Ok so we're in the research and planning phase of our very first marine tank and because we really enjoy the DIY side of the project we're going to be building our own nano tank and accessories "from the glass up!" Here come the questions...
For arguments sake we're looking at 3 to 4 fish, some snails, some of them long legged spidery looking critters and some softies in a tank with a 20 to 30 gallon capacity...
1. Which is better - long and shallow or narrow and tall? Which would the critters prefer?
2. Substrate - Is it safe/morally acceptable to ask a relative on the south coast to bring me a couple of buckets of beach sand? I've seen mention of playpen sand and I have a couple of bags left over that I bought at builders warehouse. I wanted to use this in my brackish tanks but it started turning black in places and was a pain in the ... to clean!
3. Skimmers - Found some great DIY plans but having never seen 1 working...
- What happens to the dirty water collected in the cup at the top?
- How much water usually collects in that cup and how often would I need to drain it?
- I've also read that it's better to pump the water slowly through the skimmer to give it more time to work - any thoughts on this?
4. Water - What sort of price can I expect to pay the LFS per liter for pre mixed?
5. Filtration - sponge + bio balls + activated carbon + live rock - anything else needed or recommended?
6. Live Rock - I've seen it mentioned that LR should take up around 20% of your tanks capacity - How would you calculate how much LR is needed? Does 1Kg of LR displace 1Kg of water etc?
Thats it for now - I'm sure there will be a lot more questions as I progress!
I'll work on some CAD drawings of the tank this weekend and post the results when done! I'm very much eager and excited!
