    Redsea Reefer 450 Build / Upgrade

    Drill the rocks and use acrylic rods to stabilize the structure. You will be glad you went through this effort long term.

    I'll take 11 and 9. Thanks

    Is an mp40 available?

    Par meter

    I sealed the wet and up with silicon to make it waterproof. It comes in handy from time to time when trying to figure out where the bright/not bright spots are in the tank.

    Yep! You still got yours? Let me know if you need another frag.

    Yep I’ve read it, great recommendation. I have experienced more than one crash over the years due to most likely DOC from the excessive algae once the balance of the tank is upset. Sent from my iPhone using Tapatalk

    Thanks! Few of those corals are from you. I think that red robin is invasive, lol.

    New Year Update! My tank has been running without a skimmer for over 6 months now. Since removing my skimmer, I have noticed an explosion of sponge activity in my system. SPS corals are growing at a faster rate as well! If you look closely at the pics you should see white sponge in all of my shaded areas of the tank. The rubble I keep in my sump is covered in sponge as well. I am now dosing BRS 2 part at over 130ml/day, and I have been able to keep my parameters stable. PO4 runs anywhere from .05 - .1 and my system seems to look the happiest when PO4 is on the lower side of that range and algae growth is slow and manageable. I ended up having to dose potassium nitrate to bring my nitrate up to ~5-12PPM. This was only needed one time and it’s been fine since. Before dosing the KNO3, nitrate was undetectable. I did have an issue a few months ago where I could not get my calcium level above 300ppm, I was dosing about 2x the amount of calcium carbonate as compared to soda ash and still could not get above 300. Then one day it started snowing white stuff in in my tank (calcium precipitate) with my CA still at < 300. Scratching my head, I tested my Mg at < 900ppm. Once I corrected my Mg my CA shot up to 450 and my Alk decreased from 7.5 (sweet spot for this tank) to 5DKH! Everything has since stabilized, while I’ve read about magnesium’s role in the reef aquarium, I’ve never watched it that closely. I will be testing it more often now! Since running without a skimmer, I have observed a few things. When my coral are not happy, (visual observation) nutrients spike up significantly. I assume that these issues are more pronounced in my system given that I have no filtration other than the coral and sponges. Without careful observation things could spiral out of control quickly with algae wining the battle for nutrient consumption and upsetting the balance of my reef. I keep 8-10 fish in this 80-gallon system and various inverts (snails, urchins and a few crabs). Typically, I do a 4-5 gallon a water change every week and most of my maintenance time these days is dealing with corals growing into each other. Check out my tank from a little over 12 months ago: And today (just cleaned, corals are a little peeved):

    Hair Algae with good water?

    Persistent manual removal (including scrubbing rocks with a toothbrush) and small weekly water changes will likely do the trick. it's important that your corals are happy and consuaming the nutrients in the water column to out compete the algae. You will never be 100% free of hair algae IME.

    Alternatives for Carbon & GFO?

    Not trying to be an acronym Nazi but I figured I would correct a couple of things for those that might be confused: GFO = Granular Ferric Oxide (Phosphate sponge) GAC = Granular Activated Carbon (Absorbs contaminants from the water) GAC is what may contribute to HLLE.

    Update! It’s been a while since I’ve updated and the tank is doing great! This time around I’ve been doing things a bit differently with my reef mainly surrounding nutrient levels. My tank is now running "all natural", no GFO, no bio-pellets, no skimmer!! I do not have **any** chemical or mechanical filtration in place and things are doing great. I do have a GAC reactor running to mitigate any coral warfare and any other impurities that may get introduced unknowingly into the water column. I’m loving my new lowtech approach and am currently dosing over 100ml of 2 part a day (this is the highest consumption I’ve ever had with this tank). This amount of consumption does make me a bit nervous as a small mistake with my water chemistry could have dire consequences for my reef. I think I need a bigger tnak!! 😊. With the higher nutrient levels, I do have to deal with a bit of algae/cyano. I think I need to add a few more snails and urchins to help with the hair algae but the cyano is ever-present. I simply syphon the cyano out weekly with my small water change. Looking forward, I like tanks with very large acro colonies and I’m excited that mine are on their way to becoming quite large. Things really are in need of a “haircut” as several colonies are touching. Here are a few pics from today.
