Aquarium Fish Tank 50

However, if you dont have a choice, and need to bring your fish inside for the winter, be sure to have an aquarium air pump or small fountain to provide oxygenation. The fish should be fed infrequently, if at all, depending on the water temperature. pH, ammonia and nitrite, which should be monitored weekly and especially if the fish are fed.
Small water changes (20%) each month will keep the water in good shape until spring. Koi are "jumpers"-so be sure to cover the pool with bird netting!

Overflow Boxes vs. Drilled Fittings:

I tend to be more charitable re these devices than several of my cohorts. Overflow boxes are for folks who have not or dont want to have their tanks drilled, but instead come to rely on hang-on arrangements that in turn are subject to tragic failure... counting on sufficient water level/s, a lack of blockage by livestock... IF you want to use overflow boxes instead of drilling your tank/s, DO use at least two (yes, I know theyre expensive... so is your gear, livestock, flooding, divorce) on ANY size sy

You might ask (at least I do), "Why dont you see all this filter gear on the reefs in the wild?" Well, you kind of do. Next time youre underwater, take a look around. There really is a lot of water per unit of livestock, and lots of circulation and aeration. Notice the predominant forms of life around you; corals, sponges, bivalves... What mode of food gathering do they employ? Theyre mainly filter feeders, sieving out plankton, gametes, wastes, suspended inorganic material... thats why the waters so clear. Stuck in and amongst (and inside other life) are algae, some big, others micro

Whats the best means of securing the threaded nut to your through put fittings? With a smear of 100% Silicone Sealant... allowing a bit of shaking, tank movement (they do at times) w/o breaking... and even the possibility of easier removal should you want to... Did a gasket (maybe two) come with each through-put fitting? Smear a little Silicone on either side of it and the flat of the fitting and place it... on the inside of the tank side... if/shou

Ahhh.

Lets journey together through these various components:

Tanks:

There are two general varieties, plastic (acrylic) and glass (with silicon rubber seams. Some important considerations: They are heavy when set-up and filled; about ten pounds per gallon! Therefore it is important that aquariums be placed on something substantially strong. Another factor is that this "stand" be flat and planar. For these reasons Aquarium manufacturers will generally warrant their products only if they are placed on certified Aquariu

Question about rock
I am not sure if this is the place for this, but I had to start somewhere. I am going to be doing a 90gal. soon and wanted to know if I can use limestone as a base for my reef? I want to fill the tank with the limestone and then seed it in areas with high quality live rock. If I cannot use....

SE vs DE
I did a search but my searching skills suck I guess. I'm trying to figure out if DE is worth the cost over SE for a dual setup over a 75 or a 90 gallon tank, haven't decided yet, but I obviously want the most light for the least money :) DE bulbs are more expensive (seems to be), and the pendants are definitly more costly than a simple reflector and I already have a socket a.
