I couldnt find details of the exact set up to incubate the eggs online though. I scooped the eggs out with a cup. The times I left the eggs in a separate tank with and without aeration would have meant that the incubation tank wasn't at the same temperature as the main tank. But the times I left the eggs in a sock in the main tank, the temperature should have been the same.

Hey guys, my mandarin pair have been spawning rather consistently over an interval of 3-4 days each time. I have never managed to get the eggs to hatch though. I've tried the following methods after catching the eggs: 1) in a nylon sock and floating the eggs in the DT 2) in those coffee socks (unused) and floating the eggs in the DT 3) in a small tank with only water from the DT and bubbling air 4) in a small tank with only water from the DT and no aeration All of these methods basically did not result in any mandarin fry. Any suggestions to incubate the eggs? Thank you

Probably depends on the livestock I guess. But don't fishes get pushed around quite a bit by the current in their natural environment? It is a must to insulate or else confirm too cold. If you're using a bottle, must make sure that you don't fill all the way to the brim and squeeze the bottle a little before closing it up. The pressure is lower at higher altitudes and not doing that could potentially rupture the bottle. Left with frozen fish like that haha

In all seriousness, I think red sea coral pro salt is good. I just NSW from LFS to culture rotifers and red sea coral pro salt for water change in my DT

I've brought fishes from Bangkok and from taiwan. All small livestock though. Just put inside a small mineral water bottle, insulate with Styrofoam and pack inside check-in luggage

Dasani has magnesium sulfate added. Tap water is usually unacceptable due to the levels of phosphates dissolved

Maybe can try Morton Iodized Salt too

That's pretty cool. I'll probably try to DIY something similar (:

I tried feeding mandarins ebiko before lol just wash thoroughly first. PM me if you cannot get them to eat still.

Carbonate salts and the corresponding acid result in a buffer solution at the proper concentrations. Increasing the pH may theoretically also increase the kH. Theoretically because the alkali that you add will most likely react with some co2. I do not think that the increase in kH through the addition of NaOH will be dramatic though. Adding sodium hydroxide is dangerous because its a strong alkali that can cause the pH of the entire system to shift dramatically though. As for which products use NaOH only, I'm not too sure. Unlikely to get it off the shelves though because its a strong alkali and is very caustic.

My pH is around 8.2 and kh is around 9. PH is a measure of the relative quantity of H+ ions and kh is the measure of the water's buffering ability. An increase in kh is usually done with carbonate salts. The salts of weak acids give relatively alkaline solutions when dissolved. The buffering capacity of a reef tank is mainly done with the relative concentration of carbonate ions and is an equilibrium with the corresponding acid(arguably carbonic acid or maybe just carbon dioxide). I'm not too sure what product you are using to raise the pH but it could be a dilute solution of sodium hydroxide. It will raise the pH but not directly affect kh (unless it manages to react with sufficient carbon dioxide dissolved). I suggest using sodium bicarbonate or sodium carbonate to raise kh.

Damn nice!

Try testing your iron levels. I've been using a par38 grow light and the growth of chaeto only really went crazy after I started monitoring the iron levels.

Some Zoas/palys are poisonous. When fragging them, they could potentially squirt toxins and there's a chance of it getting into the eye.

Hi all, I'm looking for s strain live rotifers and hopefully, some phyto paste to culture them too. Thanks.

Very hard to catch it. Most of the time the greater part of it would be hiding in the rock so if you were to use a lot of force... You'll get 2 halves of a worm lol only way I've managed to get one out was to take the entire rock out first.

Wouldn't the water level in the bottle quickly equalise with the level in the trough?

Depends on the dimensions of your tank. There are calculators online to help you determine the minimum glass thickness you would require.

Maybe some soft corals? Zoas, Xenias, mushrooms etc

Nice. The set-up looks really neat. Are you going to keep corals and livestock endemic to your location? Especially since we always see shipments from the Philippines.

I have had problems catching fish and what I did was to wait a few hours after 'lights out', then used a torchlight and a net to catch the fish. They are a lot less attentive/alert and easier to catch.

I've tried using them before. The plastic is pretty elastic so it appears to "heal". Small scratches seem to be not much of an issue but obvious punctures to the bag would render it unusable already.

Thanks! I'll check it out with CF (: I only saw the common ones at pacific marine though.

Thanks (: I'll take note of the pointers. Must go find the active ones now and wrap in newspaper after buying haha

Oh okay :/ perhaps I will try again then. It seemed like there was quite a bit of water though. Maybe I'll request for an even bigger bag this time. Thanks!
