Hi Folks,
Unfortunately, I don't have many shops near me that sell rock (that isn't marine live rock). THe purpose of this tank was to be low budget.
Most of my money will go into my large tank which will be set up near the summer.
As such, I am just going to use the rock I have to get this wee tank up and running. It may not look as good, but the purpose of it was to learn from mistakes, trial the DSM, learn more about dosing and keeping plants.
I have glued some of the rock in place and have added plants to start the DSM process.
Thank you for your help with this. Your words haven't fallen on deaf ears! It has purely come down to budget. I set an amount of money aside to buy stuff. After getting a lot of things (plants, chemicals, heaters etc) plus a light, there is no money left without going into my main tank fund!
So, I will take your advice, mistakes in this tank and all other experience to make my main tank a show stopper!
