I changed filter to a powerful external canister and lighting was changed to
marine spec, plus airstones galore but still low oxygenation?
Should I just give up an stick tropicals in it?

Help, first time I have found this newsgroup. I am *TRYING* unsuccessfully
to set up a Trigon 350 tank for Marine. Despite everything I try, I cannot
get the water to a high enough oxygenation level. My dealer now says
Trigons
are not designed fro Marine? Anyone offer and advice - PLEASE.
