A question about prime....( John or Neo )

[Boydo]

For the 550 gal I use a RO/DI unit that is changing 100 gallons a day...I have chloramine here so I dose the tank with 20 mls( enough for 200 gallons) of prime daily. So is this too much prime?...are there any known down falls of using prime like this. Would it be best to only add enough for the water being changed.

Thanks in advance....

i have used prime with "OD" with no side affects but not 100% w8 for other ppl

You could easily cut back down to 13-16 mL usage a day. You a theorecticly doing a 200% overdose.

so the water is from RO? then you dont need to add prime... you need to add RO-right..

as for dosing .. you can safely dosing up to 5x the recommand dose


here is from seachem.com

DIRECTIONS: Use 1 capful (5 mL) for each 200 L (50 gallons*) of new water. For smaller doses, please note each cap thread is approx. 1 mL). This removes approximately 0.8 mg/L ammonia, 1.2 mg/L chloramine, or 3.3 mg/L chlorine. May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. Sulfur odor is normal. For exceptionally high chloramine concentrations, a double dose may be used safely. To detoxify nitrite in an emergency, up to 5 times normal dose may be used. If temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose.

does the chloramine show up in your tank or just out of the tap?

That's not too much, but you're probably wasting it.

You don't need prime at all with RO/DI water. You need a buffering agent as neo recomended. I run 12 tanks on RO/DI water and we use crushed coral along with a small amount of salt to buffer the water to a stable 7.6 PH but RO right works great.

Reverse osmosis removes the chlorine and just about everything else on it's own.

Thanks for the replies, I should have mentioned of the 100 gallon change out only 60 % goes through the membrane the other 40 % gets pre filter - carbon block - active carbon. The chlorine is removed but not all the chloramine that why I use the prime dosing, I just wasn't sure if the amount I was using was maybe too much.
