Ro/di

[cuttingras]

I have a new RO/DI that I'm hooking up. When I do top offs should I add calcium or ph? What do I need to add? If anything?

Your RO/DI water will have a pH of 7.0 which is obviously lower than you would normally want. However, unless you're adding a ton of it at once, I would worry about it.

+1 for what curt said

into my 55gal tank, I usually fill it up about 1 inch a week. Is this normal, seems like a lot me? I was using the tap water and putting ph & calcium into it, checking before and after...of course..

I fill my 29g about an inch every 2 days. My tank lighting is not on a stand causing alot of heat right at the water surface so tons of evap. There are alot of things that can cause water loss but the only one I would be concerned with is puddles on the floor.

[inwall75]

Don't do it once per week anymore. You have RO/DI and you should top off smaller amounts every other day IMO and then you're set.

I usually add about 1 inch in my 29gal which is approx 1 gal every three days

HI,
since I ve added a sump to my system my tank levels are constant, I have marked the sump at a point when all the water has returned after powering down this becomes the max fill power off.
This prevents floods, I usally power down filter when feeding to prevent food being trapped in my canister filters.
I find that can add alot of waste to the water that isn't even being utilized as food.
If you loose power it will not flood the floor either.
I have seen one memeber use a large rubber maid as a resivor and a simple float powered pump to top of the sump as needed , neat idea and can be built fairly easy, my tanks use a lot of water cause i have them open no covers i also have 2 over flows and two skimmer they inject moisture into the air by generating all those bubbles, I currently loose around 1/2 gallon of water a day to evap.

Might you have some directions for setting this up? 1/2 gallon a day...wow I thought I lost a lot I just put the clear glass with extension covers on mine, seems to have slowed down the evap.
