question

[tim the toolman]

Do you have any type of surface skimming, overflow or canister surface attachment?

[subman]

if you can hook the skimmer up if not to skim at least for now to get some o2 in.

glass tops?

i do not have any surface skimming right now so i am really thinking it is low oxygen. should i use my old powerhead (it's really strong) to create more oxygen? i also have a power filter that is not in use. should i use that also?

[kwok]

no glass top. it's open. i will try to hook up my skimmer. i haven't opened it yet. was going to use it when i get corals.

[subman]

mixing the surface is the key right now. you don't need more flow, just get the existing one rumbling the surface

[subman]

what kind of power filter?
if is a aquaclear or similar plug it in and run it empty to stir it up

[kwok]

it's an aquaclear and i will use it to stir up the water. thanks

how much waves do i need cause it's making a lot of ripples on top of the water but i don't see any bubbles forming?

you dont need to have bubbles forming, if the powerhead is just rippling the surface that will suffice.


how old is this tank???

It's spring, and there could be something in your tap water that might have done this. This is why it is best to use RO water that is filtered before putting it in the tank. What type of conditionner do you use? It might not be enough to neutralize seasonal desinfectant that the water company might use.

At least that is my guess, but a small 20 gallons with 3 fish in there and no skimmer, just a small powerhead, could be low oxygen as well.

Could be a disease. How long did you have that wrasse that died?
