Strictly speaking, the brown stuff on your rocks and sand is almost certainly not algae but cyanobacterias, in which case they will forever be in your tank. However, with reduced nitrates, phosphates and good water flow they can be controlled and put in check. It would be best if you can remove...

As Carlo has pointed out, wavemakers and top-offs can be as bad as the lighting blips. They ARE strikes of lightning every time when they open and close the circuit :)

:) I am usually for the analythical quantitative aproach, but in this case I will stay with the empirical aproach: almost a year after I changed my RO (only 3 stages) filters and membrane, all my corals, fish and rest of micro and macro life in the tank is thriving and growing :)

That is in no way detailed , just an overview. For the real details, you have to start researching further, to figure what is best for you ;D

:) no offence taken, whatsoever. It is true that in summer, my heaters are not on, most of the time, but they do turn on and off at some times, and they will drain the battery fast. Remember, this particular product has only 50Wh in it (will drain in 3.7 min at 800W). And even if we forget the...

While normal source of Ca in aquariums are from - salt mixes through water changes, and - dissolving of sand and rocks this is not sufficient for corals that are building coral skeletons, in which case Ca is usually added to the tanks in the following ways: liquid Ca supplements Dissolved...

Heaters on any system 50 gal and up (lets say 100W heaters) will drain it in 25 min or less.

Valonia (most probably in your case though it could also be Ventricaria) bubble algae are very hardy and you won't be able to starve them with chaeto algae. Of course, you are more then welcome to some of mine (chaeto) if you wish to come to Plainsboro (08536). You can easily remove your bubble...

There is no general consensus about almost anything in this hobby ;) It is up to you, if they are aesthetically pleasing, as long as they don't start choking and overgrowing other stuff.

Jorge, I think that a lot of people here would like to know your secret for such good pics ;D and would appreciate a lot if you tell us what equipment you are using and at what settings. I have definitively found your tip yesterday, for focal length extender, extremely helpful.

I also use one (2 years old) and it is fine on my 75gal. Definitively use Maxijet pump (so many bad reviews about Rio pumps), or even something stronger. The only important thing you have to remember with this skimmer is that you have to keep the neck of the collection cup as clean as possible.

;D not all of them - some of them are really ugly ;)

You will definitively have to regularily feed that fish. I seriously doubt that the amount of sandbad you have will be able to sustain that on its own. It will clean it in a week or two.

Very nice fish. I am concerned, though if you would be able to keep it in such small tank. A month ago, I got a similar species of goby - Rainford's goby, that feeds in the similar way (sand sifting), and mine still won't touch prepared foods. I guess I have a plenty of crap in my sand for it to...

If you are refering to the whitish stuffin the middle of the pic, I would guess they look like mini featherdusters - or some similar type of hydroids. Hard to tell from that pic.
