i tried to follow the guideline of smallest fish first on initial stocking, with bigger fishes (tangs) last. but after a while it is just all random, as the smaller fish may die, or finicky fish just not eating, and you want to buy a new small fish to replace them, or you saw a nice fish you want to keep etc.. in the end it also depends on the fish character - there is fish that is small but smart and has fighting spirit, so it survived even when bullied. and there is fish that is timid and gave up easily when bully - so starve to death, even though they may be the same species and introduce at the same time.

i second the nyos 300 - if cost and space is not a constrain, even if you have a refugium. not everyone can successfully grow macroalgae consistently, but a skimmer will be consistent.

it depends on what you plan to keep and your budget really...

nice collection of rock flower anemone!

cool! i think you should just switch to mushroom coral tank and sell the sps

yes looks ok to me too since you are dosing bacteria. good luck!

cycling of tank means you want to cultivate/grow beneficial bacteria in your filter medium (in this case your live rock), so that the bacteria can convert ammonia-> nitrite -> nitrate. you mentioned you did 3 water changes -> it could means you replace the water that has ammonia/nitrite with water without ammonia. if you leave your tank as it is, without doing water change, and test for ammonia and nitrite, do you see value? your cycling is complete when your ammonia and nitrite is 0. (without doing water change) then you do water change to control nitrate. since you also have 5 hermit crabs already before your tank is fully cycled, when you do a proper cycle now your crab may stress or die.

All collected. Thread close

Reserved for collection this evening

for those who keep wrasse do you have a hood or netting for your tank? i don't have one as i think it is troublesome but i recently have 2 jumping incidents in 3 months...

my yellow wrasse decides to go floor surfing today after 1.5 years...

6-line will make a protective bubble in the rock when they sleep. i have a few wrasses too - 6line, yellow, fairy, vrolik and recent lost a carpenter flasher wrasse. cannot find him anywhere in the tank. it's difficult for me to introduce new wrasse now as the 6 line can get quite aggressive with new wrasse.

how big is your tank and do you have a chiller?

in theory UV doesn't kill bacteria but alter their cells so the bacteria couldn't reproduce. so by right the skimmer should still be able to skim what bacteria is coming out of the biopellets. the setup should be biopellets output to skimmer input, and uv the last equipment before return pump. how big is your tank and what skimmer are you using?

both serve different purpose, one is to control disease, one is to control nutrient. depends on what you are keeping, if fowlr and you have many expensive fishes, i will choose uv. if sps dominated tank i will choose biopellets. if you quarantine your fish properly u don't really need a uv. btw - uv and biopellets can operate together. you need to first let the bacteria to colonise the biopellets. once biopellet is working you can run uv.

i think u need at least 2 hydra52 for 422 tank

fresh n marine

it could be many type of different worm but if you rather be safe than sorry, you can remove the rock. monitor a while to find out which rock the worm stays and take it out.

if you had already check that the recommended water level is correct, and the skimmer is already break-in, then i guess it is not foaming because there is nothing to foam - you have low bioload or no organic in the water. oversize skimmer sometimes will have idle time.

lfs = local fish shops

lfs will have the cuc. trochus is quite hard to find (at least for me... i cannot find them), so alternative u can get astrea snails. downside is they cannot flipped back up if they fall on the sand. a couple of hermit crabs will also be nice- but they are hit and miss some people have experience they will eat coral if the coral is dying.

how many fishes you have in your tank?

still usable
