Way to slow down evaporation

[nycdominicanreef]

So here's the situation. I have a 75g, with a 3chamber sump. chamber1 has my 2 heaters, chamber2 has my skimmmer with 2pumps( 1for recirc(rio-3500,1 to feed(mag5) water to the skimmer), Chamber3 has 1 pump (mag9) for the return. I feel like these pumps evaporate alot of water. Any suggestions?

All pumps give off heat.Evaporation is one way to it deals with it which is natural.You can use external pumps.

Using an external pump doesn't eliminate evaporation completely but it does help quite a bit so i've noticed

If you can find a way to cover your sump it'll help!

 

[kalapnath]

I don't know if covering your sump in 80 to 90 deg weather cond will help you with evaporation

Bye the way how much evaporation do you get..............

bout a gallon, and this is with my lights off. I havent put any corals in yet

 

[kalapnath]

A gallon a week is not that bad i do 5 gallons a week

 

[nycdominicanreef]

gallon a day

So you have to turn on your RODI for 20 minutes a day. boohoo.

Or just get a bucket of RODI water and then flick a pump on, thats about 10 seconds a day.

Or get an ATO for 0 seconds a day.

Are you an Investment Banker who is working 24/7?

I'm not an investment banker, just a personal banker and work 8/5. And i wasnt complaining, was just asking for a suggestion so if u cant address my question dont add your 2cents

From what I have read, covering the sump would help. So would slowing the flow of the water through your sump.

IIRC fast flow through the sump = faster evap.

 

[masterswimmer]

Less evaporation = higher heat (more than likely).
Cover your tank = higher heat
Cover your sump = higher heat

Most people prefer to use evaporation for cooling their tank, you're looking to do the opposite. Makes you wonder if everyone else is wrong :scratchch

My 75g evaporates 1-1.5g every day (the variation is due to seasonal changes). Your evap is normal......and healthy for your tank.

but as stated before it will create alot more heat in the sump.

Thanks Masterswimmer, You hit the nail on the head

Just wanted to add, there is no real correlation between external pump and lower evaporation. I'm not sure where people got that from, but you'll evaporate more if there's more surface agitation (water pump), more air flowing on that surface agitation (fan), and if that air is less humid (depends on the weatherman). So the opposite will hold true if you want less evaporation.
