new ro/di-how big of water change

[tallyho]

Just got a ro/di this week< I have 150 gal fowlr, contigent upon
matching Ph,salinity,temp...how big a water change would you
risk?

 

[beaslbob]

0%. But that is just me. Why are you changing water?

 

[tallyho]

I have been using tap water for 2 years...too much brown algae
I definitely agree with consensus that partial water changes are good

I would do like 10% a week until everything levels off. No more than 20% IMO.

Beaslbob, you just dont get it. Stop being a little whiny protestor against RO/DI and sticking your nose in every freakin conversation about it adding your worthless two cents.
I agree people have varying degree's of tap water(some better than others) but if humans can drink it, it simply doesnt mean fish can. THEY BREATHE IT. If humans were exposed to high toxins in the air and the comparison was one to one, we would be miserable (and short lived) as well. Its just not a big investment and you gain a lot in the longterm by keeping the water pure and the algae down.
