    I am setting up a 10 gal nano with only biological filtration, bare bottom, lots of live rock, corals and one fish and some cleaners. Do I need an airstone or not? Thanks

    Question- I have a blue moonlight that stays on in my tank at night. The fish seem to gravitate towards it, going to the top center of the tank, under the light. Is this just some natural instinct or is there an oxygen issue? Thanks!

    What is the best way to increase oxygen levels in my saltwater tank? I do not want a bubbler because of salt creep so what is an alternative way? Thanks!

    Finally got myself a 40 some pound batch of soda lime. Hooked up to two canisters splitting the air input from my skimmer, 960 lph of air total through it. My first thought is 'oh no!', but then I look at the specimens I have in the tank. All fish are acting normal, eating normal, quite active...

    So i have a 60l Dennerle Cube and it has a lid that covers everything, except two corners and 1cm on the sides. I lost two fishes already because of jumping out. If i close the corners and sides somehow (how?), what happens with oxygen levels inside? Everything ok or i should leave something open?

    Hey yall, quick question. Right now I have my powerhead positioned near the top of the tank pointed downward facing the glass in the middle of the tank. Every minute or so a tornado of air spirals into the powerhead, blowing bubbles that cycle throughout my tank and loop back around. My tank is...

    Hello, i was thinking that algea absorbs oxygen from the water, is this the case? Im having problems with green fuzz all over my back glass and power heads. Not sure if Growth will increase if i clean it off- at a crossroads: (

    I have a 46 gallon bowfront FOWLR tank (currently just crabs, snails, and a pincushion urchin). Setup includes a Reef Octopus HOB protein skimmer, live rock, a Fluval 304 canister filter for flow (no media, just carbon & live rock rubble), and a Koralia 750 gph. No matter which way I aim the...
  9. Skimmers & other filtration
    hi, im using an aqua one g220. I keep my tank almost entirely covered so i get little to no evaporation(heaps of water collects on the glass). So im wondering if having the skimmer on at night will be sufficient to keep the oxygen level in the tank at a suitable level or will an air pump be...

    http://www.sciencenews.org/view/generic/id/349906/description/Why_corals_do_calisthenics Seems that the level of oxygen in the water affects how strongly these corals "pump." Could be good, cheap indicators of O2 levels? On the other hand, our strongly oxygenated tanks appear to have some...

    Situation - I work away from home for periods of up to 3 weeks. Fish are fed daily so please dont think I am neglecting them. Due to space limitations I have had to construct a DIY sump which includes and V2 400 skimmer and a small 9 watt UV sterilizer. That compartment then trickles through to...

    Hey guys. I've been reading up a lot lately on micro bubbles. Specifically the pros and cons of them. I am curious because in my 150gal reef tank I am currently using two power heads for flow that have built in venturis that add bubbles to the water (similar to an air stone). I leave them...

    Just a little background first. I have a 29g bio cube and has been up an running for about 2 months now. The past 2 weeks I have seen the diatom bloom and recently it seems to be subsiding. I am wondering if during this period that the diatoms will reduce the oxygen levels in the tank? I lost...

    Hello, i just got back into reef tanks and have just started a 55G Its been up for about a month and a half now and i have cycled through. There is about 20lbs of live Fiji and 20lbs of dead coral(soon to be replaced by another 50lbs of live fiji). I purchased on craiglist and complety bleached...

    I just picked up a JBJ Nano cube 12g for $50 (good deal I thought). I'm not sure what I want to keep in this tank but probably SPS, zoas and a clam. About 10-15lbs of LR raised slightly off the bottom. BB of course. Maybe 1 small fish. I'll do a 30% WC once a week. I'm making the following...

    I know, I know, tons of algae ....I have been manually taking it out every other day and doing my weekley 15 % WC , the tank is 3 mo. old and I think its still at the end of cycle! Nitrates are 20ppm. They were 0 for the first 2 mo. ...Any way I was wondering if these are oxygen bubbles and not...

    Hey everyone, I have a serious PH problem due to my apt being wound up very tight. Rather than go the auto top off or drip method I have though about: Using a 250gph powerhead with a airline input on it ran from 12am-8am on a timer with the airline hose fed from outside for fresh oxygen. The...

    I was listening to Eric Borneman's seminar on oxygen the other day, and it was interesting. It challanged a few things that were thought to be well understood. Like the fact that a skimmer helps produce 02 in a tank. But according to his findings it really didn't do that much. It seems the main...
