Hi I have my DSM done for 2 weeks and I have been very alert of the threat of mould. However, nightmare end-up appeared, I found some whiteweb inside my DSM tank.
I sprayed 1:4 H2O2 immediately and improved the ventilation by completely removing the cling paperfor first aid but it offered no significant improvement.
Then I flooded the tank in an attempt to kill the mould with suffocation but also in vain.

I keep browsing on the internet for possible solution but I can’t find any more practical advices. Could you please comment and advise ?

The mould likes minor, the DSM was a little on the wet side, My DSM lasted 12weeks and at time had much more mould than than, as my DSM progress and the carpet got rooted I increased the airing times, plus with it mine being a braced tank only used clingfilm for a couple of weeks, use to leave glass off for over 24hrsa at a time. Its always a close balance of moist enough for plants but not too wet for mould. Now you have flooded need tank to cycle so it will get a bit worse ( get the pH profile done and stable [CO2] - no livestock so the [CO2] can be as high as you like), once cycled a few amamos will soon clean it up

Thx so much for your prompt and detailed explanation.

After flooding the tank for 5 days, mould are found blasting at unprecedented locations inside the tank. Thus, I have drained the water and cleared the mould as far as possible. Meanwhile, I targeted those conspicuous mouldy areas and sprayed H2O2 regularly. Now I have returned and retained at DSM again.
Any more advices ?
