Changing a substrate

[plankton]

Only use fish that eat snails as a last resort, if you don't overfeed you shouldn't get a population explosion......(there are much smaller loaches that do the same job, but all should be in a minimum group of 6 )

So what else would be good to have in my tank?
currently I have..
8 neon tetra
1 angel fish (she killed the other)
4 dragon tail guppys
1 leopard tail guppy
(both guppy types have been a nightmare and killing each other but now seem peaceful)
pleco (soon to go as he will get way to big, miss sold as a small one)

I think it's time for a new thread, as this is a sticky about swapping substrate

Interesting thread, I am going to change over to sand. I actually have the sand I am just building up to doing it 😂

[dinofred1]

just wondering, could it be done in section say 6 inch wide strips at a time, take out a strip of gravel, use something like drain pipe to get the sand to the bottom of the tank.

Some good advice in this post.

I'm about to tackle this very soon in my 70l tank; I'm switching from gravel to sand. Only I've had extra load of biomax in the tank for a few weeks leading up to it to help hang onto the bacteria, can't do any harm, right?
