It sounds like you're having quite a bad day! I wouldn't write the whole hobby off because of it though, I bet you'll feel a lot better the next day.
Does it usually take 2 hours to do a w/c? If so there are ways to make it easier and you won't have to lug buckets around. Have you tried a python siphon? They connect to the tap and can suck the water our of your tank and also siphon tap water back in. They can be quite expensive but there is a nifty guide on this site that tells you how to make your own for half the price
. It should make things a little quicker and probably a lot easier. You would have to dechlorinate the whole tanks water volume before adding the tap water though.
With the filter, if you can't get on with it just replace it, there's no need to put up with all the hassle if you don't want to
.
It usually takes around 40 minutes, maybe 30. As i have to pick up the three mopani wood pieces, stack them up, siphon up the poop, now im swirling the sand as much as possible and smoothing it out, as the cory digs a little in the sand.
I was going to add a couple of platies or 1 cory today, but i thought id best leave it a little. The 2 platies i have seem to go from swimming around normally, then hanging around the back of the filter.. Ill test the water tonight. The 1 black guppy seems absolutely fine, no fin damage or loss of weight, and the cory is swimming top to bottom like crazy
The only sand I'm not a fan of is play sand, had no end of problems with it until I changed to unipac. It's very important to go through it with your fingers every water change to release the nasty gas build up.
Have you had it before? as i did once and i had problems then and ended up shutting the little tank with sand in down, i thought it was just me, as lots of members appear to have sand and praise anyone to do the switch, it looks nicer and i am shocked how much mess a few fish make! i noticed not so long ago, there were a few green patches in the sand. like algae?
with gravel, doesn't the waste get drawn to the bottom of the tank? therefore making it harder to clean?
I've had worse, unfortunately. The plague wiped through my biggest tank and I lost around 60 fish (a lot being various stages of fry... not big fish and thus not overstocked). Never could identify the problem as there were SO many different symptoms. I thought after trying various desperate attempts at treatments that one fish had made it... but a week after my tank seemed stable... that fish died too.
Oh this sounds a heck of alot worse! 60 fish! how did you manage to deal with that? Its so sad to find one dead all the time, makes it feel like a chore..
Get a good hob filter so much easier to maintain.
In 30+ years I've given up on the hobby two or three times, only to come back after finding a fish I've longed for.
I would say stick with it a while longer, if in a couple of months you still feel the same, return your livestock and store the tank. The bug will most likely bite again.
Sorry you're having so many problems.
I am going to stick with it a little while longer, just seems the fish i like are so weak, they look half dead in the shop, so what luck will i have? I personally love endlers, guppies and platies, they are never two identical (maybe the endlers) and have such personalities, explore all depths of the tank, and it doesnt take too many to look like you have a full stock
