Lasses Dream Build

[Lasse]

I use this type of glass bottle.

The cork is drilled with two holes. One for the on/off tube and one for a safety tube back to the sump (the clear on the second photo. The drilled holes is tight to the tubes in order to force any overflow to flow back to the sump. The cork is also tight against the glass bottle. (it needs to be cleaned tomorrow)

Finally - some great photos of one of my Plectranthias inermis

​

My copper band - still going strong

​

My sun corals is growing good Orange and yellow

Thank you for the explanation and the photos. Are both tubes of the same diameter? It seems that the green one has a larger diameter. Are they 4 mm peristaltic tubes?

Are they 4 mm peristaltic tubes

Yes - freshwater air hoses but the green is PVC and the clear silicon. I use PVC for the suction side of my dosing pumps - silicon is IMO too soft in order to be a suction hose. In this case - the actual pump hose serve as both suction and pressure hose - hence PVC (that happens to be green) The emergency hose only works on the pressure side, hence silicon. The reason why I use the "stiffer" PVC tubes on the suction side is that I have noted that the silicone hose often will be sucked in by the negative pressure and therefore often gives a variable amount of liquid that does not agree with the calibration. I prefer clear PVC because it has been shown that some colored ones can leak tin but if there is light around I need darker hoses because of algae growth inside.

Sometime ago I replaced all the silicon suction hoses of the GHL dosers for the same reason. PVC in the suction side, silicon in the pressure one.

Have you made any test on the type of frozen food that may be dosed with the 4 mm tubes? Usually I manually feed a mixture of brine shrimp, mysis and krill on alternate days. I'm afraid that krill may be too big for the peristaltic tubes.

What I love about your system is that makes easy to feed non dry food several times per day. In that way you may think about keeping non photosynthetic corals. I love those Tubastrea!, although never thought about keeping them in my tank

I normally feed around 3-4 cubes of frozen artemia manually around 21:00 in the evening - all in at the same time but in different places in the tank. This manual feeding also force me to look at the tank and observe the behaviour of my animals at least once a day. Another reason is that I have a lot of bottom dwelling fish and hermit crabs - this way of feeding bring some of the food down to the bottom. You could change your schedule - only dose brine ans small mysis by the dosing pump during day and mass feed krill and large mysis at the evening.

If you have zooplankton pickers like some damsels, anthias, Chromis and so on - I would recommend freshwater copepods - IMO - there is no natural colour exchanger of red, orange and yellow that is better than that food. Its also perfect for tubastrea and clams

Doesn't seem to do too well with my fathead anthias after I drop it in. My Ctenochaetus binotatus doesn't seem to like it at all. For now it's in a corner - we'll see how it goes. It was in good condition when I got it but stress is never good for this type of fish. I possibly let it in a little too early but it didn't really like the cage - that's why it was let out. 3 days is usually enough - no fish showed any aggression towards it when it was in the cage. I have had surgeons with this fish before with no problems. You just have to wait and hope for the best

Great suggestion Lasse. Curiously, I also feed manually at the same time (21:00). It is the moment of the day I dedicate to observe the animals in the tank and check that all fishes are well and hungry. In the old times I used to do it drinking a beer, but my wife, wisely, recommended to drink less and now the beer is restricted, from time to time, to the dinner.
It is a very good idea to restrict the krill to the manual feeding and dose artemia and mysis with the dosing pump. I'll also consider the freshwater copepods. I have never used them. Which brand do you use?
