When I was buying my float switches, manufacturer himself was warning about possible freeze of switch in closed state (permanent magnetization of contact strips), so I have bought 2 of them and connected them serial (logical AND ;D) so now I have greater reliability. Just for fun, I have also...

Since they tend not to swim in free water column, but to stick to surfaces (substrate, glass, rocks, corals plants) and they shy from vigour water movements (fuge overflow return flow), it could happen.

post your pic here as well.

Well, it doesn't "feed" (not in the amounts that you would normally consider as feeding) but it still might be calcareous which means that uses Ca for enhancing the outer layers. Now, most fish will prefer to eat non-calcareous algae so that would be a problem. Fortunately, calcareous algae tend...

If cyanos would encroach on a corals in a well established and mature tank, then you might try to use something drastic like that. However, since his tank is only 2 month old and is nowhere near being in balance, then this treatment, IMHO, will do him more harm then good - in the long run. Since...

You use RO/DI and still get any phosphates? Maybe you need to change the filters. Or test kit. Just a couple of notes about the Naso so you know exctly what you might get with this excedingly beutiful fish: - It can be pickey eater. Mine was eating ONLY macroalgae, preferably fresh and I had a...

Interestingly, that seems to be quite uncharacteristic picture of Majanos. In no other picture I have seen on the web, nor the one specimen I had in my previous tank, did the Majano had so extended body. Since the whole anemone is very small, the body is usually wedged in some small hole in the...

Or he could just wait a bit more for a tank to mature and at the same time do more aggressive skimming and nutrients control, reduce feeding, collect the biomass accumulated in the bacteria mats, modify the water flow and let his cleaning crew mess with the rest (my buble-tip brittle star likes...

How big is the tank? I had a Naso tang (Naso lituratus) that was exceptionally good in devouring any kind of macroalgae. However they need a bit larger tanks. Yellow tangs are also good algae eaters, but more for a filamentous algae. This one is not that, but you might try your luck with yellow...

Actually IT IS ALIVE !!! :) You already have gazillions of live organisms in it. Spores of bacterias and other organisms that were in the air, on your hands, in the old tank, sand, rock, sump that old pump etc have already "hatched" and are "catching rays" from your lights and happily munching...

He is right, specially if the rock is not fully cured and/or has a lot of organic materail from the past. And then, skimmers also skim inorganics too. All of the dust and some of the disolved minerals from the rock and salt will be picked too. And since you have created your own rockwork (if I...

Majano anemones? Just google them and you will find thousands of different pics, which will be helpful in distinguishing them from aptasias and button polyps.

The same company (EcoTech) that makes vortech pumps also sells kalk reactors for 350$ which utilize the stirrer (http://www.ecotechmarine.com/products/REACTOR.HTM). However, you can find used lab stirrer from e-bay for less then 20$ and a new one for 100$ (cheap ones), and will work fine with...

Interestingly enough, I had some hydroids on a small rock which has several ricrodea mushrooms on it. 6 motnths ago, mushrooms were 1/2" to 1" in dia. and hydroids started overgorwing the rock. Then couple of months ago, ricordeas started growing like crazy (I tried to remember if it is just...

I have quite a number of small Kenya trees frags that I want to get rid of if anyone wants them.

Carlo, I believe that I have seen CORDLESS powerhed in Merv's tank (6 moths or so ago). The coolest thing I have seen in a long time. And it looked powerfull enough. AND you don't need any suction cups and mounts or anything to make it very firmly stay in place. Check with him about it.

He was also asking about sand and rock. I don't know about the rock, but I am pretty much sure that I have seen somewhere the discussion about sand and how it is ilegal to take sand from beaches. Also, you should consider all the polutants you might get if you collect rocks and sand here. From...

This article talks about limpets, kehole limpets, coraline algae and hydroids: http://www.reefkeeping.com/issues/2004-06/rs/index.php

If in doubt leave it out. Superglue is not so effective for softies, they shed mucus and slime when stressed. What is often recommended for marshrooms is to temporary cover/fix them with the light veil mesh. You can also try to crush the rock. If you have sharp and precise bone cutters (pliers)...

I use the plastic mesh used for basis of cross-stitching that have I bought in Walmart for ~50c It is 12x12" and the mesh openings are 1/8" . You can use a small piece for pipe reutns and pump intakes by simply folding it and sticking it into the openings. For owerflow, you can cut it an and...
