For some reason I was thinking your gravel was too big rather than it being blue..

Actually in response to sincrisis, if you water is high-ph and hard, the ph probably won't change at all... Soft water would me bore likely to have a large ph spike...

I've read Eco-complete will raise pH marginally at the beginning, but I've not personally used it. I doubt it would be a significant change. When I set up new tanks or re-set existing tanks the pH is initially higher than the existing tank but that has never casused a problem. When I transfer the fish I use a 2g bucket half filled with water from the existing tank, the fish are netted into the bucket (several at a time), the bucket is then filled up with water from the new tank, and after maybe 5 minutes the fish are netted in to the new tank. Some believe this fussing is unnecessary. Many authorities suggest that fish can manage a pH change of up to 1 degree, that is as an example from 6.0 to 7.0, though in my case the change is less, maybe .6 or so. A one-time change is not the same as fluctuating.

Water conditioners work immediately. As long as there are lots of plants, there should be no problems.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

my water is super soft due to a softener system, my ph, is 7.6 out of the tap and was 7.8 when i first had eco-complete for about a month with steady 15% water changed each week. Then it settled down and I added driftwood so now my tanks at around 7.3-7.4.
