I’ve a recovering overfeeder from my freshwater days, thought I had this nipped in the bud but now I wonder if that is the case. Let me give a timeline..
I read that nano’s can be very difficult w/big swings.. is all of the above just par for the course w/smaller tanks? If so, I can see why people give up. As mentioned in a prior thread, another LFS & long time customer both tore their entire tanks down due to the brown/indestructible muck I described.
I was planning to upgrade tanks in about a month but have serious concerns I’ll carry over bad behavior.
- March – set up tank (20G AIO)
- June – everything good, fish good, parameters stable/good. Feed my 4 fish + CUC ( 2 domino clowns, YWG & RG) ¼ a cube brine shrimp every other day w/the occasional add’l ¼ cube of mysis just for variety.
- July – wanted a more natural looking scape so I moved everything round & added 4 SPS coral frags w/left-over rock from the initial build I had in the garage.
- Aug – start seeing some brown/red/purple algae, thought it was diatoms, let it go
- Sept – scape is clean as a virgin’s… morals but my substrate looks horrible. The algae clumps up the sand, doesn’t blow off & just spreading like wildfire. I start dosing.. no change. After much reading, buying a cheap microscope & concluding I had both dinos & cyanos, removing about 4lbs of that substrate & replacing it I opted to increase my nutrient levels to ¼ of a cube (Hikari Bio-Cube Brine Shrimp) each day. I remove the rocks added in July, bought a tailspot blenny to help control algae and insert DIY frag rack
- Mid Sept – algae is gone, scape looks good, parameters good. I removed the RG for being a bully and replaced w/purple firefish.
- Oct – the brown muck is coming back, my nitrates spiked to 80-160 PPM, my scape is turning green and I now realize the water I had been buying from my LFS water has 10-15 PPM nitrates! I’ve got the nitrates down to 40PPM +/- and will do another water change this weekend w/my own saltwater, I just need to find RO from another LFS.
