new sand so I left it to burn itself out as it normally would with a little help from GFO, My rocks are clear of anything just few patches of coraline, 1 year on I still have the diatoms on my sand, they re- appear a couple hours after a water change, I completely changed out all the filters on my RO/DI system, I also added 3rd prefilter for chlorine removal to help out the membrane, and fitted a DI bypass to get rid of the initial high TDS going I to the DI which was hammering the resin, that did not work, TDS has always read 0 even before the filter changes! I've tried algae scrubber and bio pellets within this year, they did not clear it, I then tried to reduce DOCs thinking they where the cause, so cranked my skimmer up, tried carbon, purigen, Dr Tim's waste away, my skimmer went crazy pulling out all sorts, but the diatoms stayed! just a few weeks ago I decided to do another 72 hour black out, and I reduced the intensity of my kessil a160s down to 25% from 60% I see improvement but i have a patch on my sand in the centre, which no doubt will spread as soon as my light intensity goes back up! Im running out of ideas! One thing jumped out at me reading through this thread, that is, my tank has never got to the green algae stage, so I guess that has to be my next approach unless anyone has any other suggestions?
What makes you doubt that it's diatoms?I've been battling what I thought were Diatoms for 2 plus years. Have tried everything!!
Silica tests 0ppm from RODI system, 0ppm from fresh salt mix and 0ppm from water in tank, test kit is salifertWhat are your silica levels?
Before moving to my 250g tank I had this problem in my 60g tank for about 9 months. Tried everything. All levels were fine, used chemicals etc. The fix for me was 2 fold. 1. I used kitchen 4 stage rodi water. Turns out it had reading of 19. I switched to new 6 stage rodi with reading of 0. And secondly I increased water flow considerably. Since then I haven't had any algae blooms of any sort.
