JohnL's 20 Gallon Nano Reef

I think he found some that were rusting on the inside due to poor seal.

I am a huge proponent of never submerging a heater head for that reason. The element reaches ~800 F. And the rubber, epoxy, silicone expand at a different rate from the envelope. Leaks are pretty much inevitable.

Good idea!

I assumed the membrane would remove most silica and regular DI resin the rest. I guess that is not the case?

Apparently

Unless there is some problem with your membrane, or the way you collected the sample, or the way they processed your sample, or the technician was at the beach that day...

I do. I use a BRS value 4 stage with mixed bed DI. What would be a good way to add a pure anion stage?

John, here’s what I run:
Stage 1 - micron
Stage 2 - 5 micron carbon block
Stage 3 - 1 micron chloramine carbon
Stage 4 - RO
Stage 5 - Anion
Stage 6 - Cation
Stage 7 - Mixed Bed resin

Sounds perfect George. Thanks

John, preface to say I haven’t read the whole thread.

I pieced that together from an ancient SpectraPure 3 stage unit, an add on single stage micron, an add on BRS dual stage DI unit and and add on BRS single stage DI unit. I also added a AquaFX booster pump because, after adding a pressure gauge, I learned my water pressure across the membrane was not high enough.

ICP Test Results

I can open the RO water results but not the tank water PDF.

I emailed you a copy.

Maybe if you get a larger tank with more water volume you can dilute the problem to acceptable levels

Simple

Buy a bigger tank

Don't encourage him George.

I’m not, I’m encouraging you

Give him time. Things like these need to be approached delicately.

So is even dosing Iodine worth it?

Activated Carbon and Iodine

I'm trying to raise my iodine, iodate level from zero. Do I need to remove my activated carbon?

forums.reefcentral.com

GAC will strip Iodine very fast. I don't use GAC for this reason. I will only use GAC temporarily to remove a treatment or for a specific purpose.

My Iodine dosing might make some cringe. I dose 20ml every other day and only test every couple of months. If the crabs are molting then I know there is Iodine in the system. Call me crazy I know

What kind of iodine? How do you test?

One week after removing urchin and adding 4 sps frags. No recession other than on the plug that the millipora is mounted on. Hopefully that is from handling it.
