Re-Fresh revitalizes old, green/brown aquarium water. Re-Fresh is a potent combination of beneficial bacteria that work together to maintain clear water, clean aquarium surfaces and eliminate unpleasant odors.

Because the condition of every aquarium varies, it may be necessary to add Re-Fresh more frequently to achieve desired results.

No one wants an aquarium covered in green or brown grunge that smells. But many people do not want to add toxic chemicals to their aquarium either. The answer is DrTim’s Aquatics Re-Fresh. This 100% natural product is a potent mixture of beneficial bacteria that work to eliminate green and brown grunge in your water and on surfaces in the aquarium.


Shake well before using, and add 5mL per 10 gallons of aquarium water once per week. Since every reef tank is different it may be necessary to add Re-Fresh more often to achieve desired results.

For the best results use with Dr.Tim’s Waste-Away.

Caution:  Re-Fresh may be harmful to snails and shrimp.  Do not overdose on tanks containing these organisms.  Wait 5 to 7 days after final dosing to add these organisms.

How to Get Rid of Algae and Cyanobacteria

The traditional methods of using antibiotics and algaecides have one “benefit” – they work fast. You can usually see results in a day. But this “victory” is short lived and the cyanobacteria or algae come back even stronger than before because, as mentioned earlier, the decaying dead cells become food that spurs the re-growth of the algae and cyanobacteria. The 100% natural alternative method presented here takes a little longer but does not involve any harmful chemicals or antibiotics, just beneficial bacteria that GET TO THE SOURCE of the problem.

Here’s how to proceed:

1) Manually remove as much of the algae/cyano as possible by siphoning, netting and micro filtration.

2) Use DrTim’s Re-Fresh for a total of 10 to 14 days, adding Re-Fresh every 3 to 4 days (dosage is 5 ml per 10 gallons aquarium water). Reef tank owners – beware that high doses of Re-Fresh may harm snails and shrimp so these organisms should be removed from the aquarium.

3) After the Re-Fresh regime, dose the aquarium with Waste-Away. Start with a half-dose (5ml per 10 gallons). Add another half dose 2 days later. If there are a lot of organics in the system you may experience cloudy water. This is a sign that the beneficial bacteria are working but also a sign to proceed cautiously because too much of a bacterial bloom can lower the oxygen to dangerous levels. If there is no cloudiness, add a full dose on day 4. Continue to add Waste-Away every 2 to 3 days (watching for any cloudiness) for 2 weeks. Generally at the end of this 4 week period of adding Re-Fresh and Waste-Away, the tank will be clean and there will be a noticeable improvement in water clarity and cleanliness of the substrate.

4) Once the aquarium is looking better, Waste-Away should be added on a routine basis – at least every month. However, it is important for you to evaluate the reasons for the organic build-up in the aquarium in the first place. Is it the result of overfeeding, overpopulation, lack of routine cleaning? To save yourself continued headaches, a critical self-evaluation of the causes is warranted and action needed.

Discussion and Directions
Dinoflagellates are a diverse group of single-celled eukaryotic organisms that can quickly take over a marine
aquarium. Technically, they are not an algae or an invertebrates but protists. Protists are a catch-all group of
organisms that don’t fit into the normal groups of animal, bacteria, plant or fungus. The most important thing to
know about dinoflagellates, when trying to eradicate them, is that most are photosynthetic.
The process, in a nutshell, involves covering the entire tank with black plastic and turning off all the lights (what
is called a dark phase) for 3 days while dosing Re-Fresh each day. The lack of light and Re-Fresh will stress/kill the
dinoflagellates. Then you start adding Waste-Away to breakdown the organic matter from the dead dinoflagellates
turning it into more bacteria which are removed by your protein skimmer.
Some general questions are: Will the dark phase kill my corals? In 99% of the cases, no. If you are worried about
a specific coral you should remove that particular coral to another tank. Will the dosing of Re-Fresh kill my shrimp
and snails? This is a slight possibility, if concerned, best to remove those animals to another tank.
CAUTION: for best results you need a skimmer to remove the bacteria that will be produced and to help prevent
bacterial blooms that may result in loss of livestock. A filter sock can help but will need to be cleaned daily

So let’s start – Wrap your tank with the plastic black. The goal is to prevent ANY lights from getting into the
tank. Also disable the lights so they are off during the entire 3 days. Add Re-Fresh to your tank at a rate of 5 ml
per 10 gallons (see back of bottle). Turn off your UV and skimmer (plus ozone if you have it) for a few hours BUT
observe your tank with a flashlight. NOTE – if the water starts to turn cloudy turn these back on ASAP*.
Day 2 and 3 : Treat with a full dose of Re-Fresh leaving the skimmer, UV off for a few hours each time.
Day 4: Unwrap the tank, start a normal light cycle. You may not see much of the dinoflagellates but still start
dosing with Waste-Away*. Start with a small dose. The bacteria will break down the dead organic matter producing
more bacteria and if you add too much bacteria they can reproduce out of control (called a bacterial bloom) which can
remove all the oxygen from the water harming your fish and corals.
We STRONGLY suggest you start with 1/4 of the normal dose (or less). Read the back label of your bottle for
dosing directions. Turn the skimmer, UV and ozone off for 2-4 hours. But if the water starts to turn cloudy turn these back
on ASAP. Do not dose and leave the tank unobserved at first! Every tank reacts differently – watch your’s closely.
Days 5 – 8: Continue adding Waste-Away slowly increasing the dosage amount. You can even consider adding
a few small daily doses leaving the skimmer off for a little while allowing the bacteria to consume the organic
matter then turning the skimmer on the remove the bacteria. You continually alternate between adding bacteria and
removing the bacteria with the skimmer instead of one larger dose a day.
Day 9: Do a partial water change. Your tank should be looking better but in hard cases you may have to repeat
the process. To maintain a clean tank we suggest you start using our Waste-Away Time Release Gels.
*Precautions – If at anytime the water turns cloudy TURN ON YOUR SKIMMERDO NOT add more Re-Fresh or Waste-Away until the water
clears. Do not dose both on the same day. Proceed slowly with dosing Waste-Away if the tank becomes cloudy do not increase the amount of
Waste-Away. A little bit each day or twice day is better than a big dose at one time.
