adding aeration to tropical 200 litre tank

[LuluH]

please advise - I've had this size for 6 months, upsized after 3 years with 80 litre, so naturally, i bought a few more tank mates from sociable categories at local aquarium shops in UK. sadly i lost 2 baby plecs and 3 corydoras (albino, one young, two from the previous tank ) all around xmas time. All my water levels check out ok, i have plants and bogwood.. weekly 20litre change and Fluval F3 external filter ( with carbon )... fish shops were perplexed.. no other species passed. I have Large African shrimp and 4 others that are so docile . what could it be in a 200 litre tank effecting newly introduced imported baby plecs and Corys - is it to do to with their unusual armoring makes them more sensitive ? there is now algae bloom on glass,,, and like i say 2 albino corys from the smaller tank lived here for 6monhts, after over one year in my keeping. I went local where i b0ught them from and one pet shop suggested extra aeration could be needed - I have a bubble stone strip on tank floor and wide spray bar beneath the water surface all holes are fucntioning .

You can get power heads to add extra aeration to the tank: https://www.amazon.com/s?k=Aquarium+power+head&ref=nb_sb_noss_2&tag=ff0d01-20

is there such a thing as a quietr one ? ? this is an interior tank and some of these items are sold for ponds etc where sound is less of an issue over cost

They do make some that are meant for inside tanks... I believe some are in that link I gave you. (Most are quit noisy though. )

my previous submersible filter was a fluval u3,, it wasnt noisey - it has lots of spouts/ flow options - is it suitable to pop it back in without the filtration pads to add aeration or is that not sufficient ? ( and quite large ). https://www.amazon.co.uk/dp/B001TKZ51E/?tag=

Yes, it’s perfectly ok to put a filter with my media in the tank, for added aeration. (Do you have a filter with media in that tank?)

currently, i am using a larger Fluval F3 external ( in the cabinet below ) filter
I took my smaller fluval U3 out after a month of tank setup... but its clean ( was going to sell it ) so can put in back inside for aerating pueposes - should i leave out the sponge filters and carbon as this is being performed by the big one under the tank. thank you

You can leave them the sponge/carbon in if you like. Having more filter action could never harm anything...
