Pond Compost

Hi aquatic planters!

I've got hold of a little second-hand tank to grow a few plants in preparation for my bigger tank project.

I've also been given a bag of old 'Tetra Pond' compost. Is it suitable to use as a 'Walsted-type' tank? I can't think why not? I was planning on putting a 25mm layer and then a 25mm layer of sand.

No fish in this tank, so I was just going to filter but not heat.

I'll be trying the super glue Java on a bit of Mopani wood, and also on a bit of coconut shell. I've also got some Lilaeopsis brasiliensis in my 40L that doesn't seem to be doing very well, so thought I'd plant it directly in the substrate in the plant tank.

Thoughts and suggestions please?

Is 25mm about right biffster? Any additives needed?

Hi NM seems like we have similar thread, i'm trying to find suitable compost or plant base layer under my gravel, my tank will have fish in and i don't want to raise Ph, (some have lime in ) so got some googling to do : ) I'm beginning to appreciate the plants as much as the fish lol

plant compost is not aquatic approved compost
and can leach all sorts of chemicals in to your tank
only use aquatic approved compost its safe for ponds
and aquariums normal compost is very high in nitrate
and phosphates the concentrations are so high it will kill
fish off and encourage algae 

Sorry, I meant "plant compost for ponds" .....................
