I did the math - it isn't a few bucks to replace these filters, lol. More like $150 minimum and $230 for the premium stuff... Thanks for the info. So, if the membrane is shot, then I should see TDS creep once I get the system up and running and producing some water.

Thanks for the info. Should I replace all the filters, including the RO membrane? I agree with avoiding an issue in the future, such a shame as these really don't have much use.

What are the risks if I use the existing filters and they are producing "0" TDS? Just curious, if I can use these existing filters it would make this a really good deal, not such a good deal if I need to replace the membrane, pre-filters and 2x DI?

Bruce - It is from the TDS meter built into the RO/DI system, so it is inline. This is the exact system, except that Spectra Pure has updated the membrane and some of the pre-filters - http://spectrapure.com/RO-RODI/RODI-SYSTEMS/MaxCap-Manual-Flush-90-GPD-RO-DI-System My system has: .5...

I'm piecing together equipment for the new set-up and scored a 5-Stage Spectra Pure MaxCap-90 Day RO/DI yesterday for a great price. The unit was built in 2012 but looks brand new, and so do the filters, however they have been partially submerged in water and in storage for many years. The...

I don't - I am usually connected to my corporate VPN 100% of the time. I've seen some advertisements out there, but be really careful who you trust your data with. Once it is on their network, they have access to it. Honestly - a huge upgrade that is free is simply point to Umbrella's DNS...

You are correct, if the device doesn't need to reach out to the internet, it doesn't need any "open" ports. However, opening a port on a firewall doesn't mean that it simply allows any traffic through that port. There has to be a request from inside of the network out, not the other way around...

I'm in tech and I don't agree. Many of my company's products require that Enterprise "opens" a port on a firewall, in fact, we have an entire list of ports that need to be opened. It is an incredibly common practice and a necessity depending on how the firewall is initially configured. Also, any...

Yep! Once I get the OK from the landlord, I'm placing an order. I just purchased a Giesemann Spectra on eBay, I can't get away from halides! This time though, I'll be running a SE so I can use the Radium bulb :)

The tank looks great and I'm happy to see it is getting good use! It is a 75G, by the way! lol. I see you're selling those halides, that was such a cool set up and a steal of a price for what you're asking. I think I paid like $350 just for the Manta bracket!

I do have peppermint shrimp and snails(Blackfoot trochus). I have already banned my green emerald crabs to the sump. I am 100% on green emerald absolutely devouring birds nest SPS and similar structured coral. I bought them for bubble algae and they don't even know it's there...They have so far...

Sorry about the poor quality photos guys. I took a screenshot with my iPhone because the triton website was making it difficult. Tin is elevated but there is not a lot of discussion regarding tin except that it can be toxic in high concentrations. However, there has been a suspicion in the...

Here are my results: Tank keeps melting acros after an exposed magnet debacle and I wanted to see if this would show any tell tale signs. Not much of anything, really.

If you have time (a few weeks), I would also recommend dosing Lanthanum Phosphate to a tub of the rock and RO/DI water. The Lanthanum binds to phosphate and precipitates the phosphate from the water. I did this after a muriatic acid bath. I originally purchased BRS Pukani, which is beautiful...

I'm old school, haven't seen a great benefit for scrapers except to use them as an extension for my Mr. Clean Magic Pads. The Cal Academy uses these things like they are going out of style and it is by far the best and cheapest solution for cleaning both calcareous and non-calcareous algae from...

Just got through treating my tank with Interceptor Sentinel. I dosed the entire tank and removed as many hermits as I could find, though I did lose my Fire Shrimp on the first dosage and then I lost my pistol shrimp on the second dosage 7 days later. The pistol didn't have time to recover I...

Ok, sorry to be a such a slacker, here is an update. Still working on fine tuning Zeo and getting my colors locked in. I just went through a red bug infestation so I am hoping that a lot of my acro color issues were due to the red bugs. One other issue is that I am taking my Zeoliths to the...

About 100 meters from what I have heard. -Mark

Thanks to everyone who so graciously offered their time and fantastic reefs! It was a pleasure meeting everyone, look forward to the next event. -Mark

Did you send out an address list earlier? Would like this if I need to meet direct at muir beach. Mark
