A Simply Discus welcome to you darxvad.
Seeing that your anxious to jump in I would suggest you measure twice and cut once if building your stand. lol
My first question is have you had Discus before and how long has fish keeping been in your blood.
Mentioning Hans and Chad would indicate that you have already gone through some of the many useful threads.
- My suggestion would be to double up on the stand support posts as that extra coin spent can prevent headaches later.
- There is no need for actual plywood shelving and the perimeter support rails will be sufficient when flush with tank edges. What I would recommend is 1/2" styro-foam sheets on stand rails prior to securing tanks foot-print to cushion any un-expected stress points on corners.
- There are many paints on todays market that can be used on glass but would recommend lights colors...
- There is no need for casters but if you want I use solid hardwood blocks that will not allow water to absorb but even this is not really required if your extra careful.
- You can buy pumps and necessary equipment you need from one of many reputable sponsors on this forum.
- Again want to make clear to always measure twice and cut once....lol
Tank stand designs can vary....some want to hide sumps or pumps which require doors but the simple typical design is here just to give you an idea. This is a stand for a tank 4' by 18" foot-print.
Best of luck and feel free to enquire on any further questions you may have.
