Trying NOT to feed the Tang

I’ve never been a huge fan of Tangs in reef tanks. You’d never have guessed huh? Still, my Kole is in their to do a job. Clean my seagrass of epiphytic algae and keep the rocks clean. Problem is, he likes flake and frozen a whole lot more. The cheek! Eating so much introduced food makes him lazy. Less browsing, more algae must ensue. To nip this in the bud I have been trying to search for food the Kole won’t eat. That’s not an easy task, after all Koles, like many Tangs, even eat poop. I have found two food types it seems to avoid. Floating pellets, in this case 0.5mm aquathrive, are one such. Cyclopeeze (frozen popsticle) is another. The Chromis devour both. The Jawfish will take a larger Ocean … Read entire article »

Orange/Grey Ricordea Yuma

I have been on the lookout for Ricordeas recently to add under the weir section. Found a nice Yuma at the LFS. I guess it sure would look better under actinics but here it is under my cool white LEDs: … Read entire article »

Dwarf Zebra Hermits

I tracked down some Dwarf Zebras at Real Reefs! I added 15 to start with – they really are tiny – to see how they go. Here are some pics: Hoping they will start sifting that sand bed. … Read entire article »

Video Day 112

I have added some new live rock under the weir this week in an effort to give the CHromis somewhere to sleep. They have ignored it completely of course! The diatoms/dinos are stillĀ prevalentĀ and I have started taking a toothbrush to the seagrasses and branch rock. The good news is it really isn’t spreading back to the rockwork very quickly. Syphoning it off the sand bed simply sees it appear again within a day or so. I’m going to try a few small hermits if I can source them (Calcinus laevimanus). These are reputed to eat cyano although there is much debate. Simply sifting the sand is good enough. I am now dosing coral snow (3ml) every day and also dosing Zeozym once a week. I’m a little sceptical but I have the pots … Read entire article »

Day 105 video

I have replaced the Vortech grilles this week with some diy mesh ones. These are removable and I might cut some of the mesh away to make the holes bigger. It is nice and thin and has improved flow in an attempt to increase the flow across the sand bed. It has seemingly helped drop diatom and cyano levels in some areas. httpv://www.youtube.com/watch?v=m-tFdHkBpcU … Read entire article »

Day 98 Video

Diatoms / Cyano still not going anywhere fast. The Jawfish completely re-excavated his hole this week Fun to watch. Sadly the tunicates faded so I moved them to the sump and then had to remove them. I have two small pieces surviving. One in the fast flow area in the sump and one in the weir cover just below the Vortech powerhead. They obviously need LOTS of flow to be happy. httpv://www.youtube.com/watch?v=GM2HVMcBoPU … Read entire article »

Seagrass Survey #1

This is the first of my surveys to count individual seagrass leaves in my aquarium. I’m hoping it will enable me to better estimate how the grass is doing. It’s quite simple, no chemical analysis is provided, just a simple count of new and old growth. Halophila Anecdotal Impression of Leaf Health: 4/10 (declining) Total Leaf Pairs: 87 Emerging Pairs: 8 Decaying Pairs: 9 Epiphytic Coverage: 30% diatoms Cymodocea Anecdotal Impression of Leaf Health: 5/10 (increasing) Total Sheaths: 54 Emerging Sheaths: 4 Decaying/Dormant Sheaths: 12 New Leaves: 11 Decaying Leaves: 19 Epiphytic Coverage: 20% diatoms Syringodium Anecdotal Impression of Leaf Health: 3/10 (declining) Total Sheaths: 32 Emerging Sheaths: 3 Decaying/Dormant Sheaths: 0 New Leaves: 7 Decaying Leaves: 3 Epiphytic Coverage: 50% diatoms (esp in upper reaches) Main Issues Diatom coverage of leaves. I have added several Strombus sp. to help ease the issue but they are unable to reach very far up the leaf … Read entire article »
