@Dash - your tank looks awesome, with some nice growth on your SPS

Have you had any algae issues with the tank? I assume you also use tap water for your top-off too?

I’ve never had algae issues until I started feeding more and using Reef Chili this year to get some colour into my coral. The colour definitely improved but now I have this one little clump of hair algae at the tip of my tallest rock (you can see it in the photo of my mandarin). I just need to find the time to scrape it off. Otherwise I think it’s pretty clean.
I have a ball of chaeto in my sump fuge and I think this helps. My previous 75 gal tank was sumpless & my old hang on skimmer was not great so I’d have the odd patches of cyano now and then. Nothing serious though.

Yeah, just tap water with Prime. I don’t have rodi set up.

I would imagine the chaeto in the sump and a good skimmer helps a lot.

Have you tested the TDS of your water supply. I’m curious what that would be in New West. I’m in the North Shore, and I believe my TDS gave me a reading of around .10ppm

I don’t have a meter but I remember someone else got a reading of 1-2. In all honesty, I believe any cyano/algae in my tanks have been related to flow & skimmer issues and I’ve experienced nothing more than a little patch here and there. I still need to work out my powerhead positioning but it’s tricky due to the sand & my rock placement. I believe the most important element in my tank is the live rock - which came from a very mature tank.

Just checked my water and got 013ppm from my meter. I’m wondering if this is too high to avoid issues with algae if you are only getting 1-2.

I used tap water and prime for 5 years, during that time I had two crashes, minimal coral growth more losses than gains, regular cyano outbreaks etc. Changed two things only kept existing flow, cheato, filtration,skimmer etc and rock formation and decided to go back to RODI ( which I had one a former tank in a former residence) bought it on ebay for $100 5 stage, no issues since had ti for a year now and excellent coral growth. I wish I could say it was all down to the RODI but I also discovered my lighting par was in the toilet at the same time so I had to change my little two, but the combination of the two solved all my problems. I do get some algae on my glass but I put that down to light coming from my window and I tend to have my lighting bright for long sessions. IMO rodi is a no brainer, all the best tanks I've seen in the lower mainland use RODI's far outweighing those that don't. Best of luck to you

Our water in the gvrd has almost no dissolved solids, even discus breeders need to harden the water a tiny bit.

I do not believe there is any reason for rodi water. Buy an inexpensive deionizing filter to polish your water. Our water has chloramine I believe, you can remove that with prime or the DI filter.
On the bright side if you do go with rodi filters your membranes should last a very long time as there are no carbonates or bicarbonate to remove

Chloramine is not used in treatment in metro vancouver. They use UV, Ozone and Chlorine. Aging and aerating the water will remove any chlorine

Hey, I am not the most experienced reefer but I do run an sps dominant tank. Sps are very $$$ I would either buy rodi water from jl or find a way to make rodi work.

My accommodation is located in the Denver zip code area. My tap water is quite fine I would say. I know that a few of my neighbors have even tested it for any harmful components and additions. And everything proved to be within acceptable limits. However, I never use tap water for drinking. I have invested a good sum in a powerful filter to be on the safe side. I prefer to stay protected just in case.
