Dissolving Plants???

[brishe]

I am currantly restarting our tank due to persistant disease.

I brought some plants from waterplanz (trademe) an awesome deal for over 40 stems of plant, all varieties, anyway i planted them as soon as i recieved them and two days later some of the plants are going opaque looking and dissolving away, some are getting small black spots too and going holey.

The water temp is 27c and there are no fish in there yet.

Any idea what this could be, and what i can do to save my plants??

Thanks in advance.

His plants are good but grown emersed and they may be having a problem converting to submersed growth.

It is hard to advise without knowing your growing conditions and what sort of plants you have.

Most of the plants look good when they arrive because they are grown hydroponically.

Now a lot of serious traders on TM state categorically "grown professionally" or "grown submersed" or "grown in my tank" etc. Wonder why?

I have bought these emersely grown plants from petshops in the past und some will survive but most won't. I didn't know any better at the time.

The problem for the commercial grower is algae growth and snails in the growing tanks. That is why most of these "water plants" are grown emers, hydroponically. No snails, no snail eggs and no algae. Beautiful clean plants, grown extremely fast in a plastic house - you can cut and sell them weekly. In the tank however a lot of them sadly turn to mush. And that also happens in the pet shops by the way! I have seen very bald stems there myself.

There is nothing much you can do except pinch out what is still alive, remove the sludge of the rotten ones and hope for the best!

Come to think of it. Could it have been cold damage? Don't they come from the South Island? Wonder if they were out there in a cold night and got damaged?

Col can be a problem but it is more that it is more difficult to convert to submersed growth when they have been growing emersed in cold conditions.

Thanks for all the info, some are definatly growing but alot of them are looking aweful, i will just have to see how they go.

Definatly wont be buying plants online again.

We dont have a huge selection of plants at our lfs.

I've bought plants from waterplantz before and I've only gotten one type of plant that's been grown emersed - and it was quickly (in about a week and a half) converted to submersed form once it was in my tank. All of the plants I've got from him are thriving. I'd suggest that the problem with your plants lies in a lack of light/proper nutrients.
