Ghosty problems in your tank? Consider your nitrate level.

Posted 07/24/2015 at 03:20 PM by Sk8r

Recommended or a reef---level of 2 or less.
For a FOWLR tank or fish-only: less than 30.
For many inverts, the survival limit: under 40.
Fish survival limit---maybe 100, but it's not going to be happy.

Some things actually use up nitrate: clams, for instance, reduce nitrate, but have many other high-end life requirements, so don't dump some poor clam into a fish-only.
Some corals like elegance also appear to require a little, so zero is not good for them....

A corals-first marine tank

Posted 07/11/2015 at 02:22 PM by Sk8r

A corals-first marine tank...
I've discussed this a couple of places, and some people are doing it, but let me put forward the advantages and the problems---if you have done or are contemplating doing it, chime in. It's at least worth a consideration, counting how prevalent parasites seem to have gotten in the hobby...

Pros
You can start setting up right after cycle.
You put your cuc in, dip, (do a short observation after dip for zoas, particularly) put a number...

How secure do you WANT your rockwork?

Posted 07/04/2015 at 01:52 PM by Sk8r

How secure do you WANT your rockwork?
My answer is 'not secure'. I balance, prop, lay it a bit like decorative brickwork, but what the ancients called 'drystane' or dry-stone, despite it being underwater. This means I rely on natural balance, I make my arches out of post-and-lintel and rely on gravity, and I do everything I can that way.

Why? Why not make it one rigid form that nothing can ever shake?

Because I have had to go in and do a fish-extraction that...

Do you need fish at all?

Do you need fish at all?
Short answer, no, not really.
Many people assume corals are the hard stuff. Some are. Many are so easy you have to be careful or they'll be like crabgrass.

One of the problems people have as NTTH folk (new) is assuming fish are tough. Most marine fish aren't that tough. Not all corals are. But some corals are kill-them-with-flamethrowers tough.

Corals do emit waste, but moderately so. They'll live on light (literally: their colors...

Buying a used tank, or a tank in general: what's good.

Posted 06/25/2015 at 07:51 AM by Sk8r

What's (structurally) a safe tank..buying...and buying 'used'
This comes up now and again---somebody trying to buy a used tank.
Acrylic or glass---both kinds of tanks have their cautions.
Acrylic scratches easily, grain of sand getting stuck under a magnet scraper---glass not so much.
Acrylic unsupported by bracing can, over years, bow outward with the heat and weight of the water and sand. You can deal with this, generally, but do be sure that the acrylic is thick enough...
