This is the closest I can find to the brs reactor.

I would need to buy a pump for it separately though. Not a big issue though.

Could I run both carbon and gfo in one of these at the same time?

I had a dual reactor. I actually still have one. It's awful. The loss of flow into the second reactor was awful. If you can't find anything, I'd just DIY it. My DIY one worked the best out of everything I have run.
As for GFO and carbon together, don't do it. They both require different tumbling speeds to be effective. There are products out there that are 'combos' like this, but aren't specifically a carbon/gfo combo to accomplish the same goals.

Ok thanks. I will buy the h2 ocean one and see how I get on with it. If I decide I need another one I might attempt a diy one that I can hook up to the same pump but put in a gate valve to adjust the flow going to each reactor.

Got my handheld tds meter today and my ro water is reading the same as my inline meter shows (3ppm) I have ordered all new filters, resin and membrane for my unit so will see if that helps.

The thing I did find weird is that I put the tds meter in my top up reservoir it was showing a reading of 140ppm. Iím putting this down to maybe having some salt water left in my bucket when filling up the reservoir but Iím planning on cleaning it out and putting in fresh water and will try and keep the water clean.

Not sure if this reactor is starting to work or if Iím maybe just seeing things. It looks like the algae is starting to reside slightly. Hopefully it is shifting it though.

I also ordered some Cheeto algae today so hopefully this will come soon and try speed up the process of removing excess nutrients.

I have a question about replacing filters/media in ro units? I have got replacements for all 4 stages as my tds is reading 3-4ppm.

My question is - should I just replace one stage at a time or does every stage need to be replaced at the same time?

I donít want to replace everything if I donít have to.

What are you using for media? Make sure you flush the carbon block if it's in front of tfc membrane

Iíve bought a 5micron filter, an active carbon block cartridge, RO membrane and Di pod.

I was just wondering if I should replace everything or if one stage of the filter need replaced more frequently?

The DI needs replacing before most others ..Often 2-3 times before the others depending on the source water.. My unit shoots 10ppm with out the DI due to high TDS from tap [350+] There is a calculation that estimates most RO units remove as low as 90% of TDS..
The DI does the remainder..
The TFC should last up to 3 years if the other filters at maintained properly..
I run 5then 1 micron before my 2 carbon blocks..I change the 5 2x as much as the 1.
I change the carbon blocks every 6-9 months depending on how much I am using..
Replace the 5 often as it will prolong the life of all filters after it.

Ok thanks. What is TFC? My unit is around 8 months old so Iíll probably replace the DI resin, carbon block and the 5 filter. I dont think my unit has a 1 filter but my tap water usually sits at around 140-170ppm. Before I added he DI pod I was sitting at around 8ppm if I remember correctly
