I was changing my Bulk Reef Supply (BRS) RO DI resin here a bit ago and couldn’t get the filter out of the canister. Looks like I put too much resin into the filter and is swelled up! I had to take a screw driver to the bottom of the filter to get the resin out. Lesson learned.
Over the past couple weeks I’ve noticed a few crops of green hair algae popping up in the tank. My first reaction to algae is to check my water quality. After seeing my water quality seemed normal I was a bit stumped. So, I changed my RO filters (sediment and carbon) when I first noticed the issue, then changed my DI filter resin (even though my TDS was 0) here last week. Then I tossed out all my top-off water to start out with the “new” stuff. So here’s a picture of one spot where it’s kind of bad. It’s a little over-exposed but it highlights the algae. Hopefully after a week or two I will see a noticeable difference.
My Bulk Reef Supply 75 GPD RO/DI system showed up the end of last week. I was amazed at how well packed it was! Everything was pretty much plug-n-play. Took a couple minutes to drain and disconnect my old Kent Maxxima RO/DI and a few more to mount and get the new one running. Here are a few pictures from the switch out.
Today is a happy day, my Bulk Reef Supply order got here! I ordered all my dosing chemicals (Calcium Chloride, Soda Ash, Magnesium Chloride, Magnesium Sulfate) for the year and a new dosing pump for magnesium solution. I’ve let me magnesium levels drop over the past year below an acceptable range so the doser should take care of that for me. I also decided to start packing my own RO DI filters with BRS resin. Looks pretty easy to do and quite a few fellow reefers do it.
With the increased photo period (sun) and heat I’ve seen an increase in hair algae growth this past month or two. So, hopefully the addition of 150 tiny blue legged hermit crabs will get the job done! I also changed my 1 micron pre filter and .5 micron carbon filter as a result of seeing my TDS meter bump up a couple points. If you’re not using a TDS (total dissolved solids) meter and System Flush Valve Kit you really should (IMHO), they are relatively cheap and the flush valve can help prolong the life of your RO filters (saving you $). The TDS meter will help you monitor the RO water input and output of the last filtering stage.
