evaporation

  1. General Reef Discussion
    Hey Y'all! So I finished my DIY ATO system before the weekend, took some tweaking to get it setup, but I got it working great. It cycles on and off fairly often (I only used one float switch), so I will eventually move the return for the ATO to my overflow box, so that it won't cycle as much...

    I'm wondering if anyone has had a problem with mold and fish tanks. I recently (Sept 4th) moved into a new home I am renting. I am having to scrub mold off the walls in certain places with bleach that keeps reappearing. I am pretty certain it is not my 40 breeder tank as I only replace about 3/4...

    I am on day two of a 10 gallon nano reef cycle. I am expecting about a month for cycle to complete as this has been the norm for all my tanks in my house over the years. My question is what do I do about water evaporation? Do I replace the evaporated water while it's cycling? Any advice or...

    I have been doing some research on this subject and I have found many different opinions on this matter. The matter at hand is this...no more water changes OR not as frequent of water changes anymore...this is due to the amount of water you lose to evaporation. Right now I currently have a...

    I have a silly thought of using AquaClear 50 for my 5g tank as both Filtration unit & ATO unit. One of the main reason is because I wanted to add more filtration, even though the tank itself already has 1 level of bio wheels and 3 levels of ceramic rings. I don't think there is any harm in over...

    Guys, Another stupid question ... but am keen to find out what the answer is. When I top up with RODI water, I can see there is some sort of separation effect between the tank water and RODI water and after few quick seconds, they all become saturated. What is this? are they normal? Does it...

    Hey yall, So I'm about 3 weeks into my nitrogen cycle, and am already seeing orangle/brown algae on both my live and dry rocks. There is also one anemone growing on the live rock and green grass looking stuff growing on the live rock. Hopefully those are good signs? lol So my question is...

    So after I got rid of my canopy and went with t5's I've noticed that I'm losing a lot of water due to evaporation. Like a gallon every 3 days. My question is... if I'm putting in at least 2 gallons a week of fresh water is there really a reason to due weekly water changes? 2 gallons a week...

    Ok guys got a question for all you. The higher the water level is in your display tank the higher the water level in your sump should be....right? At least that's what id have to assume because of gravity. So my display level and sump level will be exactly where I want it to be. Then my display...

    55 gallon tank with glass lids doesn't evaporate water. I know it is but just at a very slow rate. I did a water change two weeks ago and have yet to add any water. I was very careful how I cut my plastic around my tubes and wires. so that there may be a total of 2square inches total of lid...

    So coming from an open top setup with sump and constant water surface agitation I was expecting to be needing to keep right on top of the water evaporation due to it being a nano setup and sg swings are huge. But 4 days in and I have noticed a minimal if not no change in water levels. What is...

    How often do you guys replace your refractometer calibration solution? Im guessing that there will be a bit of evaporation in the bottle, throwing off your calibration. How often before this happens on average?

    So I've got the tank and sump up and working, flow is good, but....... There is a lot of moisture in the air now and I'm worried about mold. Is this a concern I should have, should I get a dehumidifier? I have the glass top on the tank and it's crowded with droplets of water from the...

    Does any one know where I can pick up a decent RO/DI unit for my system? Currently my average evaporation rate is between 5-10 gallons per week so I do not need anything huge. I do not really want to deal with hooking up an auto top off function. I currently live in a rental house so I don't...

    Well after much of my own research online:read: but not much personal experience, I decided to come to you guys for the answers. Which do you use? A Hydrometer or Refractometer I know refractometers are generally viewed as more accurate. I would like to hear from people using both who are...

    Hey Guys! Its been awhile since i've been on so I made a new account. I finally set up my 72 in wall bowfront tank! I had to move over the inhabitants of my 8 gallon right after set up though cause it was right on the verge of a terrible crash (started the tank off on the wrong foot a few...

    So i'm trying to maintain my Salinity Levels and i noticed when i test the tank at different depths of the tank i get different readings. at the top of the tank its off the charts. Middle of the tank is at 1.024 and at the bottom its 1.020. i took these readings a day after adding fresh water...

    I have recently ordered some leds and am really wondering the pros and cons of taking the glass tops off my tank. If I do what should I put on top to deter escapees? I have a canopy but its open on the top to let heat out. I have a 175 gallon bowfront with dual corner overflow. Which brings...

    Hello! I'm not sure if this is a stupid question or not; it is merely an idea. For topping off evaporated water, would it be possible to use a drinking water filter? Like a Brita water pitcher or dispenser, that makes purified drinking water from tap water? Let me know your thoughts! Thanks!

    I have an open hood biocube 29 (because of heat problems) with a mh light. each other i have to top it off with about 1/3 gallons of water. i know thats not much, but its still cold in seattle and summer is coming soon. is there any way to keep the evaporation to a minimum?
