RODI - What it is and why your reef needs it! 

Exactly, only buying what you need - it’s a high quality service 👍🏻

Agreed Daniel is the best in the business!

thanks mate!

Absolutely!

Just removed a brick, fed piping through then filled with spray foam. Works a treat :)

Hahaha yeah, that would create a decent algae bloom!!

Thank you

Thanks for the info!

the guys are second to none, super helpful and very well priced!

I'll see what I can do, it's just a latching relay design that you can now buy off the shelf from company auto aqua though

hey Matt, I just picked it up from my LFS. Great little units, super easy to add to any RODI system

Varies from unit to unit, usually 2 times the waste of clean water though

Great question! Usually around 1:1 or 1:2 and yes the waste water is great for the garden!

@@ParkersReef Thanks Sam. Been thinking about getting one - maybe the universe is whispering in my ear! 😂

Yeah I would highly recommend!!

Excuse my ignorance FTS? Not good with acronyms.

@@gjcoralfarm6929 I am not realy having any problems, water change every 10 days(works in with my shift). Change 140litres I have 2 x 70 litre bins fill up with the hose put in the prime then salt added (redsea pro) and mix. Same as for top up water from tap and prime, have poly filter, and carbon pad in the sump and thats it. I have a mixture of sps and lps coralline algae growing. Feed corals 2 to 3 times a week fish twice a day with spectrum probiotic food if I had a way of attaching a picture you might be surprised my local wants to know as to how I am doing so well. As it goes against most of the rules.

Glad to hear! I honestly wouldn't know how long mine takes as it is plumbed into an automatic setup so I never really see it come on or off :D

I have not ever used tap water before. RODI filters have been around a long time, probably a lot longer than we have been keeping corals alive for successfully in the home aquarium

Do you measure you TDS after the membrane? That is the best way to tell.

@@ParkersReef i only messure 1 before it goes to membrane after te filter, and one the product water to make sure 0 tds, maybe i should get another tds meter to messure between membrane and DI?

Yeah measuring between membrane and resin is a good idea. Let’s you know how hard the DI is working that wat

No silly questions here! I do have an RODI storage out with my natural salt water storage, but it is not actually where I draw it from for my dream reef. I have an RODI unit outside with my UV and chiller and it is on an automated system to keep a small 15L reservoir in my custom sump filled (turns on when empty and off when full, so technically doesn't keep it full - but does ensure it always has water ;) ) Your method would also work, you'd just need to use a peristaltic pump in place of the usual impeller pump for your ATO :)

@@ParkersReef Ok cool. So I could use a storage tank where I run my source water (HMA in my case) and use that for larger water changes. Then use a peristaltic pump to draw water from the same storage tank to top the sump up or do small water changes? I'll have a drain on the sump anyway as I know I'll flood it otherwise lol

@@chickenfist1554 yep - just make sure you're not mixing up your water change water and top off water :)

@@ParkersReef Top banana! Thanks :D

Hey mate! Oh wow, RODI unit is needed! If you’re in australia, get in touch with reef pure and let them know you heard about them on Parker’s reef! The team will walk you through the whole process from end to end. If you’re not in aus, let me know and we can chat

@@ParkersReef thanks will do. I’m located in Melbourne (SE suburbs).

Yeah hit up Daniel from Reed pure mate. You’re in safe hands

I put mine in the basement connected it to the washer fixture.

Must be down south with that TDS, here in West Yorkshire I get 60-95 TDS from the tap. If I were you I’d have a dual RO membrane and a booster pump to maintain constant high pressure (install a pressure gauge too)

yeah that is some SHOCKING town water! Good to hear the unit is getting it down to 3ppm, but yeah, you are going to burn through pre filters, membranes and DI resin. I'd potentially look to going to a commercial unit. Will cost more upfront, but the large pre filters will last a lot longer.

@@Hiskm just outside London so proper poor on quality

Exactly!!

@@ParkersReef Now need to get people on the message boards to realize that. Every time someone ask for a recommendation the answer is you need a 7 stage with booster pump and water saver add on.

you bet mate, video on these is out now :)

hahaha never know mate, perhaps when the other sub species of tangs go in :P

I actually have my RODI automated to switch on and off when my reservoir when it is full/empty. The storage is about 25L which lasts me about 2-3 days (but again, it is automated)

@@ParkersReef do you store any large drums for larger water changes?

@@benlee9647 I use natural salt water :)

Rain water takes up a lot of pollution from the atmosphere and takes a lot of filtration and ends up costing a lot more in membranes.

You can yes. Deionisation just purifies the last couple of TDS out of the water completely

Great question, I’m not sure on their water requirements. My limited experience of freshwater fish suggests it’s all about ph and hardness of water - but I really have no idea 😅

@@ParkersReef thanks bud thought I'd try my luck haha

I have Africans for the last 10 years and have only used a 0.5 micron carbon filter, and never had issue.. They are quite hardy so I suspect RO would be overkill.

Thanks tommy

True

That is correct yes, I could see how that is confusing. Extends the useable life from a membrane though as it will pickup any loose TDS from a membrane starting to slip

Oh wow I can only imagine how quick you burn through filters!!!

I have a whole house filter system that takes the brunt of the work first. I just replaced my 1 micron carbon blocks (x2) after 2 years. I don’t think I needed to but did anyway. I get my TDS down to 3 after pre, carbon and RO membranes the the cation,anion and mixed bed do the rest. On a side note the main prefilter for the whole house, I replace often every 6 months and it is disgusting how filthy it gets. Prefilter in my RO system is still white after 2 years. 👍🏼
