Selling for 7 dollars, approximately 7-8cm. It is terrified of other active swimming fishes in my tank so it hides and doesn't come out to eat at all, if you have a calmer tank with only very few active fishes please take it off my hand asap. Something like a nano with just a pair of clowns or just by itself would be great. This is not a problem with this fish in particular but all fire gobies, as all the other fire gobies i had all act in this manner. I'll try to find take a photo later today.

A quick review on the Clarisea Gen 3 Fleece Filter. Looking back, my old Clarisea Gen 2 (SK5000) has been running since April 2018. A longer fleece roll was introduced around June 2019. Increased from 25 meter to 40 meter (Same spec @ 20 microns. And for the same price). The Clarisea has been a game changer on my tank husbandry the past 3.5 years. Previously, I had to change the sump filter wool every 3 days to mitigate rising nitrate levels. With the Clarisea, the filter fleece is replaced just once every 2 months or so. A common question I’ve been asked is whether the Clarisea is worth getting. I will probably never ever run a tank without the convenience of it. I got hold of the Clarisea Gen 3 recently to replace my 3.5yr old Gen 2. Its similar to the Gen 2 but with some nice improvements from assembly & usability point of view. I understand that there is no change to the fleece, motor & controller. Did some sump work today & its a good time to take some pics & provide actual usage update. As a quick recap during unboxing, the main panels came assembled out of the box. Just need to fasten a few more pieces after installing the filter fleece. Gen 3 has a stiff roller to guide the fleece. This will prevent the fleece from bunching up like this seen in early Gen2 batches. The root cause is the white plate bends under the force of the taut fleece. And the curved shape of the plate causes the fleece to bunch up. I recall seeing current Gen2.5 version with this stiffener roller implemented already. Underside view : I typically allow about 30% of the water to pass through. The bypass adjustment is now more accessible and located under the inlet pipe. I leave mine slightly open like this Though some people may want to close it entirely for max filtration efficiency. Fleece removal tool. This is a convenient accessory to have. No more manual unwinding or cutting the dirty fleece with a blade. Just place the tool under the fleece & push down. Then push down (with 2 hands) The clear acrylic panels are removable without any tools. It simplified the initial assembly process & makes it easier to take things apart when its time to give the unit a thorough wash. Looking at the picture, I just realised that I had assembled the used filter fleece incorrectly. You can see one end lifted off the acrylic. This happens when the motor wire is orientated to the bottom. The correct orientation should be this. I previously had a bad experience of the motor wire cut by the sharp acrylic edge. Got it serviced at Reef Depot (btw, good after service & warranty support). You can see from the picture below that Gen3 has a feature to prevent the the motor wire from being damaged by the acrylic edge. The fresh roll of fleece is supported by this simple acrylic holder. This design positions the fleece perfectly perpendicular and has less friction compared to Gen 2 holder (where the cardboard core is held by 2 sponge inserts). Less friction probably means the motor won’t need to work so hard. The fleece extension kit is now sold as a separate accessory. This is for folks with limited space & need to move the fresh fleece upwards. This is a pic from my old setup. Nice to see design principles deployed at the float switch to eliminate use of fasteners. The float switch shaft needs to be cleaned occasionally. Simply slide it off without the need to mess around with screws & nuts in that tight space. Tops down view showing the clean side & dirty side. To sum it all up: The Clarisea eliminates the mundane task of changing filter wool every few days. The latest Gen 3 performs similar to the previous Gen2.5 but has nice design & usability improvements.

Memorable & possibly last visit to Coral Farm over the weekend. Going to miss the place. Got a couple of invertebrates Got a tiny serpent starfish (ophiolepis superba) to take care of detritus in the rocks. A sea cucumber (holothuria edulis) And some bumblebee snails to take care of vermatid snails and detritus. Did some relayout of equipment in the sump. Moved the ATO container outside the cabinet & moved the Kalk stirrer inside. The sulfur reactor is working well so far. The black stuff seems to appear when its exposed to light. The other side of the reactor that faces the sump is clean & yellow. Nitrates running around 2-5ppm. Not bad for quite heavy feeding. Right now i'm feeding frozen food equivalent to about 5 mysis shrimp cubes a day + pellets.
