Buying a tank

Posted 09/15/2014 at 08:44 AM by Sk8r

Buying a marine aquarium
...most fish stores cannot stock the size of tank appropriate for most of the fish they sell. Tanks of 30 gallons or under are appropriate for a clown pair, a few gobies or blennies, a royal gramma or dartfish, and some inverts. And with good lighting---corals.

If you want larger fish, you have several size jumps. A 50 will let you have a dwarf angel or similar, anything a 30 can handle, maybe a single chromis (a damsel, like a clown, mildmannered,...

DO I need a...[skimmer, filter, ro/di, reactor, ATO, etc.]

Posted 09/12/2014 at 12:05 PM by Sk8r

Understand, you can run a very simple kind of 30 gal tank with nothing but a pump, a heater, live rock, regular tank light, and a Penguin filter, with a 'fill line' drawn on the glass to help you top off accurately with ro water from the supermarket. This is the ancient method. It will support a few crustaceans and snails and a couple of very small gobies or blennies or dartfish.

If you want more than that, your problem becomes too much nutrient in the system, not enough waste removal,...

Cycling does not mean turning your tank into a toxic zone...

Posted 09/12/2014 at 11:22 AM by Sk8r

I've read an increasing fervor for dumping various things into a new tank to cycle it, many with the implication it does it faster---and some involving a lot of extra expense.

Cycling is a simple natural process of letting bacteria multiply and penetrate more than just the outer skin of your rock and sand. And bacteria multiply quite nicely without your doing more than setting up with one live rock amid conditioned (saltwater soaked) plain rock. I've even done it with no more than...

Choosing and maintaining sand

Posted 05/20/2014 at 09:50 PM by Sk8r

Sand: buying it, keeping it.
Avoid silicate sand. Go for aragonite, which is basically calcium carbonate and safe.
Fine or medium? I can only tell you personally, with an sps reef, in a re-set-up, I tried fine, and spent the next 2 years removing it, after it killed corals. I'm definitely on the medium side. The fine sand, though amply bacteria'ed, would not settle, blew like mad, irritated corals, and was a mess. The medium sand has enough 'shape' to it to enable jawfish to build...

Do I need a filter...FYI.

Posted 05/14/2014 at 11:52 PM by Sk8r

Yes and no. Depends.
A fish-only may benefit from a filter in the system, but!
Here's a list of useful facts to consider.
1. ONLY live rock and sand can break somewhat-harmful nitrate all the way down to harmless nitrogen gas. Bioballs can't and a filter can't. They take waste down as far as nitrate and stall there. Nitrate builds up and up until there's a cleaning-out of same.
2. Fish can tolerate higher nitrate than corals can. They'd probably rather not tolerate it,...
